Tech Tips (Headliner Removal Installation):
The removal and installation of the headliner on the Passat can be time consuming and difficult in some areas. Properly installing the headliner, seals and pillar trims will alleviate many issues that would normally be attributed to a headliner cut to short.
All steps should be followed from ELSA. Every piece of trim the repair manual has you remove is very important to create the clearance needed to remove the headliner from the vehicle and get the new headliner into the vehicle.
This document informs of the steps of the headliner removed/reinstalled without being bent through the front passenger door with glove box removed and both front seats reclined flat.
