l  Engine oil level o.k., test:
t  → BookletFabia II.
t  → BookletRoomster.
t  → BookletOctavia II.
t  → BookletYeti.
  Note
Functional test and repair of the visual and acoustic oil pressure display → Current flow diagrams, Electrical fault finding and Fitting locations, → Vehicle diagnostic tester.
Test sequence
   
–  Disconnect plug -1- and remove the oil pressure switch -2-.
  N17-10209
–  Screw oil pressure switch into the test equipment.
–  Screw tester in the cylinder head instead of the oil pressure switch.
–  Connect brown cable of tester to earth (-).
–  Connect voltage tester to battery positive terminal and to oil pressure switch.
l  The LED must not light up.
If the LED lights up:
–  Replace oil pressure switch -F1-.
If the LED does not light up:
–  Start engine and increase engine speed.
l  The LED must light up at an oil overpressure of 0.03…0.07 MPa (0.3...0.7 bar), if not replace oil pressure switch.
–  Increase engine speed further.
l  At 2000 rpm and an oil temperature of 80°C the oil overpressure should be at least 0.2 MPa (2.0 bar).
At a higher engine speed the oil overpressure must not be greater than 0.7 MPa (7 bar).
Tightening torque of the oil pressure switch: 20 Nm
