Was @ a showroom yesterday to test drive a 2.0TFSi quattro. It hadn't been warmed up before being driven and upon lifting the bonnet I heard the a strange sound coming from the alternator side of the engine bay. I'm a complete newb when it comes to mechanics, so haven't a clue if it's something bad or something easily fixed like a belt change. Any help would be cool. It seemed to drive fine, but it was a short cruise as was at one of those car supermarkets. Sales man didn't have a clue either as to what it maybe, just wanted to assure me it could be sorted pre buying it. I'll try and attach the vid, dodgy quality but sound is good enough, this was when it was first started from cold. Excuse the camera moving all over the place I was trying to identify where the sound was coming from.
