I have a 1998 Audi A4 TDI with the 110 BHP engine.
I know that diesels are noisy in comparision to petrol.
When I accelerate I can here a ticking noise above the usual diesel sound.
Ther is no loss of power or smoke or problems other than the noise itself.
It seems to be coming from the fuel pump.
is this a symptom of something worn or is there a known fix?
The MPG is fine.
I could discribe the noise as slightly tappety but i dont think it is the valve gear.
