Did your car have <40,000 miles on it at the Phase 2 fix time? Just want to get an idea if you had the complete Phase 2 fix or just part A of it.
What I don't understand is, if otherwise identical 2015 TDI's go in for the fix, in the same general condition, and if the fix is exactly the same between both vehicles, how is it they can come out differently (some say the car is better, some say it is a lot worse)?
Seems to me there is some risk of being very disappointed after the Phase 2 fix is applied, and VW doesn't seem to want to address those that are impacted negatively.
Some who have had tunes done say there is a period of time of adjustment, and one shouldn't judge a tune until a fair number of miles are put on and the self-adjustments are closer to be near final state. That could be a factor, but if it is, it should be consistent for all who have Phase 2 done (feels bad to start, but gradually improves to a point that should be at least equal to pre-Phase 2). From a science standpoint, I don't understand how things can be so different on Gen 3 2.0L TDI's like this.
