Not sure what that image is of?

Raise your rpm slightly, if the chirping speeds up with the revs, probably a belt or pulley. Also should be fairly easy to track the sound. Belts are up in front between the block and the fan.

The front and rear main seals are known to make a chirping sound when the PCV valve has issues, and or the seals are failing. Might look into that as well.

Mine has a cold weather startup chirp that goes away with warmup. Ill mention it at next service.

Could be a pulley. Does the chirping happen with the AC on only? My e36 does this and it's a broken bracket. Also, $450 sounds steep. I did the belts/pulley/tensioner on my e90 for under $200 and it took 10 minutes. Not sure what would be different on the e82.

Parts are about $200, labor if you DIY, is free. As far as DIYs go, this is an easy one wrench job.

That clip sounds like a bad pulley.

I have the same noise, N55. I replaced, tensioner, belt and all the pulleys and the noise is still there... grrrr. Dealer tells me its cause of OFHG leak, replace OFHG and OFCG and another new belt. Still there.

I thought it was a seal, but the videos and description don't really match my issue as far as I can tell. It's pretty frustrating, gonna have to make an appointment with the dealer, again. lol

I've got a rhythmic chirping or squeaking sound from the engine compartment.

Any ideas?

Edit: updated video

Does it go away after warmed up?

And no, it got worse when it warmed up.

Did you get rid of the sound?

What was the diagnosis on this?

Thanks!

In my case it was a leaking oil filter housing gasket. Oil leaks on the belt and it’s squeaks. Then you need to do the OFHG, belt, tensioner and pulley.
