Hi
I have the dreaded oil level not available fault (P250B-37). I have had the oil level sensor replaced with a new genuine one. The garage has applied power to the oil level sensor and it works fine. I have also had the service bulletin N375 applied but I am still getting the fault code. Anyone got a clue as to what to try next?

TIA

Could it be the sensor wires in the sump burnt out? I have oil in the sensor plug which I will get checked out very soon but my oil reading is fine, and apparently, the N375 modification has been done. overfinch modified

Hi
Thanks for the response. Unfortunately I think the wires in the sump are OK as when power is applied directly to the plug in the sump (so I have been told by my garage) it al works OK.

when I had the oil sensor replaced on my car I was first told by the garage that the problem was still not fixed. After authorising an additional 2 hrs of labour for diagnostics they came back to me and stated that a fuse had also blown, most likely as a result of the failed sensor, and after replacing it everything worked fine. Now, I know this wont be much help to you but I dont know which fuse they actually had to replace but I think the sensor is on the same connection as something else so it is not obvious but maybe a pointer of somewhere else to look?

It should be fuse F8 (15A/Blue) in the engine bay fuse box marked Engine Management System, (on post 2017 models its F24 - 15A)

Thanks guys, already checked that fuse. I fact I replied to ReggieMac's post on the LRUk Forums. If you follow the wiring diagram you can see the oil sensor on F8 event though it makes no mention of it in the manual. Am getting contact details for someone who only works on Range Rovers so will keep you posted.

You could try what the hack is to fix this on the L322...

I did this yesterday...

1. Open bonnet
2. Access service menu (ignition on, engine off)
3. Access where is says OIL LEVEL NOT AVAILABLE
4. Press the cruise control CANCEL button TWICE

This will then reset the indicator to whatever reading is for the oil within your engine.

But maybe this isn't the same for the 405?

Worth a try I guess.....

If the oil level sensor works with a voltage applied directly to it then finding the fault should be relatively simple - there will likely be a fault in the wiring between the engine bay fuse box and the sensor. With the aid of the wiring diagram and a test meter any competent auto-electrician should be able to find the fault. There is a connector C11 (I think near the fuel filter) that the 12v feed to the sensor goes through on a grey/yellow wire on pin 10, which is a good place to test to narrow down the fault location.
