hi all i am looking for a bit of advice regarding the alternator belt tensioner pulley. my car is an a4 1.9 tdi b6 with the 130 bhp engine and the tensioner pulley is chirping what i need to know is is it possible to replace this without pulling the bumper forward into the service mode . any advice would be much appreciated .

I've done it on a 1.8 with out putting in service mode, very tight though...

The problem may be with your alternator pulley one way clutch, it is unlikely to be the tensioner, I have done two today.

hi thanks for the reply . i replaced the alternator clutch 2 weeks ago thinking that was the problem but unfortunately the chirp was still there . although there was some play in the clutch replacing this solved the vibration i was getting when turning the steering wheel when parking etc

OK, so the pulley damaged the tensioner, that does happen.

I can’t do it, I just can’t get my hands in there.

hi all ok i have bought the new tensioner , from what i can see there is only one way of fitting it. it as a threaded hole in the rear am i correct in thinking it just screws off
