Hi guys,

I have a 2014 320d touring xdrive. I have this noise coming through my vents. I’ve dropped hvac motor and pollen filter and al clear except a nice spider 🤮 lol
I’m super paranoid that my timing chain is rattling but there’s none of the usual tell tale signs of it?

This is the noise coming through the vents, it only does it under light acceleration

This is the engine bay.

Any help at all would be extremely appreciated as the noise is driving me nuts!

Engine sounds completely normal from the outside in that short clip. 2014 N47 would have already had the fix applied from the factory.

Does the noise stop when hvac fan is off?

Hey bud, thanks for replying. Nope the noise is there with the fans off. But if I close the vents then the noise can barely be heard. I’ve tried ac on and off recirc on and off. It doesn’t change.
