Hi I have a my 03 passat tdi with on oil warning message,I have checked the wiring down to the sensor and have the following readings
Pin1 Battery voltage
Pin2 Ground
Pin3 10v?
I thought all of these readings where ok so assumed the fault was with the level sensor,I replaced this component and no change?Is there any known wiring issues with this fault or is it a control issue?If anyone has a wiring diagram and the necessary information it would be gratefully appreciated.Thank You
