2010 A6 3.0T squeaking belt

[rayyan171]

Not sure if its either the supercharger/drive belt or a duff tensioner. It gets louder when revving the engine, but no loss of power or anything. Anyone have any idea? Video attached.

Any help would be appreciated.

Hi Rayyan,

Tbh i cant really hear anything due to background noise. if you suspect its the drivebelt then spray water onto the belt and see if the noise disappears. Do not use wd40 or anything equivalent on the belt It ll just cause the belt to slip and the alternator wont charge the battery correctly. If the water trick doesnt work then most likely the belt is fine. Next step will be to get a long screwdriver up to your ear and place it on the side of the suspected parts, this will show whether there is any shot bearings. Just be careful of any lose clothing etc.
