Can anyone tell me if there is an official Volkswagen bulletin requiring the Phaeton to remove the procedures of the VW dealer’s assembly, remove the rubber stoppers from the plenum and cut off the processes of the roof? Or is this done unofficially to prevent damage caused by flooding in the rain? I have now tried to talk myself out of it and my insurance policy by claiming that it is a maintenance residue, we nn the Phaeton has not been modified. Who can help me get an answer to it? Thank you in advance!
