My Kodiaq has this issue and so do two other owners, one Kodiaq and one Tayron.
The rubber of the door rubs against the metal frame makes noise like you rub your finger against baloons...ive found a solution but it requires regular lube..
The other Kodiaq owner got tape applied on the frame of the door..so the rubber doesn't touch the metal...it seems to have worked well of 6 months...the official service center did this taping.
Anyone else facing this in the new Kodiaq, Tayron, Octavia???
