I have a 2010 D5 with 205 HP but had a 2012 D3 on loan during service. It’s my honest opinion that I did not notice any difference whatsoever in performance between the two cars, I even floored the pedal in the D3 and did not notice any difference at all
. This leads me to believe that the smaller turbo in my D5 is not operating properly. I will get my new 2012 D5 in a couple of weeks - I will report my impression when I get it.
