Audi 100Q electrical demons

[Judy Kaiser <ssvolvo@mt-mansfield.com>]

Hi John (writing from my shop's account)...
My technician asked me to poll the list for hints on a recurring problem
they have seen on several 100's (10vq).  In four separate instances, the
directional indicators work opposite of their intended function (i.e.,
not in sync with the outside blinker).  In addition, the hi-beam
indicator operates only when the lo-beams are on, not when the hi-beams
are on.  Obviously, there is a ground connection fault somewhere on the
instrument cluster circuit board.

Has anyone effectively diagnosed a fault with the printed circuit board
on the back of the instrument cluster without replacing the entire
cluster?  Anyone?  Bueller?

For those of you on the mother list, please reply directly (not
subbed).  Thanks.


Thanks,

Ray Tomlinson
