Just looking for insight, I have a 2016 BMW 328i that has been throwing drivetrain malfunction codes. I’ve taken the car to be serviced twice now at our Tom Bush service dealership. The first visit they conducted a full diagnostic, they re-coded my fuel pump module, replaced my valve cover gasket, and replace replaced a charcoal canister lining. They examined both fuel pumps (hpfp and lpfp) and they’re allegedly still in great shape. They also tested/examined the engine and saw no issues. Sent me back home and the car ran fine for 5 days and the drive train came back. Second visit they conducted another diagnostic and it was reported that the fuel pump module wasn’t receiving proper current due to the battery. Paid for a new battery. It’s been about a month since that last service visit and the car has thrown out the drive train malfunction message 3x now within the past 2 days.

I’ve noticed that this message usually only comes up when I’m at a stop light and about to accelerate. Sometimes the car allows me to continue driving after showing me the message and sometimes the car switches to neutral or park when it gets the code. I typically pull over and restart the car 1-2x and the message disappears and the car runs fine. Today I was at a stop light and about to accelerate when the car had a hard forward jerk/stutter before throwing the DTM message. After stuttering it felt as though the car was going to completely stop in the middle of the intersection but it suddenly jolted forward with slight pressure on the accelerator.

Not sure what else to get looked at. The car has been inspected by two shops and they’ve both said diagnostics look clean and they can’t pinpoint what could be causing the car to go into limp mode.

How you doing Sir. I recently had the same issue and it turned out to be something as simple as the "ABS Wheel Speed Sensor." I guess it throws a Short-Circuit and causes the Error Code for the Drive-Train to Pop up. I drive a 2019 430i Gran Coupe M-Sport and Ever since I had it replaced I haven't been having any Further Problems. I hope this helps!

I would Recommend any Sensors that regulates the Speed and Driving Dynamics for the Vehicle.

Yep. Ditto on the wheel speed sensor. Cheap and easy fix. I also had a bad/failing ignition coil that caused a bunch of lights on the dash.

Having a very similar issues. I’ve had my 2014 328i for about two years now. Had the chassis stabilization pop up, turned out my battery was bad so I got a new battery and then it went away. Couple months later, I got the chassis stabilization, drivetrain malfunction, and transmission overheating. The only codes on there are U1182 and U1187. Any help would be much appreciated
