Inspection
Completely disassemble the oil pump and thoroughly clean all of the components. Inspect the oil pump gears and housing for wear and/or damage. Insure that the pressure relief valve operates properly and there is no binding or sticking due to varnish or debris. If all of the parts are in proper working condition, lubricate the gears and relief valve, and assemble the pump.

During the production of the 1998 A4 models, beginning with VIN No. (last 6 digits) 005001, the 2.8L V6 engine oil pump has been relocated from the front cover to the oil sump, is chain driven and mounted to the front lower portion of the engine block.
The A4 models produced with the chain driven oil pump can also be identified by the appearance of the lower oil pan surface, which is smooth unlike the finned oil pans found on earlier models.
To replace the oil pump, proceed as follows:
- Note the radio security code and disconnect the negative battery cable.
- Raise and safely support the vehicle.
- Drain the engine oil into a suitable container.
- Remove the engine oil pan.
- Remove the oil supply tube mounting bracket fasteners, and then remove the lager of the two supply tubes.
- Use a Torx® T45 wrench to remove the center bolt for the oil pump dive sprocket, and remove the sprocket.
- Remove the oil pump mounting bolts and remove the pump along with the short oil supply tube.
