Note

To functionally check and service the optical and acoustical oil pressure display system,

Wiring diagrams.

- Remove the 1.8 bar oil pressure switch (white) and thread it into tester VAG 1342

- Thread the tester into the oil filter flange in place of the removed switch

- Connect the brown wire of the tester to ground

- Connect LED tester VAG 1527 between battery positive and-A-the 0.3 bar oil pressure switch (F 22) using jumper wires from the VW 1594 adaptor kit the LED tester must light up

- Start the engine and slowly increase engine speed between 0.15. to 0.45 bar the LED tester must switch off, if not, then replace the 0.3 bar pressure switch

Oil pressure and oil pressure switch, checking (Page 17-9)

- Connect LED tester to -B- 1.8 bar oil pressure switch (F 1) between1.6 to 2.0 bar the LED tester must light up, if not, then replace the 1.8 bar oil pressure switch

- Increase engine rpm at an engine speed of 2000 rpm and an oil temperature of 80 C (176 F) the oil pressure must be 2.0 bar minimum
