Diesel Cayenne and VW emission issue

Funny thing is, right after the fix, it seemed fine. Quick shifts, power on demand, etc.
Now, 3 months on... not so much. I haven't been traveling much, so I wonder if it's just the learning stuff and my driving around town only?

Has anyone noticed any changes in shifting and/or throttle mapping after a few months/miles?
My '15 seems to be getting very laggy in rolling shifts/accelerations; worst in 3rd gear, but noticeable in others. Examples: (1) Foot off the accelerator going downhill and make a left turn onto another street. Press the accelerator and it's a good 3-5 seconds before the power comes back on. No biggie there, really. (2) Rolling up to make a left turn across traffic. See an opening as you're slowing for a stop and go for it. Press the accelerator and when the power doesn't come on immediately, wonder if you've made a potentially fatal mistake. (3) Rolling up to a roundabout, slowing, checking for traffic. Tight roundabouts around here, so you're not whipping around them fast anyway, but you see enough of a gap and press the accelerator... and wait, wondering if you're going to make your merge safely. (4) Merging into traffic, starting from moderate speed... same thing. Have to anticipate the 3-5 second delay before the power comes on.

Yup, I have. There's one fun turn on my commute - It's a downhill right turn changing streets. Get all the braking done, and as soon as I initiate turn in, put my foot in the throttle.. The CD "coasts" through the corner and the power comes on after the apex. It's annoying. Really annoying. (I keep forgetting to try manual shifting or sport mode to see if that helps)

Typically, when the power comes back on, my foot is so far down on the accelerator, it revs, blows past turbo lag and goes to town. That's good for the merge... but not anywhere else!
Yeah, I have the same issue as multiple people have mentioned, but sometimes when it comes back to power it engages hard and jerks... I've also started to notice more often that I'll stop at a stoplight, be there for a few seconds, and then suddenly the truck lunges forward as if someone had bumped me from behind. I believe it's downshifting slow, and I'm at a complete stop before it actually shifts to 1st... Has anyone else noticed this?

If you mean that slight surge that sometimes happens after you take off your foot from the brake, then it is pre-fix. You'll find this behavior in all Audi 3.0 tdi cars, at least from what I read around the Internet

My CD is also slow to engage from D to R or from R to D. I have to make a point of it to just be patient and wait for the gear(s) to engage.
I never think it has anything to do with the "fix" rather just the way the Aisin 8 is designed.
I also notice the hesitation at times but for the most part have gotten used to it and put it out of my mind.

^ I also experienced gearbox disengagement while in drive after braking at a freeway entrance ramp. Not fun at all waiting almost 2-3 seconds to see what happens next. Finally moved shifting lever from D to N and back to D..

I've never noticed any disengagement, even when pulling the trailer at 3,500lbs.
Only the time it takes for the gearbox to go from Drive to Reverse or Reverse to Drive, but this is pretty much with all x-missions.

I noticed today the engine/tranny disengage happens with foot off the accelerator, not just on the brake. Just another data point.

Am I getting the runaround?
I asked about the warranty on a particular Cayenne Diesel. The Sales guy sent me this and said the warranty goes until 12/22/2024 (10 years!) How can this be? Underneath, it says out to 12/22/2020. Sales guys doesn't really know. Can someone please help me understand what's covered out to 2024 vs out to 2020?

I'm going to schedule an appointment for it, and have them take a hard look at the transmission, but it seems that it's not just transmission, but throttle mapping, too. Sport mode seems to help, but not completely.
Haven't had much time in my wife's '14 to see if it's doing the same thing and will be checking that this week.
