Strange issues with lost acceleration power on my BMW F10 535i (N55) xDrive mid-2014
Hello guys,
For around 2 months now I am a proud owner of a BMW F10 535i xDrive mid-2014 (LCI) N55 Engine. For the past 2 weeks, I have had strange issues with the car. Last week when I showed my car to friends, they asked me to drive them to show how the car drives, how fast it is, etc. (I guess normal stuff). Everything was okay, but when I switched to Sport Mode and drove them a little faster the check engine light showed up. I pull off and use BimmerLink to read the errors, which were: 4 errors 11B501: High fuel pressure after injection has been released: Pressure too low 11B401: High fuel pressure during or after the injection is released (2nd environmental condition sentence after time delay): Pressure too low 213901: Power management: active consumer reduction 1FB101: Power management: Battery falls below upper startability limit I cleared the errors using BimmerLink app on my phone, however, I noticed that the car wasn't accelerating as hard / fast as before. I feel like the car lost ~50 horsepower. 1 week after that no more errors were present, which is strange, as the car isn't accelerating as fast as before and I assumed that the errors would come again, but not. Today's morning I start my car and went to a friend of mine. Being there for some time and then start the car again and drove home, however, the second start was warm and immediately after I start the car I noticed a RED message on the Navigation screen saying something about DriveTrain issue, pull off and stop the car, something like that (I forgot to picture it). I started BimmerLink once again to read the errors and only these 2 errors were stored : 10 Central gateway module 1 error 801C20: Central fault memory full 12 Motor electronics 1 error 1B5102: Terminal 15_3, line from CAS, electrical: short circuit to ground After clearing the errors and starting the car again (worm) the same errors came up again. Does anyone have experience with those? On Monday I will go to the service shop to check my car, however, I would like to know if some of you have similar issues. The car has average mileage (if that matters) - 135 000 km (real, checked by the local BMW dealership). Sorry for my English. Last edited by eXRuLeZz; 09-17-2022 at 10:52 AM.. |

Today I’ve got another red warning on my bmw:
Drivetrain: OK Stop and turn off engine. Secure parking brake. Please call Roadside Assistance. And after checking the errors trough BimmerLink I can see only 1 error stored: Error code 1B5102 Error description Terminal 15_3, line from CAS, electrical: short circuit to ground And now my car cannot start. Maybe fuel pump? |

I think I solved the problem.
Talking with a few mechanics they suggest they should remove first the car's immobilizer (which was put in from my insurance company) in order to check what is wrong. From there I simply change the immobilizer's remote control battery and the issue is now solved! Pretty simple pretty strange… |
