D4 A8 3.0 TFSI rear brake disc size

[KungFuPanda]

I'm too lazy to jack the car up and measure the rear brakes discs at the moment so thought I'd ask on here.

ECP have two sizes of brake disc listed, 330mm and 356mm. Does anyone know which would be the right one for the above car? It's a 2011 if that helps.

Cheers

Depends on the PR codes:

330x22mm = PR code 1KW
356x22 = PR codes 1KY or 1KZ

Cheers. I worked it out shortly after I posted. £100 all in from ECP for Pagid.
