Weird engine noise on cold start -- can anyone diagnose?

rawdenim · 11-16-2014, 03:50 PM

Just got my M back from the shop to get it's starter replaced. That night when I started it I heard a awful ringing noise from the engine. This lasted about 20 seconds and then stopped. When it stopped the engine sign came up on the check control and the service engine soon light popped up. Here's a video I took of the noise. Does anyone have any idea what this could be?

Not sure about the noise but you definitely want to change the oil cap.....the seal is done and it appears to be leaking pretty bad. GL on the noise diagnosis........Phil
