I'm having the same problem. Any help?
I'm having the same issue. I bought my 335i wrecked but repaired everything mechanical and electrical. new starter. new bst. new key fob. new and great battery. checked all fuses. checked all relays. I'm having codes.
Engine/Motor
Generator, communication: Bus error. code: 2E98,
Immobilizer System:
Cas
Driver KL50L kS
Code: A0C1
Engine starter faulty operation
Code: A0B4
The car ONLY turns over and starts when its being boosted from the front engine bay terminals. When I checked the voltage on the battery while it was running it decreased to 11 volts when in reality it's suppose to increase between 13-14. The car will not stay running however, it eventually dies a few minutes later. Any suggestions?
