The 2021 is just fine without it.
Not if you have an AWD like I did. If I still had that car this would be the final straw. Buyback.

As an absolute minimum for cars on 2.1, VW should start a new service campaign to replace the 12V battery, update the 12V charging system software if needed for the new battery, and fix the phantom ESC problem on AWD models. Then I might agree that 2.1 is acceptable.

One thing puzzles me. Don't think it's been mentioned yet, sorry if it has.

It's been reported that most '22s were updated at the port. Could be the port of export, or import, I don't know. In any case, thousands of '22s were successfully updated to 3.1 prior to delivery. Was the success of this update due to those cars having something higher than 2.1 when they left the factory, making the updates easier? Or if they went from 2.1 to 3.1, why did it work well?

My wild guess/speculation is the weakest point in this upgrade is at the dealer level. The '22 cars that were updated at the port(s) were probably worked on by a team of factory trained specialists who really knew what they were doing.

If I have any of the '22 port update info wrong, feel free to correct me.

We don't know what the 22s started at when at the port. It could have been 3.0 which would make the process much easier.
Edited for clarity.

We know there are '22s in the wild with 2.1*. If that's correct, they definitely didn't start production of the '22s with something newer than 2.1.

*Am I correct on that?
I want to ask our friend VW TECHNICIAN if the system or certain modules use encryption, does each car have unique encryption key(s) etc. He probably can鈥檛 tell us. Or shouldn鈥檛. :)
What if VW were to put together say a dozen strike teams of trained and experienced upgrade techs and deploy them around the country to work at each dealer for some period of time to aggressively address this? It would also provide hands-on training to the dealers.

It could happen. :)
