Re: Strange Speedometer Behavior

Hi Bob,

There's an Audi service bulletin which describes an intermittently open
wire on one of the circuit boards that make up your instrument panel.
It has pretty good directions for removing the boards, re-soldering the
bad connection, and reassembling everything.  One way to check is to 
give the top of the dashboard a good whack next time the problem occurs.
If it goes away, it's probably the problem I've described.  I have the
manuals on microfiche; let me know if you'd like me to look up the
number of the service bulletin for this problem.

Good luck,
Mike Rottenborn
