Well, it's now been confirmed that my 2.0 TDI needs a flywheel, starter motor and the head gasket is also gone. Whoop de doo!!
Since owning the car from August 2012 the car has had a new inlet manifold flap, 4 spark plugs, a new turbo and a new radiator, now a flywheel, which seems to of taken starter motor too as it does struggle to start and I am losing coolant so suspect head gasket.
Think I'll be selling the car once it's running healthy again.
