C200 CDI w203
climatronic

Hi guys!

Who has managed to change the a/c control from the analog buttons to the digital display controller. I am talking about a w203 sedan and not coupe. I have read people changing it in a coupe using a certain climatronic (from the older generation)! So anyone managed, once again it is a w203 sedan! Here in austria, i have been told, one needs to change the entire A/C which makes it damn expensive!! Another question, can the temp be shown only in °F or also in °C?

Thanks for your help

greetings from vienna, austria

Rumman :p

It should be possible.

However, there have been some problems on Coupes when making the switch because Mercedes changed suppliers for the unit sometime in 2002. Make sure you get an older one or it probably won't work.

Search the forum for part numbers (to determine old vs. new), etc.

Cheers, BT

It should work on your Sedan. The part # you need is:

203 830 09 85

If you find 203 830 02 85 it might not work since it does not work in the coupes, but then again it might work in the sedans.

Erik fixed you up with the correct part number.

Look for a user on here named MBenzNL (Steve) and ask/PM him, he's the king of parts swapping. He'll know for sure.

It should work fine, and yes, plug and play, but some people have had problems even with the correct part #, its sorta luck.

hi again
i have read through most of the threads and the people who had trouble are the ones that used 203 830 02 85...

what did you mean with people had trouble: if it is like that they were not able to use the tunnel mode then i am fine with that, i am not that bothered about the mode, main thing is that the functionality of cooling and warming is ok...

thanks, Rumman
PS: what is more advisable: getting a 203 830 05 85 or .. 09 85

The 'trouble' people had is no A/C only heat.

There is no 203 830 05 85
Its 203 830 09 85
or
203 830 02 85

The '09' works in the Coupe...however both should work in the sedan...if you can find a '09' you prob. have better odds that it will work fine.

What am I missing?

I've read where people think that simply replacing the low end climate unit with the climatronic they will have output equivalent to climatronic. Is this true? What about the extra ducting and controls for the second charcoal filter?

Hi Rumman,

As discussed per mail, I have used several 05 85 units...they worked in my father's (euro) C200K (sedan) and in a US G500 and C230k (coupe) but NOT in a US C240 (sedan).
The C240 sedan only blew cold air and no heated air at all...

The airflow can only be adjusted from the driverside selector...the passenger side selector doesn't do anything. The tunnelmode did function as far as windows go...the roof didn't react to the tunnelmode feature though.

These units automatically display degrees Celsius or Fahrenheit when plugged into a US/Euro car.

greetingz,

Replacing the stock verison with the Climatronic is primarily for cosmetic reasons. The passenger side directional control doesn't work, nor is there an activated charcoal filter.

A 203 820 05 85 was the first version of the Climatronic, it was superceded by 09 85, which in turn was superceded by the 02 85.

02 85 doesn't appear to work at all in a C230K/C240. 09 85 works in most cars (but maybe not in California ones according to CitronC230K_03's parts guy). The 05 85 should work, but apparantly not in every car (although people have been able to make this one work in a California car). My impression is that for some reason, it is just luck of the draw if the 05 and 09 versions work or not.

Cheers, BT

i was unable to get the older generation unit to work in my coupe. i had a unit which ended with 09 85, and it just blew cold air out of the defroster vents no matter the setting. i couldnt figure out why it didnt work, i installed 4 times before i sold it. i havent heard any ocmpaints so im assuming it worked for him. my car was built dec. 19, 2002. id be guessing so i have no idea why it didnt work!

I thought it didn't work becuase you had a CA car?

thats what one dealer told me. but a CA C240 w/ climatronic or a CA C320 w/ climatronic had 09 85 parft #'s before they were superceded. thats what didnt make sense. another dealer told me it wasnt possible at all, one told me that it may be because my production date requires a 02 85 model, but i dont want to buy one and not be able to return it.
