[A4] Fuel Tank-Pump-Gauge Issues?

[Nicholas Stock]

Phil, I believe the buzzing you hear on ignition is the fuel pump priming,
but I could be wrong. I had a few issues with a 'dodgy' fuel gauge on my
2000A4...turned out it was a faulty resistor on the sender unit....the Audi
technician stated that it was a pretty common fault, so you may want to
check that out...

HTH,

Nick
