I was reading VW forums and noticed that the Golf/Jetta/Beetle/Passat have the same HVAC blend door foam issues that Porsches do. Some users have started using plastic plugs to block the holes in the blend doors. The size and number of those plugs looked very similar to the Porsche blend doors, so I ordered as set…and they fit!
I put together a quick video fo the installation process. Hopefully someone else finds this useful/helpful.
