My Ride: 2003 M3 convertible
Major problems :-(

So I have a 2003 M3 convertible.... SMG transmission. The SMG transmission light is on and my car would randomly go into neutral and then not shift. I'm afraid to even drive my car now and that it will go into neutral in the middle of the highway. I did the salmon relay thing.. The light went away for like 10 miles and then came back on and I had to struggle to get my car back home with out being stranded in the middle of the road and looking like an idiot. Also, before the light came on, my car would be in automatic mode and not shift. I'd have to apply the brakes gently, wait a couple seconds and then my car would wake up and shift. That usually happened when I had to make multiple stops in little time. What could be wrong?? Like I said I did the salmon relay thing... VERY temporary fix. I live in the desert in southern California if that means anything.

I'm sure this has been addressed somewhere but I think everyone's solution is the salmon relay thing.

Replacing the salmon relay, is just a quick first step to rule that out. It will only fix one of many possible problems you may have. No one is going offer up too much advice until you go have someone pull the SMG specific codes with some type of specific BMW scanning software.
