Diesel Cayenne and VW emission issue

We have both. The 14 was not impacted as badly as the 15; the 15's hesitation/surge issues are bad. In both, we've noticed some loss of performance, more in warm weather than cooler.
My 15, post fix is going on 7500 miles now and hasn't signaled low DEF yet. Dealer changed the oil before I bought it at 28K and change; I wanted to get it back to the even 5K numbers and will be changing it this week. And filling DEF.
This. Based on driving both our 14 and 15, it seems to be something in the transmission, more than the engine. Gear selection and TC lockup.
Interesting mention of the 10k vs. 5k AdBlue intervals. Post-fix, mine dropped to 5k anyway. Still doesn't seem to be that big of a deal, other than having to remove the rear load floor, wedge my hand into the spare, pop the cover and somehow add the DEF without spilling.
Really? I've never driven a '15. My '14 still seems to be affected by what seems to be turbo lag. What makes the fix on the '15 not quite as good?

1 Year with the Fix, and Trouble begins
Hi everyone,
I own a 2013 CD, and had the fix about 1 year and 2 months ago. All has been good with the fix, except the hesitation issue that is reiterated throughout this forum. Mine is similar, very inconsistent, and seems to occur on days where we have a cold front come through accompanied with a rainfall, and a temperature drop, usually from the 70's down into the 50's (live in North Florida). Religiously, when I leave my office after this occurance, the hesitation occurs. It's crazy! Anyway, on to my additional rant... Other than the aforementioned issue, all seemed to have been fantastic, until Dec. 31st. I'm driving along, and my check engine light comes on, no messages, just the check engine. Fortunately, I wasn't far from the dealership, they were open. I had an appointment scheduled for the 11th for new brakes (has 68K miles). They hooked it up to the computer, and they said it was "o2" sensor related and to keep driving unless I noticed something wrong, to call. So, I kept driving, and, well, uh-oh, on the way home from work about a week later (the 7th), the dash lights up with "AdBlue fault. Engine will not start in 200 mi. So I emailed the dealership right away. The service rep set me up with an appointment the next day. They've had it since. They did the brakes, and said that the AdBlue fault "may" be a result of using inadequate DEF and suggested a removal and drain. Cost, $850. To which I said, PROVE IT, and I will pay it. That quickly was stifled, and on to warranty replacement items. They supposedly replaced two NoX sensors. and wanted to "perform additional test drive cycles to make sure all is working as designed, and all passes self tests... And, that they have been in contact with the "Field Rep" on my vehicle." (Whatever that means) - I hope to get it back early this week... I share this, to find out if anyone else has suffered similar issues to their CD after the fix? And is this the beginnings of things to come with this "fix"? Are all of the other parts going to fail/fall apart because of the different processing of the exhaust? Ugh... BTW, I am in a 2019 Cayenne Loaner, and my honest opinion - the bean counters at VW have cheapened it. I don't like it as much as mine. (I do like the shape of the rear-end/tail lamps better, as the 2013 is a bit , well, unique...).

I have no lag now in my car; it's lazy to downshift, but the power comes on as it did when new/pre-fix.

Given the behavior change in my CD before and after having the carbon buildup cleaned during the EGR replacement, I'd bet one of your CDs has much more carbon buildup in it than the other.

When ours had the EGT's and cat replaced (at 25,000 miles!) the dealer had 6 (Six!) CD's there getting the EGR's cleaned out, several with mileage around ours.

Me thinks EGR cleanup service should be part of the maintenance schedule of all diesel engines (maybe at 4 years - 40K miles?). But I bet no manufacturer would include that because it would scare potential buyers away

EGR cleanout required in 2500 Ram Cummins

This could explain it. Diesels are back ( in Germany) according to VW.
