W639 Air Con/Climate Upgrade

Yes well that is the overhead control, does it look identical with the alarm sensors?
The rear auto climate is digital and will replace the hole unit.

Hi
Sorry to jump on board this old thread but looking to do the same conversion on my 122.
Zenman any chance you could message me with costs involved.
Thanks

Hi zenman63 as the messaging on the new forum is not working yet, could you please email me to: david.glk @ mail.com - I'm interested in doing the same (changing to digital controls) for my W169 - I have the standard a/c, and the rain sensor, and I retrofitted electrochromic RVM (using OE loom, the plug was active in OCP).

Hi all. Sorry to drag up an old thread. I have an xlong Viano with front digital climate and rear AC with manual dials. I've owned it since February. It ALWAYS blows hot air. No matter what. Even if it's switched off. Can anyone give me a hint what to do? @zenman63 you seem to be the expert...

I've had the AC pipe joining the two systems under the van replaced recently as it had a hole in it. I was told it was holding pressure and the system briefly blew cold. But no more.

I'm melting in this weather and I really need to drive 2 hours down the M4 on Saturday!
