Thank you for this thread! I am doing the same work on my 2000 1.8T. It is difficult to get my hands in all the small places to remove bolts, etc. But with your article I am encouraged!
A couple of things:
For the special tool for the tensioning pully, I used an M5x10cm stud cut down to 5cm. After threading the stud in, I used a nut and washer to take up the tension from the pulley. This was suggested by my Haynes manual.
Next, I was SURPRISED

with a face full of oil when I took the turbo to intercooler pipe off. About 250ml flowed out. There is probably a lot more in the intercooler.
Finally, how do I get the engine mount support bracket out? It is loose and free to move but there is not enough clearance to physically remove it!
