Test sequence
–  Remove oil pressure switch -F1- in the front left of the cylinder head.
   
–  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 and to oil pressure switch.
If the LED lights up:
–  Replace oil pressure switch -F1-.
If the LED does not light up:
–  Start engine and slowly increase engine speed.
   Given an oil pressure of 0.03...0.07 MPa (0.3...0.7 bar) the LED must light up, otherwise replace the oil pressure switch.
–  Increase engine speed further.
   At an engine speed of 2000 rpm and an oil temperature of 80 °C the oil pressure should be at least 0.2 MPa (2 bar).
At a higher engine speed the oil pressure must not be greater than 0.7 MPa (7 bar).
