Vwwbeetle Posted July 27 Report Share Posted July 27 Hi, I own a 2005 Lupo with the 1.0 AUC engine with power steering. The auxiliary belt has a whine because I have taken the belt off and it has stopped so I’m wondering what it could be. I’ve already changed the tensioner, PAS pump, alternator and the belt so I’m wondering if anyone else has had the same issue and managed to fix it. thanks Quote Link to comment Share on other sites More sharing options...
mk2 Posted July 27 Report Share Posted July 27 Sounds like one of the pulleys might be running off line- the belt might be trying to go round a corner? Put a steel straight edge on each pulley face, comparing with a neighbour till you find it... Quote Link to comment Share on other sites More sharing options...

I’ll try that when I get home and I’ll report back Quote Link to comment Share on other sites More sharing options...
Vwwbeetle Posted July 28 Author Report Share Posted July 28 quick update, i had a look to see if it was all aligned last night and it seems to be ok. Any more suggestions? Quote Link to comment Share on other sites More sharing options...
mk2 Posted July 28 Report Share Posted July 28 Air in power steering system? If all the bolt on bits are brand new, it can't be that. Maybe oil on the belt? Quote Link to comment Share on other sites More sharing options...
