Affected pins

Instrument cluster connector B, pin 5

NOTE:
  • In total, 2 wires are connected to the sensor for the oil pressure indicator. The wire with the terminal designation "WC" (warning contact) is connected to the oil pressure switch which connects ground to the instrument cluster in the case of a stationary engine or low oil pressure and thereby actuates the warning light. A display warning is also emitted in the instrument cluster at the same time if the engine is running and the oil pressure is low.
  • The wire with the terminal designation "G" on the sensor for oil pressure indicator is monitored.
