Only had my 6 around 3 months and really making some progress with it, but I've noticed 2 things which need addressing:
1. The Aux belt (which looks fairly new) runs 1 groove over to the N/S (right as you look at the engine) on the top Power Steering Pump pulley, I've tried realigning it and it squealed for a bit and then moved back to the same position... presumably it naturally wants to sit there but I don't know why.
The rest of the run is fine, everything lines up, and the P/S pump looks to be fitted correctly, all the way onto the mountings with no gaps.... my only thought was that it's either a non GTI6 pump (perhaps with a different offset) or the pulley is adjustable and needs to be moved in. Any ideas?
2. There is a slight whine from the engine, sounds like a belt tensioner and obviously could be related to the above, it get's quieter as the engine warms up, but still remains after everything is upto temp, you can only really hear it manoeuvring at lower speeds but the note does change with steering angle and revs so I guess it's the Aux belt system.
I need to remove the belt I guess and test all the rollers / pulleys and run the engine without it to see if the whine goes, but my main question is - would a worn roller cause the belt to move across, and how can I fix this, can the pulley be adjusted?
Cheers
