Thread: Oil pressure warning light intermittent

The sender is under the turbo on the back of the engine. Do not be fooled that there are two wires. There is only one. LR must have got a discount on 2 wire looms but one is not connected to anything.

Like Philip said. Mine did this, and I found the wire that goes around the back of the head to be chafed, and touching earth occasionally.

As for the Nanocom, I'm not at all sure it will display oil press.

Seems to run fine and next time I start her up the light goes out as it should.

I'd been led to believe that the Nanocom would display oil pressure but have not found that either.

Could someone please me (idiot) steps to navigate the Nanocom to oil pressure. Not where I would expect to find it in "Instruments".

Thanks!

Nanocom wont display oil pressure. The sender is only a switch output.

Does it flicker only at idle?

Yes, idle will be when the pressure is lowest. But the symptoms would be more regular I would think.

My oil light used to flicker at idle, I ended up putting in a proper gauge so I could see what was going on. Idle psi was a constant 8+psi.

I now only run 10w40 - it now never drops below 15. Never going back to 5w30

What our German friend calls 5W Dumbass.... I run Penrite HPR 10W40, Won't go back either. Reminds me, due for a change soon.

Thanks for your reply.
No, it doesn't flicker. It either stays firmly on at any revs or firmly off as she starts.
I think that's a failing of the Nanocom. Plenty of info I have no understanding of but this basic need is not addressed.

Thanks for the illustration. I'll have a look.
Under and behind the turbo. I have an embarrassing oil leak whose source I have not been able to locate, but in that vicinity. I am leaning towards the idea of the oil pressure switch physically leaking. Had that years ago in an HQ.
