I checked the car and looks like the errors have disappeared. Not sure if there was another update that failed causing the issue. Any suggestions on next steps.

Keep in mind that all modules have to communicate through the ECG (better known as GWM). It is possibly just a glitch in the matrix after the update. If the codes went away and stay away, there is no reason for concern. IMO, of course.

Often when a car behaves this way after an update a key cycle or a full power cycle (disconnect 12V battery, wait 10 minutes or more, reconnect) will solve these communication issues. 🤔🐩
