Oil Pressure Gauge Reading

[The Hairy Camper]

So my buzzer of doom has been going off for the past few days. Only when I go over 2500rpm, so I believe it's caused by the oil filter switch (or faulty buzzer of doom?).
It did start going off a couple of months ago, but I replaced a connection on the earth crowns (cleaned them up) and this seemed to fix the issue. I also replaced both connectors on the oil pressure switches.

Anyway, I bought myself an oil pressure gauge tester, to make sure my engine is ok. I read through some previous posts and tested it all this morning. I'm unsure what the levels should be for my engine though.

Readings (from cylinder head switch port):

Cold Start:
Idle: 5 bar
2500 rpm: 6 bar

Up to temperature:
Idle: 1 bar
2500 rpm: 4 bar

Can anyone tell me if these readings seem ok for a 1.9 n/a diesel engine? Should I do the same test from the oil filter switch port too? Didn't want to annoy my neighbour too much this morning.

Cheers.

Nothing wrong with those readings. Happy days.

Fantastic, cheers Colin.

Is it worth me testing the switch port on the oil filter housing also? Or should I start ripping out the buzzer of doom and installing a dash mounted oil pressure gauge?

The readings at the oil filter housing can only be better, being nearer the oil pump.

So, I managed to check the oil pressure from the switch port by the oil filter today, and got pretty much the same results.

Cold start:
Idle: 4bar
2500rpm: 6bar

Up to temp:
Idle: 1.5bar
2500rpm: 4.5bar

So pretty sure the engine is ok Guess it's got to be a ground or a faulty buzzer?

The grey switch is only a year or so old (ordered from brickwerks), so I doubt it's gone bad, but I may order another one to rule it out.

If anyone has any tips, please let me know.

Cheers.
