    I struggled with the belt change on my girlfriends old A3 2.0TDI last year, the pulley came off the alternator and i managed to swap that over no probs but then was messing around for ages with the tensioner. I was trying to undo the big nut on the side of it and all sorts with no luck.

    Its spring loaded and once I'd spoken to a mechanic mate of mine it was really simple. As you look at the tensioner and belt there will be a flat section of the tensioner with which you place an open ended spanner on and push down releasing the tension of the belt. As usual I can't remember exactly what sized spanner it was but it will have been at least a 13mm possibly a 17mm.

    I know the engine is the other way in the A4 but if anything it should be a simpler job to swap the belt than on the A3 once youve figured out which way the tensioner needs to rotate.

    If you do a search for changing the serpentine belt it may bring up a diagram, I also asked on the ukmiv's golf forum and I'm sure someone posted the picture but as I said above I'd already sussed it after talking to a friend.
