Report "Hi, I have a C240 merc, elegance, 1999 model, manual. I sent my car in for a service and when it came back the oil light comes on after 15 min & continues to flash. After I park the car, it won;t start up again. It seems if I leave it for 15 min and then start it again,it starts up fine and I can drive for about 15 min until this happens again i.e oil light starts to flash and it seems the engine is getting hot and therefore won't start up again. Wonder if you could diagnose the issue ? Thx"
