We were driving the 97 M3/4 last weekend in 100 degree weather, and after 30 minutes we would see the oil light (Aladin's Lamp) start to faintly glow when we stopped at a light or sign. I know, an easy solution is to ignore all traffic control devices and keep moving, but with all the CCA stickers on the car I don't want to put the club in a bad light. When we got moving again, the light would fade away, but sure enough at the next stop it would slowly come back again. The temp guage was reading north of average, but not in the danger zone. I checked the fluid levels (all OK) and checked for leaks (only car we own that is not leaking at this point) and I have put a couple hundred miles on it this week, and have not had this happen again. Is this a warning of things to come? Oil pump about to go? Should I change it now? Do I tell Bev it is about to blow up and we need to replace it with an mCoupe? Thanks for your help.
