Hello. Im new here. Was looking for info about speedometers. I have a 00 audi a4 1.8tq and I want to update speedometer from S4 b5 99 with board computer (mine has no board computer - shows just outside temperature). I know that I need more then speedometer, but I am actually interested if its possible, that S4 speedometer will work corectly in my a4? If its compatible. Thanx

 

I don't have an exact answer. Hopefully this thread will help you:

Thank you.
