ok

The belt can be retensioned and the pump timing adjusted just with the top cover off no need to strip the whole lot down.

Personally I dont remove the cam cover, I mark the cam sprocket and pin the pump, use the flywheel mark for the crank. The tensioner is very simple to set to the correct mark then I warm her up and check the timing dynamically. Job done.

sounds like a plan :) .
 
update

had a VW master tech work on it yesterday, and weve found the problem. i might post the photo's on here when ive got more time, but essentially once we pin'ed the cam and pump we couldnt see the crank timing mark on the flywheel. so he took the belt off and rotated the crank slightly, about a half to a full tooth, and it cam into view [:@] . so then we put the new belt on and warmed the engine up, and guess what the timming is now back where it was, albeit about 2 degrees different.
