I have an Audi A6 Avant (1995 N reg). There is an intermittent fault where
the oil light comes on and the rev counter stops working. Sometimes all the
warning lights come on with the rev counter still not functioning. After a
period of time, which can vary, the warning lights will clear and the rev
counter will start working again...
Already changed the oil pressure switch and tried new clocks, but fault
Anybody any ideas what this might be?
