You've got me thinking now. I will double check. Cheers

It's worth noting that the light and buzzer only comes on when the engine is hot.

From memory I put 15W/50 in, that's what it says in the owners manual, but I can't offer much feedback as I haven't driven it anywhere yet! Sounds highly unlikely it's the oil or a blockage then as you change every year.

Just in case you don't have the Haynes, other suggestions below...

If its not electrical id go for oil pressure relief valve, Ive seen these stick in the housing from time to time after they get a little scored or sludgy.
Easy to remove in situ just take out the oil temp switch on the pump and the valve, spring and a little oil should drop out, note the order and direction of the parts!!!
Polish the exterior of the valve plunger doodah with autosol or other metal polish and clean it thoroughly.
Refit then sit back and relax as the oil light comes on yet again..

I have a vague memory of the oil pick up getting clogged and causing this problem

That's interesting, is there a mesh in the pick up pipe and I presume the sump would have to come off?

If all else fails, then this would be the next step....

I would check the pressure relief valve before removing the sump. PRV is 5 min job. I have a good used one here if yours is badly scored. It's from an S2 but I think they are the same.
However, my experience is that it's more likely faulty sender, wrong sender of wiring issue.
Hopefully see you at AITP all fixed

Yes sump off and the pickup has a mesh

[mikes2]

surely if the mesh was part blocked, you'd have low oil pressure all the time not just with high revs.

I'd wire up an oil pressure gauge to see what your oil pressure is

I've got a knowledgeable mate coming over this Saturday bringing all his kit to test.

Had another look last night only to find I had a flat tyre with a bloody great nail sticking out of it.
