Thank you for making this guide. I've just done this to my car and it's made a massive difference to the sound of the engine. It's much more quieter and smoother running. I bought a FSi 2.0 timing tool kit from eBay for about £30 and that wasn't worth the money. I ended up going to VW and buying the correct cam holding tool, the correct socket for the exhaust cam bolt, and the lever for the intake cam. These are listed in your initial post, so look there for the part numbers.
Very easy job. I never removed the two PCV pipes at the back of the rocker cover (near the turbo). They were being a pain so I proped up the cover with a piece of wood. That gives you more than enough room to set the cam timing tool in position and do the timing chain/tensioner etc. So don't go breaking those pipes.
The gasket for the rocker cover was very brittle. I covered the open cams and removed the old gasket with a screwdriver, CAREFULLY! Don't break the plastic valve cover.
I searched around for timing belt kits etc and found that the genuine VW parts from the dealership was the cheapest.
After completing this fix and testing to make sure it works, I've followed it up with some CRC intake valve cleaner, oil and plug change and the car runs like a beaut. Doesn't sound like a diesel tank anymore
