Third issue with only 9k miles...Drivetrain Malfunction

BIMMERPOST
     Featured on BIMMERPOST.com
I know this error is somewhat common but I recently had an issue with a Chassis Malfunction error. Would go away once I restarted the car. Dealer confirmed the error but could find no issues so they just cleared the log and gave me the car back.

Two months later the Chassis Malfunction error returned (would still go away after restarting) and they replaced the right acceleration sensor, cleared the error and gave it back to me.

Today the Drivetrain Malfunction warning went off on my way to work and the car entered limp mode. Turned it off and back on at a stoplight and error went away.

The car certainly has some "personality" but it is rather annoying to have these little issues. In the six months I've owned my car, it's had more problems than my Infiniti which I had for six years with no problems.

It seems obvious that there seems to be no actual mechanical issue. I'll probably wait until I'm due for an oil change to have them look at it and refuse to pick up the car until a resolution is found (simply clearing the error log won't cut it). I can't help but think there's a larger problem here that's causing these seemingly false errors.

I like the car and all but it's been, by far and large, the most unreliable car I've ever owned and it's only been 6 months.

Sorry to hear that man, not what you'd expect from a $50K+ car. But I wonder what could be causing these malfunctions and if it's limited strictly to the F30. I've had my 435 for 6 months as well and I haven't had a single malfunction at all (other than having to add a quart of oil)
If it's only software related, BMW needs to straighten this out asap.

Happened to me before so at third time, my SA called the guy from BMW factory and end up replacing the DME.

Now, I have new media code with minor change layout on the system. It looks like i have Mini Cooper software- MN-002.045.001

I think my SA did the right thing by calling the factory guy and have the expert check thoroughly. Downside was..dealer had the car for 4 weeks

Yeah that sucks too, but I'd rather that if that means finding a resolution to the issue.

I hope you are successful with that.

I've been on the other side of intermittent problems like this (not cars, but control systems & sensors can't tell the difference).
When you can't figure it out, and all the resources in your company can't figure it out and the people who manufactured and designed the durn stuff can't figure it out, then three things happen:
1. You long for the good old days when a car (or whatever) was a car & the only computers were in the offices.
2. You apologize a lot, bosses, customers, etc etc.
3. There are only so many parts, so you start parts swapping.

The approach folks most often want to take is to swap 1 part at a time until things go your way.

The 'really want to make this guys life better' approach is to swap several things & then try to understand the problem after your car is fixed.

Were I you I'd be looking to push for a shotgun fix it approach, else I could see them really taking a long time unless they just get lucky and guess the right part.

Great suggestion and one that I'm definitely leaning towards since the issue, while not crippling since the car still drives fine, is pretty annoying.

I'll keep you all posted.

I've had that same issue, and it was a failing auxiliary cooling fan. Apparently one of BMW's suppliers sent out a batch of less-than-optimal quality units. They go behind the auxiliary radiator in the lower part of the front bumper. Not sure if the fan completely fails or the DME gets a bad signal from it. Takes a day at the dealership to replace, fixes the problem.

Short answer is no.

Long answer is also no but with an explanation of why.

Just got a call from the dealer. They believed that the reason this was happening was because I have F235/45/18 and R245/45/18 winter tires. It does have a slightly different ratio...

Bridgestone S001RFT (OEM Summer)

225/45R18 25.9"
255/40R18 26.0"

Ratio: .9961538

Michelin X-Ice Xi3 (Winter Tires)

235/45R18 26.3"
245/45R18 26.6"

Ratio: .9887218

1- (.9961538/.9887218) ~ 0.91% difference in ratio

...less than 1% difference would not strike me as causing a Drivetrain Malfunction light to come up.


Now they did say that there was a fault code with the fuel rail sensor and the transmission was leaking fluid...

225/45-18 is 25.9
245/45-18 is 26.6

Ratio is .97368421.

1.02% difference, which is more than enough to screw with xDrive

That is a really stupid answer by your dealer! But it doesn't surprise me... In Italy they are the same...

Fortunately, I have the RWD model. I definitely would not alter overall diameters and ratios if I had an AWD. (I did have a Subaru in the past and it was a square tire setup.

However, the front size that I have is: 235/45/18, not 225. My mistake.

Also, I have found that difference manufacturers can have a .1" variance from each other in actual diameter even with the same size tires.

Yup.
You wrote 2 different things. On top you wrote 225/45-18. In the calculation you wrote 235/45-18. And I don't see 235/45-18 in the X-ice on Tire Rack, so I figured the right one was the 225...

Understood. I have since corrected that and noted "Typo" for it. I meant that I now have F235/45/18 and R245/45/18.

As for TireRack, I was under the impression that if it wasn't listed on TireRack it didn't exist. When I went to the manufacturer websites (ie. Michelin), you'll find that the tire was, in fact, made in 235/45/18.

Had I know this, I would have checked on Dunlop's website and perhaps have opted for the WinterSport 3D which seems to have been made for the original OEM size of 225/45/18 and 255/40/18, but it's not listed on TireRack.

Now, back to the the variance in circumference for my winter setup... I don't think the variance is enough to make the car go into limp mode or it should have done it shortly after the tire mounting.

I don't think so, because like you, I do most of mine in comfort mode as well. I'd be surprised if it turns out not to be the aux cooling fan.

Dealer said they could not find the "cause" of why I brought in the car but they read faults for:

1. Fuel rail pressure sensor
2. Transmission oil pan is leaking fluid but not enough to trip a low fluid level light (not a fault code - just observation)

They are replacing both parts, but it's unknown whether those will be a remedy.

However, the fuel rail pressure sensor definitely seems suspect.

Yeah, that definitely would be suspect. Better for it to be the sensor than actual fuel pressure issues, though.

These cars need sensors to sense the senors that are sensing Is any of this masking sense?
