Yes I'm sure its the same process as for my B8 Avant.
Starts with removing the lower bench, This involved finding where the clips were and giving a really good tug. IIRC there was one big clip per side. Also remove the isofix plastic before you attempt this.
I think the process for the rear split seat is that it has a torx bolt holding down a central bracket - if you ge tthe correct angle with the seat folded partially it makes it easier to see, this needs removing and then each side of the bench will lift out.
