The "Drivetrain Malfunction" Issue

Dlucke17 · 02-17-2024, 09:11 AM

Ok fam,

I've had this 2011 550i for a little over a month now and have been fighting this malfunction since. I've read thousands of posts (with thousands of different resolutions), I've done my own troubleshooting, I've taken it to BMW.... Could use another set of eyes....

ISSUE:

Like half of the threads I have read, the car starts every time and runs perfectly (I assume as new owner, but no mechanical issues) until the multitude of lights come on. There seems to be NO rhyme or reason. I thought at first that it could be a lack of fluid b/c it was usually happening when the car would get into 7th or 8th gear, but that is no longer the case. Sometimes at low speeds, could be cornering, a bump, I sneeze, hell, anything!

Usually, the car is still driveable only feeling a difference in steering stiffness and a slight lack in power. Sometimes the car falls into limp mode and I have to stop, kill the car, restart, and all is fine (until the next bump).

NOTES:

I bought the car knowing it was a rebuilt title and knew that the rear brakes and sensor needed to be changed, headlights were shot, needed a new battery, and the owner said one of the injectors may need to be replaced soon. I fixed all of those issues except for the injector b/c I have not seen any codes or driveability issues showing there is a problem. The car has, had, DCS, ICM and all of the no longer working suspension parts, which I have coded out (I think... Even unplugged the DCS module, pass footwell area).

TROUBLESHOOTING:

- I started with the rear brakes and that sensor
- I have replaced the right/rear sensor 3 times now and ALL sensors just to be safe. Right/rear seems to be the reoccurring DTC
- I have replaced the connector female clips that hold the ABS and brake sensors (both clips were broken)
- I have installed ECS coilovers (a whole another shit-storm of comments with that crap) and followed the DCS de-coding process
- I have tried to update ALL modules with latest software (BMW dealer also did this)
- I've cleaned the MAFs
- I've checked all plugs under the hood and installed the ARM intakes
- I've changed the oil and tranny fluid with new pan. Checked fluid like 6 times
- When I took the car to BMW for Diag, they cleared all codes and memory and the only thing that flashed back up was the right/rear ABS sensor. BUT, after clearing again and test driving they could NOT reproduce the code. FYI, the codes popped up for me once I got to the first light leaving the dealership.... UGH

UNRELATED (I think):

- I also have been fighting with a possible break in the fiber optics cable when installing Carplay, which is throwing the "No Message Tones" alert with intermittent sounds.
- I most likely have a heater core issue (slowly losing coolant but no visible leaks. No heater. Slight smell in the cockpit that I cannot id)
- I am 1000% sure I have jacked something up while coding with the below. NOT new to cars - VERY new to the coding side of things

I am hoping that the codes below offers some sort of light bulb for someone else who has seen these issues. I've read that it could be the ABS module, IVM (not even sure the 550 has one of those) issue, fluid issues, MAF issues, injectors, coils/plugs, sensors, WTTTTTHHHHHH???
