Changed battery now have several DME Codes

bimmermw26 · 03-04-2026, 11:00 AM

I have a 2011 BMW 328i xdrive. The car was sitting idle for about a year and half and I recently changed the battery, received a new key, and now I have several codes and the engine won't go above 2 RPM.
The codes are:
002A77
002A3F
002E7A
002A87
002A7A
002DEC
002A77

Any assistance is appreciated.

Did you register the new battery to the car? Where did the new key come from? I don't know about those codes, I use the Carly for BMW app and module. I'd register the battery with the older key and go from there.
