Hi all, Apologies if this is a silly question but I've just bought a 2011 A5 S-Line 3.0TDi Quattro and was wondering about the rear badge. It just shows TDi above the quattro badge and doesn't show the 3.0. Is this meant to be like this or are all of the 3.0 badges getting stolen? I've looked at a lot of others online and they all seem to be the same. Can anyone shed light on this please. Cheers.
