Scirocco Central

I have a 2008 2.0 GT and want to replace the discs and pads but GSF have about 3 different sizes for both front and rear, and also pads with or without wear sensors. What size discs do I need pls and is there an easy way to check if my pads have wear sensors?
Thx

Double check but I believe the 2.0 TSI has 312mm discs on the front and 256mm discs on the rear. Front pads have a wear sensor on one of the pads, rear pads don't have wear sensors.

Another thing regarding the front pads, the 288mm and 312mm discs use the same pad.
