Is it possible to remove and change the hex drive shaft that runs the oilpump on the 2.0l TDi engines from below the engine via the sump.... from what i've seen they all seem to show you having to strip all the front of the car off and all the timing gear.... Dads bought a new Avant and I would like to check this common failing part for peice of mind but it looks like it's going to be a hell of a job... looking at it's service history it's had new cambelt and waterpump work done recently and something called a 91d4 quality enhancement which i'm going to start a sperate thread on
