Mercedes W203 trouble code P0410 and P2036 secondary air injection fix

This is on a 2002 Mercedes C230 Kompressor Sport Coupe that I recently bought. It was in rough shape and one of the issues was the check engine light was on because of an emissions issue. There's more information here too. mbworld.org/for...
There's a really good 3D animation of the M111 Kompressor engine here: • Mercedes W203 Kompress... Secondary air injection system is highlighted at the start point in the link.
UPDATE: Success! I've put a few hundred miles on it since this fix and haven't had any issues.
