Belt noise slipping?

[[QW-11-KE]]

hey guys i got a ve r8 purchased recently and had the fan belt replaced due to noise before i picked it up.... now i noticed the noise is coming back slowly slowly especially wen i start the car in the mornings

now its an auto and a few times ive also noticed when i give it a hit at high revs when the gears change n the next one kicks in it sounded like the fan belt slipped... sounded like a referee blowing a whistle for like 1 second.....

is the belt loose? or something else?

only no that when u start ur car for a few seconds sounds like the belt is noisy but its normal they all do it but mine doesnt do it when it changes gears

mine had a bit of a squeal on cold mornings.. took it back.. fixed under warranty.. apparently one of the pulleys needed to be adjusted a mm or so.. no more squealing

had this fix done 5 times now - still not right, but better - I've had belts changed, pulleys adjusted and replaced.

What pulley was it that you had replaced?

 

[TinSnips]

power steering pulley was replaced - twice actually - the replacement pulley was faulty too - go figure!

I can't remember what all was re-aligned - was a couple

edit: I should clarify - that was found to NOT be the cause of the noise - as it still did it afterwards! But it was an issue in itself.
