Hi guys Had a conversation with Dean at powermax this morning regarding replacing the balance shaft in the BLD 2.0tdi im looking at buying. Ive been weighing up is prevention better than cure, and the cost of the upgrade on top of the purchase price of the car needs to be considered Dean was very helpful full of good advice. He also mentioned as this model is the gear driven oil pump, to replace the balance shaft and hex is just a matter of dropping the sump and replacing the unit.. Is this correct?? Has anyone done this or had it done to their 2.0tdi????
