If you are calling dealer about it, there are a couple of weatherstrips that are coming with it, one per side, A 000 987 16 51 RUBBER SEAL replaced with A 110 884 00 98 SEAL 770 MM AT PARTITION PANELS
There is also discussion on the Forum about the type of screws used for it. Cannot find now, but as I recall - hexhead tapping screws 5.5mm with washers, 6 per side.
