I just purchsed a 1994 Audi 100S with 114,000 miles

When I accelerate from a start or when I am at Highway speeds the Oil
Pressure warning light flashes with the 3 beep warining sound.

However, the pressure gauge is always reading somewhere between 2 and 4
bars. In fact it seems that the light mostly comes on when the gauge is
reading higher.

Any thoughts?

 

I don't know if this will help but we had a similar problem with our
1989 Audi 100 and we had to have the oil sending unit replaced. It was
working fine and there was always the right pressure but it was sending
a false code and the warning light and beeper were coming on.
