Problems adding Cruise control to my W204 2007 C200 CDI
I have gone down the path of adding the complete cruise control column from a wrecked W204, slip ring, command column, and indicator stalk and Cruise stalk.
I have had the car SCN coded to accept the add on kit, however when I activate the control it just says "cruise control/lim inoperative.
In one of the menus in diog mode it stated somewhere inconsequential or consequential error or words to that effect, however we can find no errors listed. I know the slip ring is fine, I have changed the command unit which only leaves the indicator/cruise stalk, could this be faulty without showing errors in diog mode.
The car has had ALL known firmware updated, am I missing anything?, are there any other parts that may be needed on this model, cruise control amp etc although I am assured there should not be.

Any help would be really appreciated.
Kind regards Kevin Dawson
Did you manage to get this done? I desperately need to this very same mode in my 2007 C220CDI W204. Any clues?
I had a trip to Hilden in Germany where there's a workshop called No Speed Limit. It turned out to be a MB Dealer which also retrofits basicaly every single thing you may want on your Benz. He was extremely helpfull, the job took him about 2 hours and he could not understand why nobody knows what to do about the Cruise retrofit. He does.
It cost me a lot, 1589 euro, but it was only because I needed the ECU replacement. Depending on the car, you either need to replace it or not. Mine had to which he told me seconds after I gave him my VIN number. If you don't need to do it he will charge you 399 euro. I don't know how he can tell wheter you need the change or not, but he did a lot of MBs CC retrofit and never had a problem.
So that's it! I have my cruise control on new MB original parts and the best part is that when i asked my dealer to check once again for cruise control retrofit and gave him the VIN he was just shocked and answered: "I don't know how you did it, i don't know who did it, but my factory Star tells me your car has Cruise from the factory" :-) I simply love the way Hilden guys handled it and the factory cruise in my Benz!
Cheers,
