Hey - on my 91 G60 Corrado, the needle on the speedo is reasonably wildly innacurate - it seems to 'stick' at certain speeds and always reads under by anything from 5 to 25mph.
If I maintain constant speed and reset the MFA showing averaged speed, the (averaged) speed reading seems to be very accurate.
I'm deducing from this that it is a problem with the actual mechanical head of the speedo unit - are these repairable or is it a replacement. Can the speedo part be replaced seperately or is it a full clock arrangement?
Thanks,
Chris.
