Kicker Posted April 17, 2019 Share Posted April 17, 2019 I have a 2011 Q5, recent drive belt went and due to redundancy could not afford a genuine audi water pump. Garage fitted alternative, car runs great as normal but there is a high pitch wine which rises and falls with the Rev of the engine. Can anyone help with this please.

Trevor Posted June 3, 2019 Share Posted June 3, 2019 Sounds like a belt is overtightened and straining the alternator bearings (or other anciliary component) Quote Link to comment Share on other sites More sharing options...
