I posted a while back about this, and here we go again... I have a '92 525i and just had some work done and the stereo is out and reading CODE again.
I still have the code written down from the last time (battery change), but now it won't work. Occasionally I'll get a short beep as I press one of the number buttons, but it won't activate. Is there some trick to it that I'm missing (or some step I'm not remembering)?
Any advice would be greatly appreciated.
