I've been living with my conversion for a couple of years now and it's come the time to change the PAS belt. Unfortunately, the replacement belt seems to be too long and even at the max I can tighten it, it still has too much play. The VW belt was 10x648 and the replacement part (non VW) is...

I'm in the midst of dropping an ahu tdi unit from a mk3 golf into my early t4, and have been trying to figure out whether I can fit the air con from the golf in while I'm at it. It's only basic air con so not the climatronic system, so hopefully it shouldn't be too complicated. Has anyone done...

Its time to put all the TDi conversion threads in one place to help others as its a bit of a mission to find information through so many lost threads. Please can all 1.9tdi owners log all your threads relating to your conversion work so we have them all in one place. This seems like a good idea...
