VW T5.1 excessive oil use

[Mtwem]

My bi turbo is 2012 number and egr C not D so updated models from 12 obviously still had C suffix

Where exactly can I find these letters to determine whether I am affected?
Cheers!

You can find it by looking directly below your bonnet catch for a metal plate with a sticker on it. The letter on the end is the suffix.
