And no W140 post would be complete without the input and well admired technical advice from Mr. Jim Forgione. Doing well, thank you! By the way, your personal JimF C140 page is to me one of, if not THE best site related to W140 maintenance and advice.

Eleven years with your original evap? Definitely buy a lottery ticket for me too, your luck is undisputable. Although, to tell you the truth, there are a couple of early production W140s here (a 1993 and a 1995) that have never had their evaps changed either.

But that is definitely the exception to the rule. Most W140s I know of here have had there evaps changed at least once. Tthere are a quite a few that have had them changed twice. My tech recommeds the full copper evaps as mentioned on my earlier post, and he says that NONE of the W140s where he has installed them have come back with trouble.

About the question of which W124s have the combination copper/alluminum evaps, I really do not know. My 1995 E 320 T had it and, of course, failed. My previous 300TD and 300TE never gave me any trouble with there evap units.

To add to the original topic of this post, I am into my third servo assist pump for the doors and trunk. To me this is weakest point on W140s along with the evaps. And those things are not cheap!

In terms of the engine wiring harness, I understand the M119 engine is not very susceptible to failure (although not completely inmune); as on the M104s fitted to S320s is a sure bet to self destruct up to late 1995 model year.
