oil pressure sensor or switch
Happy New Year!
1991 535i (M30) - This has only happened once, but earlier today I as I shut off my engine, the dash display said "oil pressure sensor" "see owners manual".
It has been cold (14 F last night and 24 F now). The car had not been driven for 2 days (battery having problems in cold weather and had to jump start).
After I got the car started and let it idle for a while I took it for a drive and it ran fine. The oil pressure sensor message came on as I shut it off. Later on, I took the car for another drive and did not get the message again.
So anticipating a problem, I have searched on an oil pressure sensor and have not been able to find one. I have found an oil level switch, is this the same thing but different terminology?
