Car: Audi A3, 2.0 TDI semi-auto, 70k,
Problem: About 2 months ago the engine managment light came on, i had a rough idle and the belt began to squeal, took it to Audi for diagnostics and they said i needed a new throttle body, tensioner and Aux belt @ £600+.... I bought the parts and fitted them myself, Audi had removed the fuse so once i figured that out the engine managment light went off, the belt stopped squealing but the idle was still rough..... the tensioner on the belt was bouncing and the squeal soon came back. We have run diagnostics on the car which came up with no faults.
Today the pulley on the alternator snapped off and the belt also came off.
If anyone has any ideas on what this could be it would be much appreciated. A video of the idle is shown below:
