I had a yellow oil can symbol on the dashboard accompanied by the words "Oil sensor: Workshop!" so I fitted a new oil level sensor (not a genuine Skoda part) but the light still comes on. I went back to the motor factors where I bought the replacement part and they cross referenced the part number from the original part with the one that they supplied and confirmed that it is correct. (The wiring seems ok and the bonnet catch switch seems ok too because the dashboard display shows when it is open and goes off when it is closed, sometimes the catch switch can cause the oil light warning as well.

Do I need to do some kind of fault code reset to clear the fault?

So far I have used a code reader which showed no stored faults but it isn't a very expensive one, and I have also tried leaving the battery disconnected for a while. The original part number is 03C 907 660M and the engine code is CBZA
Thanks for your help.

Do you have access to a multimeter?

The part was dropped for a replacement, doesn't mean that the old part number won't work.

As you have replaced it, odds are it could be a wiring fault, hence @Breezy_Pete advice about a multimeter.

 

Check cabin fuse 3 is intact first, it should be a 7.5A rated one; then with ignition on, measure between pins 1 (black/yellow wire) and 2 (brown wire) of the sensor connector hoping to see 12V.

That, if seen, confirms that 2 of the 3 wires are intact. The third one from pin 3 ends up at the instrument cluster, pin 11 of the 32-way connector there.

Thanks for the advice, I do have a multimeter so I will check the readings and get back to you

The wiring appears to be alright so I’ve replaced the oil sensor again, this time I have used a genuine Hella part. I noticed that when the other new part was fitted the oil temperature reading was quite erratic, randomly going from nothing to very high, this has settled down now and sensible readings are now showing up.

The oil level light didn’t appear again for a while after the Hella part was fitted but it’s now making occasional appearances. Does anyone know the point at which the light is triggered? I always keep the oil level near the maximum point of the dipstick.
