Hi all-
I have a 2013 135i 6mt that's all stock. I've recently been hearing a metallic clanging, rattling sound at low RPMs. Sounds kinda like metal-on-metal, or a heavy dragging can or something. I only really hear it at low speeds/idle/low RPMs.
Repairs i've had done in past 6-9 months have been a new transmission (thankfully warranty job...) and a fix to the engine harness.
Here's a clip of the sound I recorded when the car was parked. Starting at :04 (and at :22) when you can really hear the sound, i'm holding the car at about 1000 rpms.

Any help would be so appreciated! I'm in my extended year of CPO warranty so I'm trying to get a vague idea if this will be covered or not before bringing it to the dealer.
thanks!!
