The entire front of this car has been disassembled transmission/starter/radiator/entire front suspension and brakes, and now reassembled. None of us can identify a lone bolt discovered under my bolt organizer tray. Egr is off and staying off but I don't think it's a bolt from that.

Appears to be some factory locktite applied to only the side showing in the picture. Overall a pretty clean bolt so I know its nothing from the LIM removal.

Anyone have any ideas?

p.s. this is why you write down where bolts came from too.

Key for scale.
