[Vwdiesel] timing belt and adjusting timing

[mark shepherd]

Forget the tensioner, unless the bearing has gone. [If it spins freely and 
with no sideways rocking, then it is fine]
Your problem is likely an overtensioned belt  making the pump's bearing 
behind the pump pulley oval, or indeed a loose pump mounting. or loose pump.
