Maybe as a starter, from the records and CAR DATA for my daughter's May 2019 SEAT Leon Cupra, the fronts are TRW with 340 X 30mm vented discs, PR code 1LJ or 1LG or 1LD - the printout of CAR DATA for that car lists front brakes as being PR - 1LD silver callipers - but Cupra has Black callipers, so nothing is straight forward. The rear brakes are ATE with 310 X 22mm vented discs, PR code 1KY other comments are "no wear indicator system" - or similar wording.
Edit:- as a VW Group parts listing I tend to use now only lists PR-1LD or 1LJ and callipers colours RED or Black - really for parts like discs and pads PR - 1LD and PR - 1LJ use the same parts.
