Workshop procedure for VW — the exact step sequence and torque figures, straight from real workshop data.
🧭 Before you start
Fits: VW Sharan II / SEAT Alhambra (7N, 2010–), VW Golf Cabriolet (517, 2011–2016), VW Passat B7 saloon (362, 2010–2014), VW Passat B7 Variant (365, 2010–2014), VW CC (358, 2012–2017)
- Renewed: oil pressure switch, oil pump
Don't miss
- Connect voltage testerV.A.G 1527B to battery positive (+) and oil pressure switch using cables from auxiliary measuring setV.A.G 1594C. LED must not light up.
- Start engine and increase engine speed. At 1.2…1.6 bar, the LED must light up, otherwise renew oil pressure switch.
- Mechanical damage, e.g. to bearings, could also be the cause for oil pressure being too low.
📋 Procedure
- Remove oil pressure switch F1 and screw into tester.
- Screw tester into oil filter bracket in place of oil pressure switch.
- Connect brown wire of tester to earth (-).
- Connect voltage testerV.A.G 1527B to battery positive (+) and oil pressure switch using cables from auxiliary measuring setV.A.G 1594C. LED must not light up.
- If the LED lights up, renew 1.4 bar oil pressure switch F1.
- Start engine and increase engine speed. At 1.2…1.6 bar, the LED must light up, 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 oil pump .
- Check oil channels.

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.
