I would like to remove the Trailer module from my 2015 Audi SQ5. I found a few guides to add the module but they seems to be all somewhat different.

So I probably need to remove the "Hitch installer" options from a few modules like Engine, ABS and Cent. Elect and Back-up Cam. If I forget some modules, I will simply get faults that I can then fix?

What would be procedure? Do I disconnect the Trailer module before recoding the others module? From my understanding, I should also remove the module from a gateway. When I should do this? At the beginning? At the end?

Finally, should I disconnect the battery at some point? How reset everything to make sure there is no faults?

Many thanks!
