Hi all just joined this isnt really the first post i'd like to put on the forum but bought a 56 mk5 gti recently(46'000 miles FVWSH) and its started making a knocking noise on idle a diesel like idling sound i have had a few people look at it and they have said it could be the water pump ,another said fuel pump another said cam bearing or followers, im battered with it just to add it does'nt affect the way the engine/car pulls it drives fine pulls like a train with no hessitation or smoke any ideas?? just to add it has a 6 months warranty so im keen to get it sorted as i love the car
thanks.john
