In my mindless spending spree, I just discovered the CLS has these little displays on its a/c controls.
Would these fit the W211??

modelupdated 2way heater controls with digital display do fit and will work (after proper stardiagnose coding) in pre 2007 W211s without digital display.

4way climate controls in 2way equiped cars ends up with some failure codes and problems.

greetingz,

Ya, it's kind of ridiculous how the V6's, pre-07, came with an analog system. I remember back in the day, at one point, they all had the same fully digital controller. Below is the unit I'm referring too:

Diesel Benz

I believe the old digital system is more analog than the older W211 analog one is. Analog type of user interface is not bad at all but in this case I guess people refer to the digital display mostly.

Anyway, the old auto AC is only an option for cars like W210, W140, I guess many others while the standard AC is much more limited by functionality in these cars, not only because of a missing digital temp display.

gaazmon

Ah, I see, so it's just the display that is digital. In the states here, the 96-99 W140, W210 E, & W208 CLK, and even the late model W202 C-classes came with this unit standard. I liked it a lot, full auto controls for both sides.

Diesel Benz

Well, since it has the diagnostics features etc. it must have a microcomputer too but a lot less sophisticated naturally than more modern control units.

After all, as long as one is capable of performing the assigned tasks, it does not matter how the device is implemented. Microcontrollers are often used to achieve cost savings too, not only enhanced performance or features. Personally I admire most those old engine parts where things like thermal compensation are done with mechanical structures.

One gripe I have with MB climate control is why is there not an option to make it sync both sides to the same temp when there is only one person in the car? All Fords and even Chevrolet pickups have this option...

Polar Bear

With that said, can the 2003-early 2005 version with the REST feature be added to a 2006MY car?

Diesel Benz

Fixed on the W221, even more an issue with 4-zone AC. I assume it appears on later models following W221 but I have not checked.

I love the REST feature, big reason I picked 04 over 05. Use it all the time.

Miss the activated Charcoal filter in my early 2005 (which does have REST).

RDSBENZ

I want these option too.

Our 2004 V6 has the four-zone digital feature ("Thermatronic" ?), so this might not be a V6 vs. V8 thing...

konigstiger

4-zone climate control offered as an option for e320, e350. What I think gaazmon meant is in MY07 the 2-zone standard control unit was redesigned.

murman

Ah.

Certainly W211 climate control unit is a step back from W210. Digital, clearly visible at all lighting conditions, charcoal filter. I hope W212 will have some improvements and at least reaches level of CLS.

gaazmon

Agree, that unit was the best. REST, charcoal, and it had true dual zone like in the E500's where not only can you control tempreture on both sides but also different areas/angles to blow from on each side (top, middle, or bottom), unlike in the E320's and E350's where it has to blow from the same area on both sides.

I like the charcoal feature too on the CL. *******g little cost cutting that kills what MB is really supposed stands for... Over Engineering. That's what an MB is supposed to be, over-engineered. That's the way we want them . *Sigh, I miss my W140

Murman, the V6's in the US from 03-06 had analog display and not true dual zone but just dual tempreture. The 07+ V6's are the same as the 03-06 except it has a digital display but is still not the same as the one's on the V8's, which are 4-zone as well besides being true dual zone.

Polar Bear

That really is a great looking interior IMO. I loved the W210.

gaazmon

Yes, the that style interior in the W210 and W208 was very nice IMO as well. I loved my W140 interior.

What are the Rest and Charcoal features? I almost want to say I think Rest is the feature the older W211's had that kept the A/C blowing when the car was off for a little while?

I actually kind of don't mind the A/C setup on the pre-07's in comparison with the digital display on the '07+ V6's, I guess it's one of those things where I wouldn't mind having digital, but not having it doesn't really bum me out. I wasn't a big fan of the display graphics too much on the digital ones also, kind of plain.

Bullseye, right on target. The charcoal is like the recirculation button to keep outside air out, but for more "smelly" conditions.

K-A

Ah. That's weird, I always thought A/C doesn't work properly (or at all) unless the motor is turned on.

Also, is the charcoal feature the one where you press the recirculation button down and it closes all the windows, moonroof, etc., then opens them back to their exact positions when you let go? If so, did they discontinue that feature after a certain year?

gaazmon

That's tunnel mode. Charcoal is an extra filter that the higher end models come or used to come with. Our CL has this on it.
