The A/C evap on my E 320 T failed just one year after the warranty expired (M.B.s are warrantied here only for ONE year). The dealer offered to split 50/50 the cost on labor and parts to replace it with an original unit(copper/alluminun), so I decided to go to an independent shop and have a full copper unit installed.

The A/C evap on the S 500 L died just one month before the warranty expired, so the local M.B. dealer replaced it free of charge (labor and parts) with an original unit which have not yet failed (knock on wood!).

The full copper evap installed on the E 320T was imported from Germany but cannot remember the name of the manufacturer. I should find out next week with the independent shop and let you know.

The all copper evaporator is made by ACM.

I clicked on the "Buy Parts" link at the top of the page, and this website sells them for $800 for your '92 300SE.

I could never live in Atlanta, just because of how much the dealer charges to work on cars!!! Here in N.C., the dealer charges $80/hr. The Rolls-Royce dealership in Winstom-Salem doesn't even charge $110/hr, I think that something is wrong here.
