Cruise control

[Milo]

You have a B9. The M59 is the Mark2.
Lexia is the specialist siftware used by Citroen by dealers to "talk" to vehicles.
BSI = Body Systems Interface, a computer in your car that controls many of it's functions.
To be "visible" it has to have been programmed into the BSI. Different functions are programmed in to different vehicles at the factory.

I installed cruise control on my M59, but don't know how relevant the information would be to you.

Where did you get the control stalk? is it cheap enough to get from Citroen or maybe a breakers?
Also seen some people asking about switches on the clutch & brake pedals? how do i know if my van is ready to rock with just adding the stalk & then using Lexia to tell the BSI software to use it?
Anyone done this and got the low down?
