Mackhack, hahaha thanks for the clarification. now I just have to think if Ill be ok with the Air direction issue. one more thing, my car is Aussie made and Crafty's unit is, I suppose US made, would it matter with fitment and that air control direction being my car is a RHD?

also please have a look at this photo...



what is the function of the button with the "front and rear seat with arrow in the middle" and the "2 arrows" on the bottom right side of the unit? how would it function in my car? thanks mate!

Mackhack

It will work (there is no difference between Lh and Rh cars) but if not let me know and I'll check something out for you. The seats with arrow button is to switch the controls to the back seat controls to control the back seat settings from the front control. Won't work for you in your 2-Zone system.

beejAMG

hmmm...ill think about it and ill definitely let you know. im not sure if im ok with some non functioning buttons. otherwise, is there another unit/version/style other than this?




i mean with the LCD display but all buttons can work with my car. maybe from an earlier model or something.

Mackhack

Yea 2007-2009 but some models don't have the REST button anymore.

I don't understand you. You won't gain any functionality and I told you this yesterday already. The unit WILL work in your car. Right now your passenger won't be able to change the temperature in the back separately from the front and this won't add it. Same with seperate air flow control in the front for driver and passenger side. This will only work in the 4-Zone and you have only a 2-Zone and you weren't able to control it to begin with. Why would you say now some buttons won't work? Sure all 4-Zone **** won't work but you didn't have this to begin with. So nothing to be sad about it.

I think everything is discussed to death now about this conversion.

Summary:
1. it's plug and play.
2. all existing features will work.
3. No extra features will be gained. Period.

beejAMG

nah, im not trying to gain any functionality with this mod apart from the LCD screen. what I was thinking is if there is another style or version of the climate control that came out for a 2 zone that has the LCD, (later version than mine but earlier than what crafty is offering) i reckon that would work better button wise.

Mackhack

YES I JUST POSTED IT and at least 1 extra time on page 1: 2007-2009 (make sure it has a REST button)!!!!!!!!!!!!!!!!!!!!!!!

beejAMG

got it. thanks mate! ill let you know if I go through with the upgrade. cheers!

Strangely, our 2004 S211 came with a four-zone LCD unit.

Mackhack

And? What engine? Maybe a used car and someone modded it? Or it's a V6 and it came with a 4-Zone AC from the factory which was an option when W211 were still built. Your one sentence post has zero information.

murman

Well, "2004 S211" isn't exactly zero, but who's counting?

Engine: 112.949
Chassis: 211.282
Build date: 01/04

Option code 581 - automatic climate control

This is a model built for Canada.

I just picked up a dual zone unit 2008 from a guy who was parting out his car. I'm looking forward to getting it installed. I will post pictures before and after, stay tuned!

beejAMG

hi mate! is what you bought the same as this?

http://www.ebay.com.au/itm/380951195...84.m1423.l2649

will wait for your before and after pics and maybe some DIY pics as well if you dont mind. cheers!

Stuttgarten

Precisely, that is an identical unit to the one I got. I should receive my unit either today or tomorrow, seller took his time to mail it. I will be more than happy to list a DIY steps.

beejAMG

Great! lookin' forward to it. a lot of people are saying its an easy 10 minute job but I can find any DIY on it with pics. like how to remove the front molding to get to the screw to remove the center console. Im sure its easy but for people like me who hasnt done it yet, photos would really help.

another thing is the parts look identical but comes in different part numbers. i wonder if thats gonna be an issue.

Stuttgarten

I hear you, a picture is worth a hundred write-ups. I think it will take me more than 10 min as I do not want to break anything. With regard to identical items having different part numbers, I can only assume that MB has their system of ID'ing their parts for different models, e.g. the W219 (CLS) has many identical parts as the W211, but the parts numbers are not the same.

As soon as I do my the A/C unit exchange, I will put them up here!

beejAMG

sweet! will probably get the unit as well and wait for your post. thanks mate!

Mackhack

Part numbers change for different reasons. A supplier change means a new part number. If the manufacturer of let's say a control unit changes major components on the PCB the part number changes. If the software has major changes the part number changes and so on.

Mackhack

It's literally 10 minutes, and 4 screws that it takes to replace the unit. I took pictures showing where and how to remove it. I can post them if needed. Or I can post the necessary WIS documents depicting it. But the bottom line is this: it's not rocket science and once you know how to, it's actually amazing to see how these things are put together and nobody sees screws, clips and springs but a beautiful flawless interior.

+1 for pictures. You've all inspired a new mod for me.

Stuttgarten

Well, since you already have some pics. please upload them here so that everyone could take a look!

Beware for those cars in extreme heat.. when i did this swap and removed the center speaker/ AC unit assembly, the screw holes cracked..they are very brittle. The Florida heat is tough on those cheap plastic parts. When I swapped out the control unit and screwed it back into the a/c assembly I tightened the screws just enough so it wouldn't crack the plastic.. Now a week later the control unit is loose, seems like screws holding the control unit cracked.
So just be careful when removing and replacing!

Stuttgarten

Well, I received the 2008 A/C control unit this pm, SURPRISE!, but I'm sorry I'm unable to post pics. of installation as my daughter took my camera to her summer camp without telling me I'm sorry I can't post pictures.

On the other hand, after installation the A/C button just blinks red when pushed, despite putting temp at coldest possible. It blinks for a couple of seconds then goes out. When pushing MAX COOL, it displays on screen, blinks for a couple of seoncds, then goes out. I checked all connections and they're all nice and snug.

What could be the issue here. Does system need to be reset by STAR?

Reading thru the above quote, looks like version coding could be the answer. However for some it was plug and play? I don't want to tell seller unit is defective, then he sends a replacement, then I find myself with same problem.

It is interesting that everything works except the A/C button.

Mackhack

No version coding needed. The AC unit knows what it can actuate and what not. Buttons that won't work simply won't work and error codes will be stored but do not affect the functionality of the unit.
