Boxer software update

Dear all,
The Caravan club has an 10% discount offer on for Witter Towbars.
Mine is a Warwick XL 2018
I went to order, and the Witter site says a software coding update is advised, at £72.
Does anyone have any knowledge of this, whether or not it's an absolute requirement, and what benefits it offers?
Many thanks anticipation
Happy camping
Keith

I know absolutely nothing about this but found this on pfjones website...

"Coding

[size=31]This is the coding of the ECU to accept the dedicated system, this updates your vehicles software to run smoothly with the new towbar.[/size]
[size=31]All Peugeot Boxer Van models will not require coding.[/size]
[size=31]Coding is used to update your vehicles software in order for it to run coherently with the new towbar through the dedicated electrics."[/size]

Hi 
    These software updates usually mean that the base vehicle recognises, when a trailer is plugged in, it will usually turn off  
the vehicle rear fog light, show a dash warning when a trailer light is defective.
