I had them take mine out because I refused to pay $200 for 1 sensor for my spare tire.. Apparantly the sensor was missing from the spare wheel and they did not want to replace it for me under warranty so I said take it out then...

so you took the sensors out or the whole "progrem" so you can run it with out sensors and not get the light?

i got all four my sensors replaced and the control module for the tpm replaced under waranty bout month ago the batteries inside the sensors were low so they replaced them i didnt even get the chech tire pressure light they must have scanned it and told me the ordered the parts.

National Highway Traffic Safety Administration (NHTSA) regulations on TPMS:

By 9/07, all vehicles must utilize a direct monitoring system with a pressure sensor inside each tire to broadcast the tire pressure to a central receiver on the vehicle.

The yellow tell-tale must illuminate during the NHTSA required test within 20 minutes when there is a 25% loss in tire pressure (any or all of four tires).

I guess this means jail time to those who remove this system that falls within the regulation guidelines.As for prior vehicles,Im sure there is a way to remove or disable the system.I haven't performed a reverse retrofit and with software updates,there are changes we aren't aware of until discovered.By now perhaps it cannot be removed from the Vehicle Order because its not a retrofit option in the US Market.Perhaps an "enable" or "disable" selection (iDrive) is in order for older vehicles not affected by the new regulations.Who knows? They might be listening.

BMW Tech i had a wierd experince every time i kickdown and it happen to be little bumps on the street , i hear slamin like my shocks are out and even feel shaking underneath the car and on the arm rest like somthing hits me for the bottom ? what would that be??? any one know BMW_tech Your advice is greatly appreciated

Okay,you're driving along and you floor the accelerator pedal.You hear a "clunk" and you feel the whole car vibrate. Am I correct so far ? There arent any warning lamps illuminated and the problem no longer occurs ?

I think your problem may be the U-Joint.A deterioration or separation of the rubber in the universal joint located between the transmission and drive shaft assembly can cause clunking (during load reversal) or sometimes feel like being rear-ended (perhaps).Either way,I suggest taking it in for visual inspection of all your suspension components.The only way to determine if the noise is caused by a defective universal joint,the driveshaft must be removed from the vehicle. Once removed the metal collars can be checked for looseness or separation from the rubber material.Make sure they clear the adaptation values if they replaced the U-Joint.Vehicles produced from 10/22/2002 up to 3/2005 can be affected.

BMW Tech - do you give relationship advice too?

thats exactly what happens not that i loose taraction and the triangle thing illuminates, but you know i tell that to the dealer , cant duplicate problem sir, is there a way you can say it so i can explain it to my SA cuz you know if they can't replicate bassically they would say its normal

SITUATION
One or more of the following complaints may be received from the customer while driving slowly, coming to a stop or at highway speeds:

A clunk can be heard while rolling slowly and downshifting from 2nd to 1st gear coming to a stop.

Load reversal causes a slight clunk noise.

A clunk noise can be heard while shifting into forward or reverse gear from park or neutral

haha. not yet. i think i may have found the perfect girl though. shes 20 and drives an 06 750Li.

Id watch her closely.She spells trouble.A 20 year old chick driving one of these has got a lot of baggage in tow.Be cautious and take baby steps before you find yourself in a situation where the only way out would be the most embarrassing moment in your life.If you can't be yourself around this chick,you might as well find a chick at a MUNI or BART station.Theres a whole lot more to a natural and unpredictable woman.

bmw_tech when BMW replaces the tranny what else is replaced. for example do they replace the torque converter ect....

New tranny comes with a new torque converter.That's pretty much it.Depending on the condition of the fluid in the old transmission,most technicians do not clear the fluid contained in the cooler lines.I make it a habit to do so,regardless of the fluid condition.Since the guibo (or U-Joint) is a big issue on these vehicles,I would double check the part number and its integrity.If questionable,I would throw a new one on since there really isn't any extra labor involved.I would update the PuMA case and get authorization to replace the coupler (granted it hasn't been replaced and vehicle production falls within known affected vehicles). Other than that,the programming and clearing the adaptations would truly define "remanufactured" parts as NEW and IMPROVED.

I have ran across 2 X5's with the ZF Transmission where after installing the "new" transmission,all I had was reverse gear and I had to do it all over again.When I reported the transmission serial number,all I got from the liason/engineering dude was OOPS.I wasn't going to complain unless they didn't pay me twice.The other transmission I knew was bad because it looked like it was dropped from an airplane without a chute.The box was missing and the pallet was reduced to one slab of wood barely hanging on to the oil pan.

off the topic tech but other than the forklift what kind of car do u drive. in all honesty, would you recommend an e65/e66 to say - a family member. plead the 5th if you feel your job is in jeopardy.

Don't I seem like an honest guy ? I wouldn't recommend it to a family member simply because I would end up responsible for it's maintenance.They wouldn't pay extra for the maintenance plan as long as Im around.To the tech savvy and a buddy that likes the finest things in life,I would recommend it along with the maintenance plan unless he knows what to do with a wrench and a ratchet (and the difference between the two).I on the other hand,prefer the simple things in life.I drive an E36 M3 sedan with auto trans (same tranny on the E-34 530iA).I dont like to shift in traffic (bay area),I don't like to adjust my valves,I dont like seeing my car on a rack except for routine maintenance.Perhaps I could find an E-39 M5 to my liking with a pricetag I can afford.I prefer the E-38 sport package (with all the bells and whistles including the active seats) over the E-65/66 eventhough these newer generation vehicles are far superior in every way.I've had "ricers" in the past,I wouldn't deny that.The only action I seem to get on the highways are California Highway Patrol vehicles.I can't seem to shake them off my tail everytime.I guess thats impossible if the diameter of your tailpipe is similar to the size of your wheels.I can't help but giggle everytime one of those pulls up along side me,I simply turn up my radio and get as far away possible as quickly as I can.If I were to put them in order,1 being the one I like most....:

1) E-60
2) E-65/66
3) E-90/92
4) E-64

How's that for honesty man ??

thats good man... i wish i could see my car only on the rack for routine maintenance..... lets see some pic's of your ride.

honest as they come. personally, i think they should be paying you OT for putting in work on this forum. i'm thinkin' every member of this forum should donate to the "get BMW tech in an M5 cause". I got 5 on it. (dollars not thousand)

man don't make me laugh.If my fillings happen to come apart it's going to cost me more than what you are going to give.Someday I hope to be able to sit down and have a beer with y'all.That's enough for a little good deed that everyone always seem to notice.My car isn't for show sunny_j.It looks like my grandpa,the grilles are missing along with splash shields (no front teeth)/dirty/and all panels are wrinkled.But the radio and engine sounds good.Every turn of the key guarantees a completed journey.As the great Marley said,my feet is my only carriage so I've got to push on through.

I have been blessed to have worked (and continue to work) on the 2 best car line any kid could have imagined.Ferrari and BMW.My interest in having a nice car just disappeared when I became a single dad.My interests are what keeps her happy.If she asks me for an E-65,I might just give in.

BMW Tech,

Would you happen to have the SIB # for the issue regarding the crackling sound in the speakers for the E6xs? My speakers do this occasionally but when I bring it to my dealer, they NPF me b/c the issue doesnt surface itself. Maybe with the SIB #, I can assist my dealer a little

thanks.

What I would suggest is setting up an appointment to where you have spare time and wait for the vehicle.Knowing they may CND/NFF/NPF,they should run a fault survey.If there aren't any faults stored in any MOST bus module or MOST system analysis there isn't anything they can do.Intermittent problems are difficult to diagnose most especially when there aren't any errors or faults reported.Another factor that shouldn't be overlooked are faults related to battery voltage issues that the PM (power module) monitors.If they find something wrong and they don't have a loaner vehicle for you,reschedule.If no problem was found again,ask to see the diagnosis report and obtain a copy if possible.You need to pay close attention to wether or not they performed the neccessary diagnostic test plans from beginning to end.Mention it to the service advisor that if NPF was the verdict,you would like to see the diagnosis report.Use the search feature,Im sure I have tackled this particular issue on several threads.It's a toss up between AMP (LOGIC 7) or M-ASK (in-dash radio unit) and possibly TCU internal problems.

Hate to sound like a noob, but what does these acronyms mean: CND/NFF/NPF, TCU. I am currently having problems 14 days into ownership and I was told they are not able to find what my issues are. The only thing they did was say that I have AGM Battery??? and the car had to be recalibrated for it, and the Tow Manage Control Unit was disabled????.

There were low voltage faults found, but no trans faults which is what the car said to me and shut me down on the side of the road.

They took out the sensors and the Program so that I dont get any warnings...

First off,my apologies to all for my absence.Ill do my best to get back here just like before.I just had to decide wether or not to leave my current employer.Im staying put.

CND-cannot duplicate
NFF-No Fault Found
NPF-No Problem Found
TCU-Telematics Control Unit which you referred to as Tow Manage Control Unit

Battery State of Health and Charge could cause all these problems.By disabling the TCU,it prevents it from waking up in order to transmit data and check whatever data it needs in order to operate/transmit.Since you don't have an active Assist contract,it is disabled.See my posting on AGM battery for information/clarification.

^^ im telling you open up a shop up here.

any idea's why this is happening? could it be the cold weather because it barely gets over freezing here.

Hi Sunny_J,

I got the same error, disappeared the next day
