Another A/C thread about the dreaded evaporator core replacement. There is lots of info about doing it, etc. on the various forums, but has the MB factory part been redesigned to elevate the corroding metal issue? Or not? Any difference between any of the aftermarket evaps?

There is a wide range of prices. My MB dealer wants $800 for the evaporator, after my 15% discount. Mercedesshop has two aftermarket - ACM includes expansion valve $340 and Proliance $213. The ACM part looks to be all aluminum (core piping and fins), while the Proliance part has a copper core and aluminum fins.

Thanks, Dave
