Hi guys, thanks in advance!

I've just bought a 2002 1.8SE A3 it's covered 82k and has full Audi service history.

With the air conditioning switched on you get a knocking noise, with it off the noise goes away. The ac is working really well.

Is it likely to be the ac pump? or the belt/tensioner? has anyone had it before?

Thanks again
