Inspecting oil pressure and oil pressure switch (Superb II, Octavia II, Fabia II, Roomster)
Inspecting oil pressure and oil pressure switch (Superb II, Octavia II, Fabia II, Roomster)
Special tools and workshop equipment required
t  Oil pressure tester, e.g. -V.A.G 1342-
t  Voltage tester, e. g. -V.A.G 1527 B-
t  Measuring tool set -V.A.G 1594 C-
Test conditions
l  Oil level o.k.
l  Engine oil temperature approx. 80 C.
Test preparations
   
–  Lift the engine cover at the sides -arrows 1- and pull out towards the front -arrow 2-.
  S10-0209
–  Disconnect plug -arrow- at oil pressure switch -F1-.
–  Screw out oil pressure switch -F1 -.
  S17-0165
–  Screw the oil pressure tester (e.g. -V.A.G 1342-) into the hole for the oil pressure switch.
–  Screw oil pressure switch -2- into oil pressure tester (e.g. -V.A.G 1342 -).
Testing oil pressure switch
–  Connect brown cable -1- of oil pressure tester to earth (-).
–  Unclamp the voltage tester with its auxiliary cables out of the measuring tool set on the oil pressure switch and plus (+) terminal of the battery.
l  The LED should not light up.
If the LED lights up:
–  Replace oil pressure switch.
–  Start engine.
  Note
Observe the testing equipment and the LED while actuating the starter since the switching point of the oil pressure switch can already be exceeded when starting up.
l  The LED must light up at an overpressure of 0.055...0.085 MPa (0.55...0.85 bar).
If the LED does not light up:
–  Replace oil pressure switch.
Testing oil pressure
–  Start engine.
l  Oil pressure when engine idling: at least 0.08 MPa (0.8 bar).
l  Oil pressure at 2000 rpm: min. 0.2 MPa (2.0 bar).
If the specified values are not reached: Oil pump defective.
–  Replace oil pump.
l  Oil pressure at a higher engine speed: max. 0.7 MPa (7.0 bar).
If the specified value is exceeded: Pressure relief valve defective.
–  Replace oil filter holder.
