Hey guys, my R32 has had an R33 RB25DET in it for about 4 months, and everything has been great. However, whilst driving last week, the low oil light suddenly came on. Naturally I checked the oil level straight away, and it was fine. When I first noticed it, the oil pressure gauge was reading where it always would too. When you first start the car, it’s off, but give it 5 minutes and it comes on - and from there won’t go off. My mechanic removed the sensor and cleaned it, but this did not fix it - they were flat out, squeezed me in to replace the rear HICAS arms, but you get the idea. Below is a picture of the gauge, with precisely what happens. The oil pressure gauge appears to work fine still - it moves between about 3.5 and 5kg depending on the way it’s driven. Now what I can't for the life of me remember, is if there is just the oil pressure sender, or an oil pressure sender, AND an oil pressure switch. If it’s the latter, I guess I should replace that switch, but if there is only one, could it be a cluster issue perhaps? Some people would say just leave it, but I’m not keen on getting accustomed with warning lights on my dash, because I may miss one which shouldn’t be ignored. I am planning on running an aftermarket gauge, but I'd rather fix these issues as they come. Any help would be greatly appreciated
