While changing my spark plugs, I cracked a plastic fitting that connects to the air intake on my S5. I've searched all over, but can't seem to find the part number. The car runs perfectly fine, but I get this VAGCOM code: 001286 - Idle Control System P0506 - 002 - RPM Lower than Expected - Intermittent

Does anybody know what this piece is? Here's a couple of photos:







Thanks
