Yes there is many vehicles being done already...some people are not active forum members.

I'm in Colorado...there has been multiple ID.4 updated and getting out of the door. Tomorrow I'm heading to CA ... i will have to stop in NV also for 3 VW service departments to provide some assistance.

That is what we heard last year but I wonder if this is the way they are doing the current update. Maybe @VW TECHNICIAN can shed some light on the process.

More law strict countries like US took more time to make sure all hardware parts in question are observed or replaced for future OTA. And it gives VW service departments learning courses for technicians to get more experience working with ID family of vehicles. EU will always be first for all future updates before is going to be ready for other markets.
Same way other manufacturers are doing.
Example Tesla is doing first US before the other markets in World.

So the dealer went 2.1>2.3>2.4>3.1?
Also, at what point, if any, did they do this OTA, or was it all done by download?

All are done with ODIS tool connected revision 3.1.

So we have never had a successful OTA update on any cars sold in the US.

Future software update will be available for OTA.

This is what a VW tech wrote today on Facebook:

"I just finished a 1st edition. It took me 5 days to muddle my way through all the complexities.​

BTW - the update is multi part.​

1. install 32gb update with USB stick to infotainment.
2. replace 12v battery with (less aH but more CCA)
3. connect scan tool and update 34 control modules
4. force a CAN BUSS sleep
5. now go back and code, parameterize, adapt, and set basic settings of all 34 control modules
6. another CAN BUSS sleep
7. now program the 12v to the car and manually set basic settings of a few systems.

"This is BY FAR the biggest and most complex update done to any of our cars. I can understand VW wanting us to stop if control modules get bricked. With the chip shortage who knows when a replacement will get there????"​

​

No details about having to step through multiple updates, but perhaps he glossed over that part? @VW TECHNICIAN does the update entail a multi-step 2.1 > 2.3 > 2.4 > 3.1 upgrade path, or has it been condensed down to fewer steps?

Module firmware updates are done by ODIS tool>>> can buss sleep is necessary in order to do firmware updates but this is initiated by ODIS automatically while firmware updates have been going from one to another module. Software side that is visible to the user is done in one step, this is why this has 32 Gb.
Module getting bricked are possible. And this is quite complex and difficult for many technicians without experience and knowledge.
