So this is a London T-charge/ULEZ issue. My 55 plate QPV its apparently Euro 3 (amazes me as my 04 plate Murcielago is Euro 4); I checked a few 2006 sport GT's and they are Euro 4. Apart from the different X-pipe (sport GT one is unsilenced) I can't see any physical differences in the engine/exhaust sections between the two cars- is it only a software issue? I'd like to get my QPV to Euro 4 if possible.. (doesn't bother me with the t-charge, but in 2021 when the ULEZ comes into effect, there is no resident discount for this).
