How would this not be under warranty? Are they trying to say that you are past 3/31? That's poor.

Agreed, let's see what they say today. Basically they are saying that there are no fault codes, and I said I agree but the long cranks and stuttering is there, and they confirmed it was. I showed them my email (twice) that I had sent prior to warranty expiration.

That's dumb. It's like saying the Weather Channel says it's not raining. But there's water pouring out of the sky.

Now I have now had two of these malfunctions. The first one resolved itself. We will see about the second one... Each time it has happened just after service. So iI just should never get it serviced. (NB. They have to repair it first)

I have a 2011 750LI. I have just experiences the 5th Drivetrain Malfunction today minutes after getting it out of the shop. I have had all the fuel injectors replaced, the low pressure fuel pump, spark plugs, coils, etc and it is still not fixed.

I do not think BMW can fix this car. This is a widespread problem (confirmed by my local BMW service advisor) that needs to be addressed in a definitive way. I am now looking for avenues of recourse and would be interested in what others have accomplished.

I had 4 drivetrain malfunctions on my old 7. Got a lawyer and got BMW to buy it back for what I paid minus a small mileage fee. California's lemon law however is the strongest in the nation. Good luck.

First off, I hope that everything works out for you. I just had my first experience with the "drivetrain malfunction" this week. I've now had both banks of fuel injectors, plugs, and the high-pressure fuel pump replaced as well. The tech also found a leak in a cracked air hose.

My car is a 2011 750Li with only 18,670 miles on it. Bought it in early June as CPO with only 14,800 on it. Thankfully the service I've received at my local dealer has been excellent.

This is clearly an issue for BMW and I've had discussions with Service Advisors at both of the BMW dealerships in the Twin Cities that have confirmed it. Nevertheless, because the matters have been dealt with under warranty, I've managed to let go of the frustration and still look for any reason to go out for a drive.

It is a 2011. It now has 56k on it. I bought it with 24k on the car. The problems have been surfacing over the past 20k+ miles.

I now await for a fuel injector to replace the one that failed. They have been very considerate and have given me a loaner until my car is repaired. I hope this is not a recurring problem like it appears to be for so many.

I hate to be the bearer of bad news but this all points to the infamous and now common: Bad Fuel Injectors!

I have a 2009 750Li that has 100,000 miles on it. I am the second owner. The service writer said that every fuel injector has been replaced at some point. I was coming home the other day and went to pass a car on a two lane highway. As soon as I punched the gas, it took off and then shut down on me with a Driver Train Malfunction. It would not go into passing gear after that. It slowly got up to about 75 mph. I decided to pull over at the next small town. Right before the car came to a stop it started shaking like it was running out of gas. I immediately turned it off and waited about 10 seconds and restarted. Good as new! I am not sure what happened but ever since, the car has a hard shift from 2nd to 1st gear. But it doesn't do it every time. I am taking it to the dealer in the morning. I have an extended warranty from my Credit Union when I financed. I am seriously thinking of selling it. I just had the Valve stem seals replaced because it was using a quart of oil very 1,000 miles. No smoke, no leaks before the repair. The fix didn't help much. Be prepared to buy lots of oil.

Angry 09' 750i "Major Drive train Malfunction"

Ok ~ So for my 4th or 5th luxury car I bought a 2009 BMW 750i with 66,000 miles. It still has the temporary plates and so far;

New Battery
Two New Rear Tires
Major service recall (two weeks to replace a timing chain gear)
and oh, by the way... you need to valve guides $1750.00

Two weeks later = Check engine light.

A week later = "Major Drive train Malfunction" (the first time I tried to take the car to the mountains) 40% power, shaking and running like a bad diesel... cleared itself BUT I don't trust the car now!

It's now in the shop, they're suspecting some sort of "fuel issue", but after reading the forums, it looks like there have been multiple "diagnoses" of this warning message, and many, many of them have been ongoing.

I've owned a brand new 335i that had the fuel pump replaced twice, and towed once in a two year lease... and a 5 series that was really reliable.

I've owned a E55, ML350, S500, E350 all with ZERO problems...

Should I dump this 7 series now?

Read up on the CCP and get the dealer to perform this campaign for you(free of charge). Hopefully it will address your issues - I wouldn't spend a dime on repairs until that is completed.

There are thousand of posts on this very forum about it - N63 CCP

Sounds like he's already had it done. Said his car was in the dealer for two weeks getting a timing chain.

You're correct... it may have already been done?, here is what my service receipt says from April 1st;

Performed visual inspection of all components. Found fuel injectors to be index 12. Found that the updated low pressure fuel pipe with updated sensor had already been installed. Removed and replaced vacuum pump, and all crankcase vent lines. Removed and replaced both mass air meters. Found both oxygen sensor brackets broken. Replaced both brackets. Found both intake tubes cracked. Replaced both intake tubes. Cleaned residual oil from engine, Performed Road Test.

Engine failed to pass the timing chain check through ISID tester. Per TC approval, removed engine from the vehicle. Removed all components from engine to get engine down to bare block. removed and replaced both timing chains, and all guides. Removed and replaced sprocket on the crankshaft as described in the repair instructions. Re-installed all removed components, filled and bled cooling system. Filled crankcase with oil. Cleared faults. Started and ran engine to operating temperature. Performed extended road test (30 min.). No further issues.

Removed and replaced valve guide seals (at my cost) and performed a carbon blast, goodwill.

**After I got the car back, about every 20th stop at a red light, it had a slight rough idle, not severe, but noticeable, and then the check engine light came on. I called service and set an appointment, but then the light went off... service recommended I bring the vehicle in anyway, and in the 3-4 days before my service appointment "Major Drive train Malfunction" issue with check engine light, super rough 40% power, triangle warning light.

Thanks everyone for your comments and sharing your expertise

My question is this? Out of all of you who have had the drivetrain malfunction light come on, who actually ever got it resolved?

I had the customer care package performed. Got it back and boom! Shut down at the red light in 5pm traffic. Drivetrain malfunction light and then the fuel problem message. I could get it to barely start but it would immediately shut down when I out it in gear. Finally got it off the road, called a tow truck, called a ride, called the service manager. I was not happy. Finally after 15-20 minutes the car cranked up and ran perfect. Had to call and cancel all the rescue vehicles coming to my aid.

I've driven the car a few times here and there to see if it was going to happen again and nothing happened. Today I decided to do a 100 mile trip to a neighboring city to look at a job. Ran fine all the way there. Got off the interstate and four or five red lights later....car cuts off, drivetrain malfunction and then fuel delivery (or something about fuel) message. Car wouldn't even stay running for 5 seconds before cutting off. Waited 15-20 minutes and presto, no issues. CEL goes out after a few miles and everything is fine.

What the hell is causing this? I don't trust this car to go to the store and back and definitely don't want to have anyone riding with me in case it breaks down.

So again, anyone have an actual cure from BMW that they can verify has fixed this problem? I have read a lot of post where people complain about the problem but after they get their car fixed I guess they don't bother updating any of us..update us please!

Thanks.

Update

The dealer kept my car for about 3-4 days... they were working with engineers at BMW, who are "following this problems / these issues closely" Got my vehicle back from the dealer yesterday, and here is what the service ticket said;

Connected battery charger. Performed short test. During first short test , only fault stored in the DME was an internal check sum fault. per test plan, deleted fault memory. Shop foreman O'Mara submitted puma case 61350322. Per puma response, smoke testes complete intake system. removed all spark plugs, and performed a visual inspection. Checked injector calibration in the DME. Checked fuel quality. All were good, and within specs. Re-installed all removed components. Performed road test. SES light came on, and the vehicle went into safe mode. Performed short test. Found misfire fault stored for cylinder 3. Per shop foreman, removed and replaced speak plug for cylinder 3. Cleared faults. Performed road test. SES light came back on. Performed short test. Found misfire fault stored for cylinder 8. Per shop foremen, removed and replaced the spark plug for cylinder 8. Cleared faults. Performed multiple extended road tests. SES light did not return. No further issues.

(my thought is... if the entire engine was just stripped to the block in my previous visit... wouldn't they have replaced all the spark plugs when the motor was put back together? also, why are they charging my battery? they sold me a new battery on my first visit to the dealership about 60 days ago? I'll have to say it's awesome having my car back after driving a 3 series and 5 series loaner... but I'm very, very hesitant to drive it any distance from the city)

DRIVETRAIN MALFUNCTION, within 50 miles of release from service!

My prediction was correct... I picked up my vehicle from Murray BMW (Denver, CO) yesterday and the same "Drivetrain Malfunction" happened today! Left my service manager a message at 1:00 and no call back yet... 6:31 p.m. in the evening.

So they have to "charge the battery" whenever they run diagnostics on it so it doesn't discharge. That's normal.

Regarding your other issues, you probably wouldn't have had any of these issues if you didn't perform the CCP. I guarantee you it's something the dealer is (or is not) doing (read: competency, maybe they haven't done enough of these and messed something else up). Look at a youtube vid of what is required to change the timing belt, frankly, unless it's a BMW trained ASE certified Senior level tech.. I don't know how ANYONE else could do that job w/o forgetting or messing something up.

EDIT: oh and unless a part is failed or part of the CCP, they would reuse it (like your sparkplugs). That's pretty normal. But if the sparkplugs got damaged (say the gap got out of whack) I can see where it might cause issues.

Thanks for your reply ~ any additional feedback / recommendations are appreciated... who knew that a "recommended service" should not be done! Yikes.

Just thinking now I need to get rid of this vehicle... it's sad because it's magnificent!, but if it can't be trusted to get from point a to point b, let alone take a road trip (to really enjoy the vehicle), it's pretty much worthless. The question becomes, how do I in good conscious sell or trade the vehicle with this on-going issue.

1. I can't even believe BMW allows this issue to continue without drastic resolution... a complete motor replacement or buyback.
2. I can't believe there has not been a class action lawsuit over this issue.

Probably because it's not a problem with the car, but maybe the dealership that did the work (there are many folks that have had CCP done w/o incident, but of course many also that have. This inconsistency leads me to believe that the only variable between the two would be the human variable. As all the parts that are being replaced and the process to do so are usually set in stone and don't have any differences between one part or another or one procedure or another). This is something BMW corp and engineers have no control over.
