Assuming you have also bought the Westfalia wiring kit then the install instructions are availablehere.

Have a look at page 32, you need to code the following modules:

01 Engine control unit
13 Distance control ACC
19 Diagnosis interface for data bus
34 Level control
45 Brake electronics ESP
76 Park distance control

Assuming you have a full version of VCDS there is a coding helper for each of those modules, you need to add the towing/trailer option to each. It's all pretty simple once you have it in front of you
