Toyota previa 2.0 d4d intermittent oil pressure

[chewysharp]

Hi all,

Im new to this site and to previas.

I have an intermittent oil pressure light come up. when the engine and oil is cold it isnt there until you put the engine under power and high revs. When the engine and oil warm up then it becomes constant on and sometimes intermittent. It has recently had a new turbo, oil change, filter and the strainer looked at and still the same issue. 

I suspect the oil pump but cant be sure.

PLEASE HELP

Petrol or diesel?

on the 2.2 diesel the oil light would flash if it was overfilled and remain on for low pressure or under filled.

It's a diesel 2.0! It's had a new oil filter, oil and turbo. Could it possibly be oil pump or pressure relief valve

Has this occurred since the oil was replaced?
