Which one of these platforms is better suited to handle the changes implemented by the emissions modification?
I had assumed Gen 3 is better equipped because the Adblue dosage increase could account for most of the emission mitigation. However, the fact that the Gen 3's get so much more hardware replaced compared to a Gen 1 makes me wonder if the update is actually harder on those cars.
- Why do Gen 3's get a new DPF while 2010+ Gen 1's do not? More soot concerns?
A fair amount of people report no loss of torque while still getting phenomenal mpg's (45+) on the Gen 3's while a few people have lousy results.
The Gen 1 results seem to be consistent, a little loss of power and a little more loss of mpg's.
I know for my JSW, the fix was garbage and it took a Malone tune to restore the great driving characteristics but the mpgs were never the same.
Since the Gen 1's don't have Adblue, all they could do was retard timing (reducing NOx but increasing soot) and making the car use more post-combustion fuel injections to more frequently raise EGT's.
I assume the Gen 3's do some of this as well but they have the extra variable of Adblue to perhaps minimize the need for those other strategies.
Anyway, that's all my armchair engineering opinion on the matter.
Also as for ride quality, how does a GSW compare to a JSW?
I had a JSW so I'm very familiar with it's feel. Don't have much time driving a GSW. Never had a chance to drive a stick GSW. I hate the way the DSG feels in these cars so that clouded my impression.
