Hi this is my first post. So basically sooner jerk tried to steal my 328xi and took my key and all my fuses out I finally got my key back and I thought they might have screwed with it so I opened it and it looks like they didn't do anything to the key but then I replaced the battery with just a regular 3volt similar battery but not rechargeable. Could that be the problem. I think I got all the fuses back . So starting it is first then I'll get into the tranny shifting All crazy it doesn't slip it just will skip second and downshift hard. But once it's on the hiway its fine.
The battery in the key fob is for the remote lock/unlock feature.
The first step in diagnosing a problem is to scan the car’s modules for codes. Find a reputable indie shop that specializes in bimmers at www.bimrs.org.
