'08 BMW E92 Engine Noise Help VIDEO INCLUDED

SeanCon · 11-18-2016, 11:00 PM

Can anyone tell me what is causing this noise? Sounds like air leaking or something. Very strange.

SeanCon · 11-21-2016, 01:12 PM

Any ideas?

lol I was not ready for that sound, ready to just say it's normal for DI cars to tick. That sounds like something is rubbing more than any sort of boost leak. It does sound like it's happening close to the boost solenoids though. Sorry I can't help much. It does sound like it osculates.

It's like a high pitched "hummmmmm" that goes for like 5 seconds, then stops, then starts again. It's so weird.. it's loud I can hear it from inside the car. Any help is appreciated!

Try opening your oil filler cap and see if it goes away.

Likely one of your boost solenoids

Just did some research and I think you may be right about it being a boost solenoid. Thanks for the input guys

I haven't confirmed it yet. Been extremely busy. Will definitely post if I find a solution
