Here is how to:
Add cruise control / limiter to your Vito/Viano W639 it's configuration.
This should work for all W639 till AJ08

Tool we need:Star diagnostic MB SD Connect C4 system with DAS Developer mode 

In Developer mode :(tested version 10-2008)

In engine control unit:
Entwicklungen (Development data->F3
Password : flexecu ->F3 
Steuergerate - Anpassungen (Control unit adaption->F3 
Steuergerate-Anpassungen (Variantencoderierung->F3

VCD_Transporter->F3 
a Pop-up tells you : "Mindest eine Codiereinstellung ist ungultig" confirm -> OK 


Here you will find the option settings
write down the line that is blue.
For example : NSG or NAG_Klima_Wasserstandschalter

Now we search for the string that contains the same options + Tempomat and Begrenzer
So that will look like : NSG or NAG_Tempomat_v-Begrenzer_Klima_Wasserstandschalter
Once you find it , click it and confirm with ->F3
"Soll die Codierung in Steuergerat ubertragen werden ?"->F3
JA or YES->F2 to proceed 

Now we log out the engine ecu and go to the :
Instrument Cluster ( Kombi instrument) (Magnetti Marelli)

Steuergerate-Anpassungen (Variantencoderierung->F3
Variantencoderierung Algemeine Daten->F3
Scroll down untill you see "Limiter" set to Ja or Yes ->F3
F2 -> F1 -> F1
Ansteuerungen -> Gesamstliste aller Ansteuerungen -> 
Scroll down untill you see the line : Steuergeraet Resetten (PowerON-Modus) (FN_Reset_SG_Power_ON)
Press F3 and confirm again with F3
Now you will see the "Kombiinstrument" reboots 

Cruise control coding is added succesfully to your W639 now 

As for the cruisecontrol handle itself.
On the back of the EZS you notice there is place for 1 connector , this is where the cruise-contol handle will be plugged it.

Hope this will help any of you
