Hi guys, i think my alternator clutch has gone as the belt is jumping everywhere on tickover, making hell of a noise when turning wheel at low revs.

just need to know the part number so i can order one in the morning.

Car is an A4 1.9tdi avant sport with A/C. Not sure if 5/6pk as its difficult to see.

Anybody know the part number based on that info?

Thanks in advance,

Jamie.......
