squeal/whirl noise from mk4 golf on idle

[adaly86]

Hey, I have a 99 Golf Mk4 1.6 and today it went to the garage to get its shocks done, they also changed the gearbox oil which they said was very black and the reset the throttle body, when i collected the car this evening i noticed a slight whirl/squeal noise, and when i got home it was a bit louder, its only really noticable when idleing though, it kind of sounds like a belt or something, what could it be? They also adjusted the clutch pedals etc.

Have you checked the tightness of the belts on the powersteering and altenator?

no havnt done that, it seems to be when the car is heating up and then its fine when fully heated up, but ive noticed when the car is fully heated up the car seems to chuck along when accelerating in 2nd or 3rd between 1400-2500 revs, different problem?
