There are 2 screws at the bottom portion overlapping the main panel, just take them out and easily dismantle the main panel, you'll hear it pop from the top portion.. did'nt take out the seatbelt, just pulled them straight out and applied adhesives used by the upholstery guys..
I have the same issue with my wife's 300TE. Passenger side column that goes up towards roof....the upholstery started to come up. So by the two screws do you mean the ones that are visible when you open the door?
And what type of adhesive do upholstery shops use?
thanks!
