Alright here is the problem, I have a 1994 E36 325is right. The other day I take it to a carwash and when it comes out it won't start. I tried everything jumping it, bump start nothing. So I have it towed to the BMW dealership and they tell me that it is my EMU computer, that it is all corroded and that I need a new one. I know the EMU is a computer but what exactly is it? If anyone knows if this has happened before, or if you know of a solution, or you know what is going on PLEASE HELP. I can' stand being away from my car.
