S3 whine after having cambelt and waterpump replaced.
about a month ago my original waterpump packed in and since I bought it from a garage a couple of weeks prior they fixed it at no charge to myself (and did the cambelt too).
I noticed that I have a high pitched whining noise that's quite audible from outside the car (less so inside) but thought I'd give it a couple of weeks to clear before going back to the garage.
I still have it, it sounds like a supercharger kinda noise so if you idle and blip the throttle you can hear it rising and falling with the revs. I initially thought it was the secondary air pump but after a long drive (120 miles) you could still hear it at the destination.
I'm thinking that the bearings in the waterpump are faulty or could it be something else? I'm going to take it back to the garage but I like to go armed with some information beforehand to save them ripping the thing to bits and me having to take the bus everywhere...
