Today I saw a (according to the rear lettering) A8 (D2) 3.3 TDI, who was walking at the front of the windshield a green environmental badge!
Is there a particle filter for this rather rare model? Otherwise, I can't imagine how this one comes to a green badge!
Of course, whether it was a 3.3 TDI could not be determined from outside. But it was definitely a diesel based on the tailpipes pulled down! Would there be an alternative filter for the 2.5 TDI?
I was a little confused...
