My Audi 100 has a really annoying rattle which sounds like a small metal plate virating?? The car is very tidy and I've checked the brakes, suspension, bumper mountings, exhaust but everything is tight. My suspicion is the fuel tank, which had a new Bosch fuel pump fitted soon after I got the car (I can't remember if it vibrated before then as its not massively loud) - could it be rattling? I tried getting into it but even after depressurising the system the petrol just kept coming out - so I gave up. Could the pump be vibrating or the sender unit? How can I get into it without petrol going every where? Any advice greatfully recieved.
Also why does the fuel cap hiss every time I undo it - my last Audi did this too.
