Re: Speedometer "FIX"

[Roland Broberg <broberg@cpg.mcw.edu>]

I also have some experience with fixing both mechanical and electronic Audi 
speedos.  The worst trial was the electronic intermittent.  The fix, once I 
figured it out, was simple.  The cause was obvious.  When resetting trip 
odometer (mechanical push of button) the heavy handed person may give it a 
good shove. Crack!  The board that the button is mounted on is kind of flimsy 
and the pc traces are easily fractured.  Simple solder job and no more 
intermittent.  If you are scared of the job, consider the Audi solution, send 
the entire instrument cluster to california-no loaners thank you-and, as I 
recall the cost was several $100's.
