How to Repair the Oil Pump Failure on a 2006 Audi A4

Model: Audi A4 B7 - Years 2004-2008
Part: Pump

This model's engine, particularly those equipped with the 2.0 TDI, can experience lubrication issues due to a failure of the oil pump, which can no longer build pressure and circulate oil within the engine block. The failure is often caused by wear on the internal shaft seat connecting the balance shaft and the primary shaft of the pump. This connection is made through a hexagonal shaft that also wears down, but the internal seat of the pump shaft tends to become nearly circular, preventing it from being driven properly. A specialized workshop can create a key seat or rebuild the hexagonal seat to extend its engagement.
