Oil temperature sensor
Ive recently had my D3 in for a air compressor swap since my last one finally gave in. Whilst the car was on the diagnostic I noticed an error for the oil temperature sensor.
Ive never had a warning light or any known issues with my gearbox. Is it normal for this fault to be listed and not give a warning light on the dashboard?
Not causing an issue just yet, so I will probably get it changed out then I get the timing belt done after xmas.

Can you clarify if you mean the engine oil temp sensor or the gearbox oil temp sensor?Land Rover - Turning Drivers into Mechanics Since 1948

Ok, sometimes resolved by unplugging and reconnecting the big electrical connector. If the sensor itself is at fault it is a bit of an event to get to it...
You will have no dash warning, but the shifts will be in default mode and the TC will be less efficient. You have no gearbox over-temp protection.

Thanks for the advice, much appreciated.
I'll try and hunt the connector out (unless you can state how to get to it).
Failing that ive been quoted £28 for the sensor and an hours labour for fitting it, i'll get this booked in with the timing belt after xmas if I don't have an issue.
Ive not encountered any noticeable effects with the sensor fault, it came as a surprise when I saw it on the diagnostic. Seems silly for a critical sensor not to have a dash warning light.

Connector is on the back right of the transmission so once the shield is off it is easy to get to.
My understanding was that the sensor was in the mechatronic unit, so the oil would have to be drained and refilled too - so I would expect a bill for up to 5L of ATF.
