Managed to drop the headliner.
You need to pry all 3 panels from the center module out. The auxiliary heater panel is plastic welded to the center module so dont try to pry that one out.
There are wiring looms coming to each of the 3 panels.
There are 6 screws holding the center module to the headliner:
- 2 under the SOS button panel,
- 2 holding the inner lightning panel and under that light panel there are 2 more holding the module to the headliner.
After you’ve taken these 6 screws from center module out and unclipped every panel and unclipped the connectors you can start to pry the module from the headliner, its quite the pull. Start from the front (auxiliary heater/sos button end), pull straight down. There are 2 hooks on windscreen end of the module. After youve managed to get the module out, there are 2 more screws holding the headliner to the roof.
Mine also had 2 wires going to the rearview mirror. I twisted the mirror base counterclockwise to it unclipped and i was able to unplug the connectors.
I wanna say, bitch of a job compared to the T6 but manageable, just take your time.
