You need to get a feel for how Germans assemble interiors. I don't know if Bentley shows all the little pieces of the dash. Start at the rear seat console, middle console, front console, glove box, under steering wheel knee pad, climate control, radio, OBC, then you can see the heater box. Remove 6 clips and some brackets, plus the air door motors to get the core. Make sure you replace all the o-rings and plastic Y pipe.
