Wondering if anyone can shed some light on a 'noise' coming from my engine bay ('04 545). Long after I've parked my car (1-2 hours today), I hear an intermittent high pitched beep/squeal coming from the passenger front side of the engine. It sounds like a high pitched beep from a tiny electronic device. It will sound for 1-5 seconds steady, go off for 10-20 seconds than on again, etc. No real pattern other than consistent re-occurance. Eventually it stops altogether - not sure when but when I come back to the car the next day it has stopped. It's been doing this for some time but I don't know if it's normal or cause for concern. Any help is appreciated!

Hello, I just found this post. I have what seems to be the same problem. Did you get a resolution?
