Just bought AUDI A4 03 PLATE 1.8T,6 SPEED,190 BHP which has developed this whirring noise which gets louder when speed is increased. The sound appears to be coming from below passenger side seat and when clutch is down and gearbox is dis-engaged the sound is still present.I've been told it could be the gearbox whine and not the wheel bearing which i suspected!!! So far i've done the service (oil/filters/plugs/coolant),had the cam/alternator belt changed,new tyres fitted.Yesterday i had gearbox oil checked and level was ok.What next???
I WOULD VERY MUCH APPRECIATE ANY ADVICE FROM FORUM COMMUNITY
