Engine Lubrication: Service and Repair
Lubrication system components, removing and installing
Note:
^ Metal shavings or large amounts of small metal particles found in the engine oil during repairs may be caused by a partial seizure of the crankshaft or connecting rod bearings. Perform the following work sequences in this situation to prevent consequential damage once repairs are complete:
- Thoroughly clean oil passages
- Replace oil spray jets
- Replace oil cooler
- Replace oil filter
^ The oil level must not be above the max. mark or there is a danger of damage to catalytic converter.
Disassembling and assembling oil filter bracket; Refer to Oil Filter, Service and Repair.
Engine codes BDC, BGD
Disassembling and assembling oil pump with balancer shaft gear assembly; Refer to Oil Pump, Service and Repair
Removing and installing oil pump with balancer shaft gear assembly; Refer to Oil Pump, Service and Repair
Continuation for all models
Checking oil pressure and oil pressure switch; Refer to Oil Pressure, Testing and Inspection
Engine oil specifications
Use engine oils which conform with VW standard 500 00, 501 01 or 502 00. Only in exceptional cases: Multi-grade and single grade oils conforming with API-SF and SO or ACEA A2lA3.
Note:
^ In the factory the engine is filled with engine oil conforming with VW standard 503 00. This engine oil is designed for long service intervals (ESI).
^ Engine oils conforming to VW standard 500 00, 501 01 or 502 00 may also be used.
