I'll do that if someone with some photo editing capability will take my raw pix and by working with me add some notes on the pics as to what we are looking at. You got it!

BTW, to ALL. FORGET the repair kit BMW mentions. I don't know if there even is such a thing anymore, but at the price you can just forget it. Also, these steering (yaw) sensors do feed the DSC/ABS module. They just don't seem to fail all that often so I have chosen to ignore them. They certainly can be a DSC/ABS/Brakes error cause, but they are expensive and only fail ever so often. If all speed sensors check ok, and the module has been re-built or appears ok and you still face an elusive error, then check with carsoft software or BMW GT-1 to verify
