E46 got coded for 1-touch unlock and Comfort Access, but bad news for the 2002. Carl himself actually looked at the car today and noticed it has a 1600 head, but it gets worse... I showed him a picture of the piston top from when we changed the HG, it has some weird Euro low compression pistons. Looks like I'm either gonna look for an E12 head and some pistons/rods/crank or a new engine entirely.
