Hi all,
The speedometer and rear spoiler on my 91MY 964 C4 suddenly stopped working today. (The rear spoiler light says on.)
My guess is that the Frequency Modulator control unit on the relay board may need replacing. Not cheap.
Or could it be one of the speed sensors? Also, not cheap!
Any pointers appreciated...
