Dunno about the TDi, but my 1.8 T has a front & rear disc setup.
Front & rear pads for discs, both come as a set anyway (4 in a box - 2 for each disc)
Discs are sold seperately.
For example, for a full brake replenish, I would need 2 x 283mm discs for the front, & 2 x smaller discs for the rear, along with 1 set of front, & 1 set of rear pads.
