There are a ton of new 2019 GTIs with a stalling issue. The concentration seems to be with the GTI Rabbit, but plenty of S, SE, etc models have it as well. When I say a lot, right now more than 2% of the 3000 GTI Rabbits produced in the US the problem, but if you look at the cars sold and driven vs still on the dealer lots that number is quite a bit higher.

A few weeks ago after I purchased a VCDS cable I offhandedly mentioned an odd stalling issue with someones GTI that I read about. From that point I started to collect a little more information from them, quickly found a few more people, and that has since spiraled out. I got a sticky created on Reddit and started a thread on GolfMK7 to create awareness. Currently there are 30+ confirmed GTIs with stalling problems, some hitting as they drive off the dealer lot with 8 miles, most have the issue hitting 500+ miles on the clock. Most seem to be the 6MT transmission, but 3 DSG owners also have it happening.
With the recommendation to get that person to file a NHTSA report, I got the word out on a few forums and a ton of people replied.

Confirmed owners over 30 now... might be 32-33 people at last count. I've also been able to get most to submit NHTSA complaints, which as of this morning we have 18 logged for the 2019 GTI (and 5 more from people who logged under the 2019 Golf, but mentioned the GTI).

To bring the focus back on VCDS, there have been a few theories floating around. Two cars have confirmed intake camshaft adjustments stopping or not moving. This was confirmed by looking at the Intake Camshaft Angle Actual vs Specified, where actual was 60 (full lock) and specified was 10. It was so far out that and idle these cars would stall out. Camshaft swaps were tried by the VW QTMs. Other dealers are trying to look at the throttle body, but with the word on the street ramping up it looks like VW's QTMs are trying to coordinate more dealers on the problem. One of the questions that popped up was why this was happening, and if its electrical/software, we have been able to document certain odd adaptations on the 2019 GTI. One member has brought up that his car was left partially in transport mode. CAN gateway had it set to "not active" but Central Electronics had its set to "Active". His car was stalling immediately off the dealer lot, brought it back and they scanned his car and found this setting. Locally my 2019 GTI Rabbit had this anomaly and another 2019 GTI S I scanned yesterday also had the same anomaly.
2019 brought a new ECU into the mix, so there are probably some software quirks floating around. It also brought about the 508 spec 0w20 oil into the mix with some engine design changes. Right now I think a lot of people are hoping this is a software problem rather than a mechanical one.
On my personal front I've sent over my auto-scan and channel map to the Ross-Tech guys from my Rabbit and have another channel map from a 2019 GTI S to share as well for them to work on documentation.
