2.2DTI SRi Oil pressure light blinks

[acaetano]

Fellas,
I'm sorry for some time apart, but i was a few weeks out in work. Now i have an old issue bugging me again. At September every time i did a long or difficult trip like climbing on my SRi, the oil pressure light blinked on neutral. Running cold it never happened. A technician had measured the oil pressure and said that's ok, so we've seen the electrical part. After a reset on ECU i did some long trips (at about 500miles always running), and the oil pressure light no longer blinks. But on easter i think it had blinked once after a lot of effort to get out of being stuck on sand. What do you recommend me to do? I'd seen prices of oil pressure switch and oil temperature sensor and it's not expensive(at about 20€). Someone has another idea?

Thanks a lot,

if a mechanic has tested the oil pressure and the pressure is ok then you need to fit a new oil pressure switch.what mileage have you done since the oil and filter were changed.

this happens also when oilfilter is clogged up.

Yes...i spoke to my uncle (the family's mechanical...works on Peugeot/Citroen here at Marinha Grande) yesterday at dinner and he said that he didn't remember the exact value, but surely higher than 0.4 bar. When it happened last time it was just before the oil and filter change...I think at about 9300 miles(15000km).

I always change the filter when I change the oil, so all oil filters that were in my car didn't run more thar 9300 miles. The filter fitted in the car has 300 miles now.

I'm going to France in May 6th, and i will measure the oil pressure and change oil pressure switch just in case...it's cheap. 7€ don't pay doing that trip worried.
