On the first or second page of your service book, it will list the options that the car is fitted with, it is usually a printed sticker. I also have a 2011 V6 Highline, however sedan, and it was fitted with the 1LA option. Hence 340mm.

On the dba website catalogue, the "340mm 1LA & 1LB" is listed under the Passat CC, not V6 Highline. So be careful and check your service book. I think most B7 Highlines use the 340mm not the 345mm for the front rotors. The 345mm is mainly used on the B6 R36.
Thanks very much! I actually ordered 340mm by accident, meant to order the 345mm. Looks like the 340's are what i'll need as I can see "1LA" in my service book

What about rears though? Options seem to be either 2EA or 2EL and I can't see either of those in the service book.
