has anyone heard of this. Every time i change gear my car makes a noise kinda like bill and ben. seems to be coming from the air intake to the turbo and after the turbo has n e one got a clue as to what it is?????
I think I know the noise you are talking about (bit before my time - lol).
Probably wastegate/compressor wheel chatter?!? If you've got an induction kit fitted it'll sound louder. Fiesta Turbos make this noise because the air filter is very close to the turbo intake.
if that is what it is how can i stop it coz it sounds toss...
