I'm confused on this one. I tried another rear turn light assembly and it did the same which tells me it's not the assembly.
I then disconnected the wire from the footwell module for few minutes, plugged it in and the turn signal worked for a week or so until this morning. It's only the right rear and blinks fast. Do I have messed up footwell module? I was also reading if you get a new one it will have to be programmed by bmw, is this true?
