Anyone experience any of these?

BMW and dealer service facility state that these conditions are normal:

From a speed of 30 mph (speed offered as example), as the gas pedal is released, to bring the vehicle to a stop or lower speed, when coasting, and/or while braking, as the vehicle begins to slow, the driver experiences a jerk/jolt forward a number times as the vehicle shifts/lurches down from gear to gear (the sensation seems to be caused by an abrupt increase, and then decrease in speed; at least that is what it if feels like, and sometimes it is associated with a clunking sound) as it comes to a final stop. Thus, as the transmission shifts downward from gear to gear so the passenger is correspondingly jerked.

From a complete stop, when placed in reverse, and after releasing the brake pedal, without depressing the gas pedal, the vehicle suddenly moves in a backward motion and reaches a speed in excess of 5 miles per hour.

It sounds like it is getting too much idle throttle opening or something similar. I wouldn't think this is "normal" -- just drove an E60 Step on Friday, and I noticed nothing similar to your description. Go test drive a car on the lot at your dealer to compare.

My 545 (steptronic) is not nearly as smooth (at low speeds) as my 330 was. It seems to lurch in a strange way in parking lots....and I don't think it's caused by my foot twitching. This transmission doesn't seem as user friendly to me.....at least not yet. (2300 miles)
The shifts are very quirky on up or down grades. Hmmm...I need to take more mental notes next time I notice this.

That's not normal. My 545i doesn't do that.

Are you driving on DS mode or the regular D mode? DS is more agressive in down shifting gears. It's also possible that the steptronic program is still trying to adjust to your driving style. Check with your service advisor to see if there are any software updates for the steptronic.

Thanks for your input.

I am driving in regular D mode when this occurs.

The three times vehicle brought to dealer's service
facility the tech, and then shop foreman (who test drove
twice), stated it was "normal," and never wrote it up or took
it in for service.

If this is "normal," then I'm a ballet dancer
with the Russian National Ballet Company. Guess what?

Does it happen all the time, or intermittently?

Do you notice that as you slow down, and vehicle
shifts from - let's say third to second, or second to first -
that the tach increases and you pick up speed for
a bit, before you decelerate further, which might explain
why you feel the lurch?

My 2004 530 has the same behavior. I have taken it in twice but so far the only action by the dealership has been lowering the transmission fluid level. That did help but the shifting is definitely more jerky than my 2002 530.

Early March 2004 build date. By the way...I don't think the jerkiness is related to shifting in the tranny...I think it feels more like short bursts of acceleration at low (parking lot) speeds and only happens in a cold start. The car does 2 or 3 "leaps" when I'm leaving a parking lot at say, 5mph.

Do you think that such "leaps" are normal
when you consider your other car driving experiences?

Why do you think the
"leaps" only happen when the car is cold?

I am having the same problem. My car was part of the 4,000 car recall to replace a bad ECM module. The dealer thought the bad ECM was causing the shifting problem and the new computer would solve the issue. The new ECM didn't do anything and it is shifting really badly.

Two main problems:

COLD STARTS - when I do a cold start, the engine hangs in 1st then jumps into second when it finally shifts. Upshifts are very rough and revs are higher than after car has warmed up. A couple of times I had blue smoke coming out of the tailpipe after starting.

NORMAL DRIVING - car upshifts roughly and at strange intervals. When you hit 40+ MPH and let up on the gas to coast, the car downshifts at 40 causing significant engine drag. If you keep your foot off the gas, the car downshifts again at 30. If you start to brake as you approach a stopsign, the car upshifts as it slows past 20 MPH resulting in a lurch forward that makes you feel like you are going to plow into the car in front of you.

I've taken in the car again today and they are going to check it out again. If they can't do anything about it, I am going to file for Lemon status. I only have 725 miles on it and they've all been really bad. I had a 2001 BMW 530i SP before this, so I do know my BMWs and that this is not right. I was hoping it was just the computer "learning" my driving pattern, but I drove a friend's 545i auto and it was totally different. The shift pattern almost seems backwards.

Anybody have an idea of what this could be?

Link to the Edmunds Article that may mention what you are talking about:

http://www.edmunds.com/new/2004/bmw/5series/100344932/roadtestarticle.html?articleId=102584

My brother is experiencing some jolts in first gear for his 545, so he's checking with this BMW Dealer.

Hope this helps.


Paragraph FROM EDMUNDS:
The driving experience ranged from irritating to exhilarating. Irritation came quickly in low-speed traffic, as the drivetrain responded unpredictably to accelerator pedal input. Too little pressure and the sedan would move out sluggishly. Too much and it would surge forth, leaving the driver to rein it in before it snuggled up to an SUV's rear bumper. The area between these extremes often eluded our editors and made the car a pain to drive at rush hour. In addition, one editor noted that the transmission tended to hang onto first gear too long in these situations — eliciting more thrust than you really want when slogging from stoplight to stoplight. Another observed that when slowing in traffic, the transmission always seemed to be shuffling through the gears, often supplementing the driver's braking efforts with more engine braking than desired.

It's nice to know it's normal, but I think my situation is abnormal in that the effect on my car is significant. It is in the shop right now, so we'll see. It really drives poorly and I don't like it. Anyone else's 545ia shake while in gear and a stop? Please let me know.

Guys, I think we have something here. This doesn't sound like an isolated problem. My 2004 E60 530 is having the same issues. The shifting is jerky, unpredictable, erratic, and downright scary sometimes. I mainly notice it going from first to second but I've had several instances in other gears. At times it seems like it can't decide what gear to be in but other times it seems like the tranny is slipping. I'm going to take it in yet again.

I thought that it was just the "learning" function of the auto tranny, but like others have commented, it's nothing like my old E39's auto. After reading Edmunds and a similar finding in Motor Trend, I'm going to take it in to the dealer to see what they can find. While mine doesn't seem to lurch as much as others are commenting, I definitely have trouble driving smoothly when slowing for stop sign and/or accelerating from 30mph. No problems when reversing, though. Not impressed so far with the new tranny compared to the other 5 auto BMW's that I've owned.

Executive Privilege Road Test: 2004 BMW 545i vs. 2005 Cadillac STS

Variability is no problem, though, when it comes to BMW's 4.4-liter V-8. The Valvetronic engine deals with the airflow restriction of the throttle plate by eliminating it, instead controlling the amount of air ingested by the cylinders by varying valve lift electronically. Stepless variable valve timing for intake and exhaust camshafts and a fully variable intake manifold contribute to a broad, fat torque curve. Output is up, too, 35 horsepower over the previous, non-Valvetronic 4.4-liter engine. This new V-8 feels more powerful than its 325-horse rating might suggest. Part of that credit goes to the 545i's ZF six-speed automatic transmission; first gear is particularly short and gives the engine tremendous torque multiplication for launching off the line at a stoplight. There never seems to be any shortage of gear ratios for the transmission to apply to a given driving situation.

And there in lies another annoyance. One editor noted, "In brisk (but not wide-open throttle) acceleration, the engine seems to lunge from gear to gear, like a chained Rottweiler." Following a line of cars in traffic can prove difficult as well. Under semihard braking, the transmission aggressively forces downshifts, slowing the car unnaturally even after the driver has lifted off the brake pedal as the traffic begins to move again. To reduce the excessive retardation, the driver must step on the accelerator, initiating another forward lunge. Concluded one writer, "BMW needs to work on its throttle tip-in calibration and transmission phasing." Added another, "It's so hard to be smooth, especially at low speeds. Starting and stopping often come off abrupt, no matter how careful you are with the controls."

Heez, thank you for your helpful post.
I took your advice.
I read another car article, see it below.
Think there's an accident that BMW tied with Audi as number 9
per JD Powers initial quality survey:

109 problems for every 100 vehicles in first 90 days!

================

CEO of BMW calls quality a focal point

Panke says No. 9 rank is a concern
September 1, 2004


Clarification: The article in Tuesday's Business section about BMW Chief Executive Officer Helmut Panke's call for improved quality of his company's vehicles had paragraphs out of order. The story appears correctly today.

BY SARAH A. WEBSTER
FREE PRESS BUSINESS WRITER

Due to a production error, one portion of the Tuesday Business section-front article "BMW CEO calls quality a focal point of concern" was in the wrong place.

German automaker BMW AG is expecting record revenues and earnings this year, but CEO Helmut Panke on Monday lamented the namesake brand's ranking in a popular survey of initial vehicle quality, where the label that heralds itself as the "Ultimate driving machine" ranks ninth.

Panke spoke to the Automotive Press Association at the Detroit Athletic Club about the automaker's vision of conquering more of the global market, which includes expanding U.S. business.


Last year, BMW sold 277,047 cars and trucks in the United States, or an increase of 7.9 percent while the overall light-vehicle market was down 1 percent. That was the most vehicles the German automaker has ever sold in the United States, representing one-fourth of its overall sales.


And so far this year, BMW has sold 167,977 vehicles, an increase of 3.5 percent based mainly on the performance of the new BMW SUVs, such as the X3 and X5.


Continuing that upward momentum, Panke said, will require the automaker to remain committed to BMW's brand identity, expand its presence in the booming Chinese market and improve quality.


"We clearly want to be in the top three," Panke said of the quality rankings.


Other luxury makers also have been dissatisfied with their rankings in J.D. Power and Associates' initial quality survey, which ranks customer satisfaction after 90 days of ownership. BMW tied with Audi for ninth place in the latest survey, with 109 problems per 100 vehicles.


While that was ahead of the industry average of 119 problems per 100 vehicles, BMW's German competitor Mercedes-Benz ranked eighth with 106 problems per 100 vehicles.


BMW, which also ranked a lower-than-desired 12th place for long-term durability among consumers, tends to offer more highly technical electronic and software features in its vehicles than other brands. While Panke acknowledged those are added quality risks, he said he could not blame that for the performance.


"There is no excuse," he said. "This is not what our understanding of a premium position is . . . This is one of the focus points for the period ahead of us. We have to improve our quality in order to live up to our premium positioning."


He noted that BMW helped create Autosar, a cooperative organization that works with the European automakers, General Motors Corp., Ford Motor Co. and Toyota Motor Corp. to set technological standards that will help improve quality and costs.


Despite its position in the quality rankings, Panke noted that BMW customers remain loyal.


The J.D. Power survey that ranks customers' delight with the design, content, layout and performance of their vehicles usually has BMW near the top. In the last such survey, BMW ranked second to Porsche and ahead of Asian quality leaders like Toyota, Honda and Hyundai.


Panke said that's because other brands and especially BMW's main competitors, which he views as Mercedes and Lexus, don't offer the excitement and control that BMW does. Sticking to that identity, and having the courage to say no to products that might sell but don't fit the mold, will keep BMW on course, he said.


"We will never build a boring BMW," Panke said.


In a recent report, Merrill Lynch analyst John Casesa said BMW is at the high end of major automakers for spending on capital expenditures and research and development. Casesa said BMW, aided by high margins and its premium revenue position, spends about 15 percent of its revenue on capital expenditures and research and development -- about 6 percent more than the industry average.


"The European (brands) -- BMW, Porsche and Volkswagen -- continue to offer attractive, highly valued and differentiated products for the world's richest auto market," Casesa told the Associated Press. "Each company's tactics vary, but all three are likely to continue to expand U.S. product offerings."


Sometime between 2006 and 2007, Panke said, BMW will introduce a compact 1-series vehicle in the United States, although it will not be the 1-series hatchback sold in Europe. He would not say whether it would be a coupe, sedan or wagon.


A redesign of the popular 3-series is also in the offing, but Panke would not say when a replacement for the 7-year-old product will be revealed. BMW designs, especially of the 7-series, have been controversial, almost avant-garde, and Panke said redesigning a car as important as the 3-series is an "emotional event."


Panke said he was unconcerned that BMW's truck sales -- like those in the general market -- are rising, while car sales are falling. BMW car sales dropped 7.7 percent for the year through July, in spite of popular new models, such as the 5-series and 6-series. Meanwhile, truck sales are up 72 percent during the same period.


He views the trend toward trucks over cars "bottoming out" sometime soon and blurring as crossovers that take the blend the shape and function of cars and trucks become more popular.


Panke was noncommittal about whether BMW's growth in the U.S. market would bring added production capacity to its plant in Spartanburg, S.C., or even a new plant.


Production in Spartanburg has grown from about 50,000 vehicles in 1994 to 160,000 last year. About 100,000 of the X5 SUVs and Z4 roadsters built at the plant, which employs about 4,700 workers, are exported to Europe and Asia, making BMW an export leader in the United States, Panke said.


For now, Panke said BMW is focused on expanding in China, with a new plant. The plant in northeastern Shenyang, built with partner Brilliance China Automotive Holdings Ltd., opened in May and aims to produce 30,000 vehicles a year.

Mein auto:530I

Funny steptronic gear changes ??

--------------------------------------------------------------------------------

I have recently started driving my new 530I and I'm almost always in steptronic mode and enjoying it.

However, coming from driving a manual car I find some of the the gear changes a bit funny like I am riding the clutch badly (if it were a manual). This is most noticable in changing from second to third gear, where if I put my foot even just slightly down after the change the tacho revs up and then revs down and then revs up again, over a period of about 2-3 seconds. Acceleration seems hampered. It seems better if I keep the accelerator still.

Is this normal or is there possible something wrong with my car ? Is there a new driving style I should adopt ? I will ask my dealer but I'd like to hear other opinions. Sometimes I think I am driving an Airbus plane, which has computer control, and I have heard the most common common from pilots in the voice recordings is "what is it doing now ?".

2 weeks ago i started to feel funny driving conditions on my 2004 545. To my surprise...i searched around on the net...and found you have very simiral problems. My car off the start will rev up to 3000 rpms...but i feel no punch...as if there is a horsepower thief in my car. I'll let go of the gas pedal...and the RPMs will just stay up there for another second. Its a very wierd feeling. I'm just not getting the "throw you back in your seat feeling" I would get when i first got the car. (now have 4400 miles on it).
Some other members posted it might be a throttle issue. Well this car throttle-less. It has a new Valvtronic system similar to the 745.(same engine). Neverthe less...I'm not happy.
Am working with my service dept. to pinpoint the problem ...if any.
One more thing...read a review ...here is the portion of it:

Follow-Up Test: 2004 BMW 545i
Performance at a Cost

......The driving experience ranged from irritating to exhilarating. Irritation came quickly in low-speed traffic, as the drivetrain responded unpredictably to accelerator pedal input. Too little pressure and the sedan would move out sluggishly. Too much and it would surge forth, leaving the driver to rein it in before it snuggled up to an SUV's rear bumper. The area between these extremes often eluded our editors and made the car a pain to drive at rush hour. In addition, one editor noted that the transmission tended to hang onto first gear too long in these situations — eliciting more thrust than you really want when slogging from stoplight to stoplight.

Hi,
I notice some wierd behaviour with my 2005 530i since I bought it.
When going downhill on a somewhat steep hill, I either keep the
brake pedal slightly pressed or I pulse it to control my speed.
While my foot is busy with brake pedal, the rpms starts to rev up
upto 5000rpm. It feels like car is trying to accelerate while
I am trying to slow down. This behaviour stops when speed is reduced to 30 or so.
This only happens when braking on a downhill not on level road.
If anyone knows about this please let me know.

Local dealer guys called me and explained
that is is normal BMW-designed-for-performance
behaviour. Several other models have the feature.
Raised revs due to auto engine braking on downhill enable
faster re-acceleration when coming out of the downhill
slope. The car indirectly detects that it is moving downhill
when gas pedal is not pressed and checking velocity.

I bought a 545 with Steptronic in March of 2005 and have the same problem, along with others, from day one. I'm getting no where with the 2 dealerships I've tried so far. They are never able to reproduce the problem. They apply program upgrade after program upgrade, which always messes up something else, like navigation or bluetooth.

What's worse, is I can add another complaint, which is worse than all of this. On acceleration, the car will sometimes rev way up, without engaging the transmission, and then slam into action so fast that it feals like being hit from behind. It is life-threateningly dangerous, because when it happens it is such a shock you are distracted from driving. It normally happens from a standstill, but has happened on the freeway as I was trying to move from a slow lane to a faster lane. When it slams, the natural tendency is to let of the gas, however, there was faster traffic approaching from the rear, and I almost got hit.

Has anyone seen solutions to the original post's issues, or has anyone exprienced this one and found a solution?

I have had it in approximately 5 times for the same problem. I keep all my service documentation, so I have collected it and have referrals to 3 lemon law attorneys and an independent BMW mechanic, who I am about to turn to help me get rid of this life threatening piece of crap. It is my 3rd BMW and I thought for sure I would be a BMW fan for life, but this experience is doing me in.

I'm going to post the following in another thread, because it seems more common, but the other problem I have is repeated excessive wear on the inside left rear tire. I'm putting my second set of tires on at 16,000 miles, after replacing the first set at 4,000 just because they road poorly. The repair notes state that they noticed excessive wear back in mid 2005.

believe it or not this is a somewhat common problem... I know there are a lot of really really BAD Cali dealers out there.. so i'll post some BMW SIB's for you to take into your dealer.. this is a very known issue and i have started the Lemon Law process too... my car for the most part is almost fixed... but the problem is the tranny has been BANGING for 2 years!!!! what will happen once this is out of warranty?

From all the reasearch that i've done.. i've narrowed it down to 2005 645's(should apply to you to... same engine) that were built in late 2004 timeframe.. whats your build date? it's on the door jam

But since i bought the car used.. AND it's still under BMW warranty i can only do "breach of contract" and get compensation back from BMW.


Also i've definatly read about excessive wear on tires on 5ers ... start searching this forum

We just lucked out and bought late 04 builds... any later build dates and i think we would have NO complaints.. we just lucked out.

It turns out the build date on this car is Febrary of 2005. So the '05s are still having the problem. Since my post, I have had the "Bang" happen again twice and replaced the rear tires. The alignment is really bad in my opinion, but within BMW specs. I'm having a friend's race mechanic, with all the proper equipment do an alignment clearly documenting before and after specifications, because I can't wait for BMW to pull their heads...

Anyway, I have completed collecting all of the service documents and would appreicate any additional information you might share, so I can hand this off to a good attorney. I'm tired of wasting my time on this car. Its too bad, because I'd absolutely love the car if it wasn't for these issues.

Don't waist your time with alignments or having friends look at it... it's a software issue with the car... PERIOD!! after i got the "special laptop" to reprogram my car the HORRIFIC bang went away.... but in turn they added some sort of hesitation to it. Hard to explain... but don't get anything aligned or looked at, it's just a waist of time.

FIRST SIB is 24 03 05 software update for transmssion?

And the second time the special laptop was sent from BMWNA... PUMA case #5980839

this is a known issue... and if your local dealership did even 2 minutes of research... they would have done these things.. My SA called me within an hour and told me there are SIB's and PUMA's out there for tranny bang!!!! You should also be pissed with your local dealer and hand them these numbers then smack them in their face.


oh yea... lemon law lawyers are free.. and get their fees paid by BMW..

But the info above are the 2 main tranny bang issues bmw has logged.

My lawyer also suggested I no longer waste any time on this car. During one of the 6 attempts at repairing this thing, PUMA brought out a laptop as well and loaded a software fix. After they did, I too had the hesitation "feature". Basically, they took away performance, to cover up their defect.

The case is being put togther right now. I selected a lawyer that was referred by a lawyer that actually defends Porsche and BMW on the other side. Supposedly a good lawyer, but we'll see. I'm just tired of dealing with this thing. If successful, I just don't know if I'll ever buy another BMW.

Thanks for your help. I will forward these numbers to my lawyer.

i'm glad your not the only one who noticed the car got "slower" after the special laptop!!! and sometimes there is a slight hesitation when i press the gas.. it's messed up. Let me know if you settle or go to court... I filed my paperwork about a month ago.. it's probably a 3 month process in total i'm guessing. Send me a PM if ya want.

The hard part is i still love the car... BUT what do you get next? i don't want to "trade down" ... but i do know newer bmws don't have this tranny bang. Thank goodness this is all covered under the warranty!! thats the good part..

Do you have scans of the SIB, which shows BMW's description of the symptoms? I have a 2005 545i automatic. Build date was 02/05, I purchased (leased) in 10/05.

I was just in the shop for some other stuff, and mentioned this issue to them, as well.

Here are my symptoms:

1 -- I have slight hesitation when leaving from a full stop using normal acceleration., then it "kicks in" to as I get underway in 1st. This all happens in a matter milliseconds, but is definitely noticeable.
2 -- Sometimes I get a harsh shift from 1st to 2nd, when leaving from a full stop using normal acceleration. This mostly happens in the first 5-10 mins as I leave the house. But I have 3-4 stop signs or lights between my house and the highway, so I really notice it at those lights before I get on the highway.
3 -- I've had the uncontrollable "lurching" as slow speeds. This is very rare, but very scary. One example was when I was leaving from the Taco bell drive thru window. I was almost coasting, and as I applied gentle gas to round the building it starting an uncontrollable lurching. To passersby, I must have looked like an idiot driving a clutch for the first time. It was that bad. Since then it's maybe happened a few more times.

I thought #1 and #3 were related to something I may have done, or cold starts, etc. They looked into #2 and found nothing.

Since taking delivery, the car has been in the shop a couple times for minor stuff. Two of those visits included getting upgraded to the latest iDrive software. Not sure if this is the same software you're talking about.

Thanks for any scans or other official BMW info you can share with me which may help me state my case more clearly to the dealer. But, then again, I don't really want to give up performance, either. My options may be more limited on a lease vehicle than the scenarios you're pursuing with lemon laws, etc.

Cheers,

Sounds pretty typical that they would blame all of this on you. That makes it easy to not do right by their customers. I have all the same stuff happening that you mention, so I guess we both should take driving lessons!

As for the Lemon Law approach, it doesn't matter if it is leased or owned. In California anyway, if you have had the vehicle in for the same significant problem 3 or more times within the first year or 18,000 miles, you can consider demanding remedy under the law. Mine is leased as well and I've been in 6 times for the same issue in about 18,000 miles.

My attorney is pulling all the SIRs, etc. I'll ask for a copy and send them your way.

Did anyone ever discover a remedy to this problem? I have a 2005 545i with Steptronic and this issue is driving me crazy! My passengers thing I'm getting cute with my take-offs, but I swear all I want is a nice smooth acceleration from a stop. A recent 325xi I drove as a loaner was 10x as smooth as my 5 has ever been.

I have CIP/PROGMAN v24.xx, so I guess there's no software update that will fix this. Could someone please end this piece of misery from an otherwise brilliant automobile? :bawling:

I didn't realize that was still an issue since I have had my 06 530xi for almost 2 years now and after the first couple of months this clunk finally went away. I hope BMW has resolved this.

I should clarify: I don't experience the tranny slam. The hesitation and then catching at launch is what's getting my goat. Please tell me there's a remedy for this very annoying problem.

Does it happen all the time, or intermittently?

Do you notice that as you slow down, and vehicle
shifts from - let's say third to second, or second to first -
that the tach increases and you pick up speed for
a bit, before you decelerate further, which might explain
why you feel the lurch?

I have an '05 545, and I have experienced this issue on several occassions. It typically occurs when I'm at low speeds, switching from 3rd to 2nd or 2nd to first, especially slowing down for uphill driving. It feels as though somone has rear-ended you, the 'clunk' is that bad.

I haven't experienced it in the past 5k miles, and my dealer claims that all is fine.

This sounds like the transmission slam that was so prevelant until recently. It was apparently fixed in a recent CIP version (20.xx, I think?) and is no longer an issue. When was the last time your car's software was updated? It may have been fixed then.

Makes sense, I think my software was last updated about 5k miles ago at its major service.

That transmission "stickyness" was awful, I remember my passengers on several occassions asking if someone ran into us when it happened. Thanks goodness it's been fixed!

OK, so several people are experiencing the launch hesitation (different issue from transmission slam), but nobody has been able to get it corrected? Does BMW expect us all just to live with the fact that we have to switch to manual mode to take off smoothly from a stop?!? :cry: :thumbdwn: :dunno:

Ok, so in addition to my original concern, just today I noticed that when I come to a complete stop, the car makes a "thunk" sound. It sounds as though something is dropping. I'm assuming it's when the car shifts back to 1st gear. Off to service!

Anyone experience something similar?

Hello, everybody, I'm visiting from the E46 board and I'd like to make a few observations.

After reading the threads listing naughty automatic transmission behavior across mileage figures ranging from basically new to high mileage, I believe BMW has some serious powertrain software revisions to do.

Reading about unnecessary downshifts, lagging throttle inputs, and unpredictable gearshifting in general, I believe these transmissions, left alone, not reprpgrammed, will reward their drivers with some serious premature transmission failure.

It simply isn't good for an auto trannie car to be pulling so many rough up and down shifts during a normal driving cycle, ie. I'm just trying to get to work but my car acts like it's staging up for a lap of the Nurburgring.

From what I have read BMW and its' dealers appear to be stonewalling most drivers complaining of this problem. Uh, that's a no no in the $50 to $60K price range vehicle spectrum!!!

Toyota had a simular situation several years back with the problem being engines sludging up and failing. Many of those owners had their cars serviced at the dealers right on recommended schedule, yet Toyota chose to deny warranty claims and only repair the cars on the customers dime, citing maintenance neglect. It was all documented in Automotive News and others, just google it and find out for yourself.

Toyota owners rebelled and by setting up a website along the lines of www my lousy sludged up toyota .com they began to see the breadth and depth of the situation.

Soon the site was loaded with hits stating things like "well this is my last Toyota" .

After a while Toyota came clean and handled the situation properly.

Perhaps that needs to happen in your case....www my lousy shifting 5 series .com and ask posters for name and serial # only. Provde links to the site on other enthusiast sites and see what happens..might be suprising!! Cheeers!

I have to agree, I have experienced this about 5 or 6 times and have 52k on my car now.
I too mentioned it to by advisors and they claim nothing is wrong.
I can't believe this is not a TSB or even a class action suit, my concern is how this loud and harsh clunk is normal and am sure it is affecting the life of the transmission.
Makes you wonder why BMW can't figure out this problem. I have had half a dozen other cars / brands and none had tranmission clunking like this.

I have the slam too!!! '05 545 not sure of the build date as it is been at the dealer for the last three days and I got a lovely Kia to drive. I complained twice before but they told me it was normal. This time they finally admitted they experienced the slam on a test drive. Now they are waiting for permission from BMW to reprogram the transmission.

I really love this car but the sensation of getting hit from behind needs to stop.

I simply can't believe this is still happenning. I too complained about this over 2 years ago for my 06 530xi, but the problem eventually went away after several months, but that was still unacceptable for a incredible new vehicle like the 5 series. I was convinced somewhat that the car was learning as some of my fellow members on her mentioned, but now that just sounds wacky.

My brother 04 545i did not have this problem and my old 01 530i never had this problem and just recently my 08 550i has not experienced this issue. Hopefully it was fixed on the new cars or maybe it's not as common on the 8 Cylinder engines. Who knows?

Drew,

I purchased an '05 545 with a build date of 10/04 this past April. I would not describe my problem as a slam but rather a significant hesitation when accelerating at low speeds as well as a severe jerking, transmission slip?, that gave the sensation of being on a bucking horse. The car was in the shop for 4 days while they ran numerous diagnostics and potential fixes before finally getting permission from BMW to reprogram the transmission. The transmission is now as smooth as butter and it has been 7 weeks without any problems so I am hopeful the problem has been permanently resolved. Now all that is left to make this a dream car is replace the horrible run flats with Michelin PS2's and maybe new 166 rims.

As I was surfing looking for an issue, I realized that this problem has existed for some time. I have a 2008 550i and I started to experience this annoying coasting jolt about 4-5 months after purchase. The jolt seems to be most profound when the engine is cold and tends to quiten or become less intense as the engine gets warmed up. I feel like I've been hit from behind. So frustrating to experience this with a premium car.

Mine did something similar, although only during a rolling stop/start

Dealer reprogrammed and it went away. There is a TSB on this and your dealer should know about it.

Sorry to revive an old thread, but hey better than a new one?

Is anyone else still having this problem. The transmission clunk is so violent, I feel like I am being hit from the rear. This mainly happens during rolling stop start situations, (i.e. 4 cars in line at a stop sign.) What is the SIB covering this problem? My dealership hasn't been able to replicate this problem, as well as many other issues, like damaging my car EVERY time it has been in their shop, but that is a whole different issue. I will be trying a new service center to attempt to solve this problem. Hopefully it can be resolved before I go into my CPO this june. My dealer claims that my transmission program is up to date. This problem started after an alignment (active steering,) and tire replacement.

Thanks

Thanks as well, I had software updated before the winter to try and fix this and it did it again. Only very occasionally, seems like the situation has to be just right, coasting towards a stop, red light, then adding power, light turns green before I actually stop, and WHAM it feels like someone rear ended me.

If it happens again I will take the SIB to the dealer.

Thanks again

I am having the same problem with my '05 545 that I just bought with only 27000 kms - happens only in MS mode, uner the conditions stated in the SIB. With a little carefull coice of when to use/not use MS mode, I can avoid the problem so far. I will try to get into the dealer in the next couple of weeks. Hopefully I can find this thread agian & update it. Seems it is a really common problem, kind of like my '03 540 with the leaky door seals, valve cover gaskets, radiator failure, etc,. Traded it in as soon as the CPO expired. If the Japanese ever figure out how to make a car drive like a BMW and be as reliable as a Lexus.....

Thanks for the SIB, hop it works
