I was staring at the parts while eating my cheerios this morning and realized I didn't fully understand what Lil Bastard was saying. The larger tab that broke off my contact spring is what cancels the turn signals - I didn't grasp that as somewhere else I had read there was an eccentric on the steering column that did it.
I've verified that my old stalks cancel just fine, and even the little nub is in good condition. I guess I can sell those used.
Still waiting on the VW dealer for the OBC hack wiring.
