Unable to check oil level - sensor codes read

Hi

Been trying to check the oil level using the instrument pod service menu but consistently reads 'not available' despite waiting 20, 30, 60 mins or overnight for oil to settle.

Check for fault codes and following appear:-

P250D-37 - oil sensor circuit high
P250B-87 - oil sensor circuit range/performance

The codes are permanent - reappear immediately after clearing

At this stage I admit to being a numpty but do these codes indicate that the oil sensor needs changing or is it a wiring loom issue. If the latter where do I find the wiring connector/loom for the oil sensor on the sump??

Checked on here and realise it's a front diff and sump off to replace the sensor. Hopefully WD cover if required.

Thanks

PS - D4 now in 4th year, 32K miles and aftermarket warranty

PPS - what was wrong with a manual dipstick!!!!!!!!!!!!!!!

PPS - should have mentioned - no warning lights yet so assuming oil levels OK after service at 29K miles Club RLD spare wheel protection

The only warning you will get will be no oil pressure warning. If this comes on, it’s too late, as it will have run out of oil!

I’d suggest fixing as soon as you can.
Regards

Thanks Steve

Already on the case with my friendly indie. Oil level is OK, checked using the 'curtain wire' method. Now just waiting for Scotland to ease lockdown or to become a Senior Advisor to someone in UK Gov!!! Club RLD spare wheel protection

Its a massive job to remove the sump on a 3.0

The wiring loom fills with oil (just like Td5 injetor loom) which short circuits inside the electrical connector, giving the "Oil Level Unavailable" message My D3 Build Thread

I had a situation when the oil level could not be displayed, but I am not sure if there were any error codes logged. Took it to a garage and they found that the oil sensor cable was not fully connected - they cleaned it up and reinserted which solved the problem.
Try to check all connectors in the first place - it should be relatively easy.
