So, my e46 M3 has a couple of electronic issues that recently developed. The drivers side door lock will lock via keyless, but will not unlock. The lock also does not function at all via the center console button. The other issue that happened simultaneously is the passenger side view mirror does not tilt...when put in reverse or when trying to adjust. It still moves side to side.

I have had a few people suggest that the general module is to blame, while others have said it is the door lock actuator and that they have no idea why the mirror won't tilt. I am pretty sure it was bmwgm5.com that I talked to about these issues and they are the ones that suggested actuator and had no input on the mirror.

What are your thoughts...? I obviously want to be able to address this for as little money as possible. Buy an actuator from bavarian recycling...then the gm5 if that does not correct the issue? Thanks all.
