slowe30 0 Report post Posted September 8, 2012 a friend has recently brought a e30 318i pre facelift and while driving round today the oil pressure light came on, immidiatly we stopped and checked the level, was good, then let it sit for a bit started it up and after about 10 seconds oil pressure was ok and everything seamed normal. ive tried searching for it but couldnt find anything about it, just wondering if theres a common failiure part or issue with these engines so i know where to start looking Quote Share this post Link to post Share on other sites
BM WORLD 1283 Report post Posted September 8, 2012 teh oil pressure sensors have been known to fail . normally they will be leaking oil around the plug. but you should get a oil pressure gauged hooked up to be sure , or try another known or new oil pressure switch Quote Share this post Link to post Share on other sites
slowe30 0 Report post Posted September 8, 2012 from what i was hearing i know the oil pressure was low, started to knock and tick. i saw alot of people have been replacing the sensor and fixing the light comming on with my google searches, nothing that actually dropped oil pressure. it will be checked out tomorrow morning by another friend due to it being at his house and me not being able to get there Quote Share this post Link to post Share on other sites
