    Electrical
    Hey guys, I was after some advice. I have a VW T4 from 1998. When I bought it the previous owner replaced the 1.9 engine with a 1.9tdi engine from a Seat Toledo. The wiring loom has so many spliced wires and they change colours and recently the van just wont run. It seems immobiliser...

I currently own my second 1.9 TD which I believe has 67bhp with 140nm of torque. Now, I do know there are...

  6. One for the TDi electrical experts.

    Engine & Gearbox
    I have finally got the conversion up & running to a point where I am very happy with the performance, but I'm still left with a couple of niggly little faults. The first is probably simple & just needs me to spend some time tracing wires & playing with the fluke, but the temp gauge doesn't work...

    Engine & Gearbox
    My T4 died the other day and I was hoping to put an engine in with a bit more grunt. Has anybody done a transplant for one of these beasts and what kind of options do I have in regards to engine size or type?
