[s-cars] Question about IC

[Brian Powell]

Gents,

The wife's 96 A4q 2.8L decided today that the tach and speedometer
will no longer work. The tach just bounces off of zero constantly
(with engine off and key in ignition) and speedometer doesn't budge. I
tested with VAG-COM and I get an rpm and speed reading in the
measuring blocks, so presumably the engine speed sensor is fine.

Anyone know how to diagnose/repair an instrument cluster? If I have to
pick up a used one, does anyone have the VAG-COM procedure for
recoding the used cluster to the right mileage, etc.?

Thanks!
