📋 Procedure
- Remove oil pressure switch F1 and screw it into tester.
- Screw tester into oil filter bracket in place of oil pressure switch.
- Connect test instrument/DSO adapter (2-pin)VAS 5256 to oil pressure switch
- Connect MultimeterV.A.G 1526D to test instrument/DSO adapter (2-pin)VAS 5256 and check for continuity.
- If oil pressure switch is closed, renew oil pressure switch.
- Start engine and increase engine speed. At 1.2…1.6.bar, the oil pressure switch must close, otherwise renew oil pressure switch.
- Increase engine speed further.
- Check strainer in oil suction pipe for contamination/soiling . [Note: Mechanical damage, e.g. to bearings, could also be the cause for oil pressure being too low.]
- Renew balancer shaft gear assembly with oil pump .
- Check oil channels.
- If necessary, renew oil filter bracket with pressure relief valve.

Who makes these pages, and how
TorqFix was built by a mechanic — after a 2,700 km drive with five roadside repairs that no diagnostic tool could explain.
The figures on this page come from manufacturer workshop documentation and are shown as they are. The page is assembled automatically from that data — it is not written by an AI. The AI works in the chat, where it answers for your specific car. It writes nothing here.
Variants of the same model differ. Cross-check torque against the factory manual for your engine before final tightening.
