Volkswagen Golf Service & Repair Manual: Checking oil pressure

Special tools and workshop equipment required
   
Oil pressure tester -V.A.G 1342-
Procedure
Oil level OK: checking → Booklet.
Engine oil temperature at least 80 °C (radiator fan must have run once).
–  Remove oil pressure switch for reduced oil pressure -F378- → Chapter.
–  Screw oil pressure tester -V.A.G 1342- into hole for oil pressure switch.
–  Screw oil pressure switch for reduced oil pressure -F378- into hole in oil pressure tester -V.A.G 1342- to seal it.
–  Start engine.
Check oil pressure at idling and at 2000 rpm
Oil pressure at idling speed: at least 0.6 bar.
Minimum oil pressure at 2,000 rpm: 1.5 bar.
–  Switch off engine.
Check oil pressure at 3,800 rpm
–  Remove electrical connection from oil pressure control valve -N428- → Anchor.
–  Start engine.
–  Increase engine revs to 3800 rpm and read off oil pressure on the oil pressure tester -V.A.G 1342-.
Minimum oil pressure at 3800 rpm: 2.8 bar.
If specification is not attained:
–  Connect electrical connection to oil pressure control valve -N428- → Anchor.
–  Interrogate the engine control unit event memory and delete all event entries → Vehicle diagnostic tester.
–  Check valve for oil pressure control -N428- with → vehicle diagnostic tester.
  Note
Mechanical damage, e.g. to bearings, could also be the cause for oil pressure being too low.
If no fault is found:
–  Renew oil pump → Chapter.
Check oil pressure switch for reduced oil pressure -F378- (brown):
–  Switch off ignition.
 

Checking oil pressure

–  Connect brown wire of tester to earth (-).
–  Connect voltage tester -V.A.G 1527B- to battery positive (+) and oil pressure switch for reduced oil pressure -F378- (brown) using cables from auxiliary test set -V.A.G 1594C-.
LED must not light up.
–  If LED lights up, renew oil pressure switch for reduced oil pressure -F378-.
If LED does not light up:
–  Start engine: At 0.3…0.6 bar the LED must light up, otherwise renew oil pressure switch.
Check oil pressure switch -F1- (blue):
–  Stop engine.
–  Connect voltage tester -V.A.G 1527B- to battery positive (+) and oil pressure switch -F1- (blue) using cables from auxiliary test set -V.A.G 1594C-.
LED must not light up.
–  If LED lights up, renew oil pressure switch oil pressure switch -F1-.
If LED does not light up:
–  Remove electrical connection from oil pressure control valve -N428- → Anchor.
–  Start engine and increase rpm: At pressure of 2.15…2.95 bar LED must light up, otherwise renew oil pressure switch.
–  Connect electrical connection to oil pressure control valve -N428- → Anchor.
–  Install oil pressure switch for reduced oil pressure -F378- → Chapter.
–  Interrogate the engine control unit event memory and delete all event entries → Vehicle diagnostic tester.
Specified torques
