Depending on your VIN some cars support the folding mirrors without the need for upgrading door modules, unfortunately some of the newer Golf R's we have seen come with Door Modules that do not contain the correct PR-codes necessary to support folding function. We like to ensure each customer is provided with the correct honest advice. We simply don't want to just sell you Folding Mirrors & the switch and send you off on your way. Despite the revision being B,C,D,E they need to have the correct colour code associated. The later generation door modules also cost more than a revision B set of door modules for vehicles prior to November 2014.
We charge a flat $200 for labour of the folding mirrors, which includes the VCDS coding.
I hope this sheds some light.
