Going back to the VW's the reason the performance was less once the software had been fixed was to do with the EGR, the EGR was only used on the MOT and in some cruise situations, now the software has been corrected a lot of VW's need a new EGR every couple of years where as before it was unusual to ever replace them even on cars with high mileages.
From what I understand to get a diesel vehicle to pass the latest emissions standards is almost impossible with out some degree of ''cheating'' unless you want the performance that used to be the norm for diesel vehicles.

Any motoring engineer worth their salt would know that achieving Euro 3 then onto Euro4 and onto Euro5 in the timescales laid down by the relevant standards authorities was only going to be accomplished by cheating as it was not doable mechanically/electronically. Hence the necessity to cheat.
VAG engineer says - "Over at GM their 2.0l engine is doing 205".
VAG boss says - "Right, mark ours down as doing 195"
VAG did 8% more sale during and after the howling of horror!
