Pressure and oil pressure switch: checking
Special tools and workshop equipment required
t  Oil pressure tester -V.A.G 1342-
t  Diode test lamp -V.A.G 1527B-
t  Auxiliary measurement kit -V.A.G 1594A- or -V.A.G 1594C-

Oil pressure switches: checking
  Note!
Checking the oil pressure switches is done by using the -V.A.G 1342- kit and the diode control lamp -V.A.G 1527 B-; the auxilliary cable set -V.A.G 1594 A- can also be used to make the connections.
   
–  Extract the 0.25 or 0.3 bar oil switch (blue of brown insulation) and screw it into the -V.A.G 1342- tester.
–  Fit the pressure inlet adaptor of the kit into the 0.25 or 0.3 bar switch housing.
–  Connect the brown cable of the kit to earth.
–  Connect the diode control lamp -V.A.G 1527 B- between the positive battery terminal and the terminal of pressure switch A of 0.25 or 0.3 bar in the kit.
–  The LED must light-up.
–  Start engine and slowly increase engine revolutions.
A pressure of:
t  0.25 bar switch: 0.15 … 0.35 bar of positve pressure.
t  0.3 bar switch: 0.15 … 0.45 bar of positve pressure.
The LED should go out.
–  If it does not do so, replace the 0.25 or 0.3 bar pressure switch.
–  Disconnect the diode lamp of 0.25 or 0.3 bar pressure switch A, and connect it to the 0.9 bar pressure switch B.
The diode lamp should light up between 0.75 and 1.05 bar.
–  If it does not do so, replace the 0.9 bar switch.
