I'm having trouble installing the 3.8.11 software update on my 2022 VW ID.4 Pro S.
I got a notification in the app a month ago that the 3.8.11 update was ready for my car and I started the download. It took a month for the update to finish downloading and today I got the OTA Update available message.
I parked my car outside with a 73% SoC and one bar on the 4G strength signal icon. I turned off the headlights and set the car in park and pressed the park button again so the red "P" icon appeared on the screen. I pressed the Start/Stop button on the side of the steering column. I tapped the yellow "Install Update" button on the infotainment screen and then it said to get out of the car and lock it, which I did. I took the keyfob inside with me.
I waited three hours, got back in the car, and the infotainment screen said that the OTA update failed. I parked the car in my garage, which also has one bar of 4G, and repeated the steps above. Three hours later I got in the car and the update failed again.
I'm guessing I need to park it outside where I can get three 4G bars and try again? Anything else I should try?
