Oil pressure and oil pressure switch: checking.
Oil pressure and oil pressure switch: checking.
Consult the equivalence table for tools and equipment according to applicability among Seat / VW / Audi / Skoda → Chapter.
   
Special tools and workshop equipment required
t  Oil pressure tester -VAG 1342-, see equivalent → Anchor
t  Voltage tester -VAG 1527B-, see equivalent → Anchor
t  Auxiliary cable kit -VAG 1594C-, see equivalent → Anchor

  Note
Checking operation of and servicing visual and acoustic oil pressure gauge → Current flow diagrams, Electrical fault finding and Fitting locations.
Test conditions:
l  Oil level: check → Fig.
l  Minimum temperature of engine oil 80 °C (the radiator fan must have started once).
Checking sequence
   
–  Remove the engine sound proofing cover, pulling upwards forcefully (-arrows A-) and remove forwards, from the rear attachment (-arrow B-).
Engine code BMT
  E15-0155
–  Detach the outer -1- and inner -2- engine covers, by pulling them evenly upwards.
All vehicles (continued)
  E01-10018
–  Disconnect electrical line -arrow- from the oil pressure switch -F1-.
–  Remove oil pressure switch -F1-.

–  Screw the oil pressure tester -VAG 1342- into the hole for oil pressure switch.
–  Screw the oil pressure switch -2- into the oil pressure tester -V.A.G 1342-.
–  Connect brown wire -1- of tester to earth (-).
–  Connect voltage tester -V.A.G 1527 B- with test leads from adapter set -VAG 1594 C- to oil pressure switch and battery positive (+).
The diode should not light.
–  If the LED lights up, replace oil pressure switch -F1-.
–  Start engine and slowly increase engine speed.
–  The LED should light up between 0.55 ...0.85 bar of overpressure; if not replace oil pressure switch -F1-.
–  Increase engine speed further. At 2000 rpm and an oil temperature of 80°C, the oil must have a min. pressure of 2.0 bar.
At a higher engine speed, the oil pressure should not rise above 7.0 bar; if so remove the oil pump → Chapter and check the discharge valve.
