Hi all:

I opened the hood today to change the air filters on my E90, and found a stray plug floating around. The part number on it says its a 1452049-1. Google tells me its either a auto pressure switch cold air sensor or a parking distance sensor. I have no idea how it got there and where it should go.

I'm attaching a few pictures, and hoping I can get your help. The car recently went through smog and a window regulator change at the local 'Bavarian' mechanic.

It's the plug that goes to the hood's squat switch on the drivers side by the hood's piston. Those crimp connectors mount it to the posts that are part of the cowl your cabin air filter sits on.
