Hi
Good luck with the repair and keep us all posted with pics if you can, I personally had a belt snap on my Passat B4 at 300k miles there was no damage whatsoever, I was told it was a non interference engine, not sure if the A2 is the same, although it is a scaled down 3 cylinder version of the 1896 VW tdi I believe but may be wrong with my info. I am sure you will get any help you may need right here.
