Hey all my car was good and driving and today driving on the freeway every warning light turned on I lost power steering and received drivetrain malfunction abs parking brake light and the car has about 20 codes and have no idea where to start. I seen an older post about the comfort access door handles fuse being faulty and have had issues with my door handle before but have no idea what fuse it could be. would appreciate any help as I have only had 335i before car runs amazing just popped up outta nowhere

Is the battery ok - a duff battery can cause all sorts of messages.

Battery could be the issue as it can cause all kinds of funky behavior. However, on G series vehicles, it is very unlikely to get this kind of behavior without BatteryGuard first catching the problem.
I haven't heard of door handle electronics causing this sort of behavior, but I can see how these could potentially cause vehicle to be kicked out of ready state. Comfort access door handle modules are fed by 5 amp fuse F13 that is located on BDC (body domain controller). If you have a list of diagnostics codes (not the ones that pop up on CID), then these could help further investigation. |

If car is already in ready state and driving, then key shouldn't matter. It might complaint about it not being detected inside the vehicle, but that should be it. My question is why are your keys not detected at times? I'm starting to see a theme here with BDC.
Aux battery is market and equipment specific, but seeing as your market is US and car is 750, then I'll go ahead and say yes, you have aux in front. |
