I don't know about fully removing, but I disconnected/reconnected my 12v a few days after taking delivery. It was suggested as a solution to an issue with the big update (the update installed but didn't fully apply) and it wasn't very difficult.Wouldn't like to have 12v issues. Looks a pig to remove/access.
Yes, bought mine July 2021, just got to 12,000 miles. Went to my garage to run a few errands, the car was totally dead. The key would not unlock the car, the car had been plugged in while I was traveling out of town for a few days. VW roadside assistance sent a tow truck the following morning, the driver rolled it out of my corner garage and took it to the dealership. When I spoke to the service department they said that they need to order a new 12v battery and it would take over one month to get the part in. I’m currently in a rental that VW is paying for.Has anyone had any problems with the 12v battery on their ID.4?
So far so good with mine, but I have heard of some other owners that had a dead battery, sounds a bit like what happened on the ID.3
