Yep, I'm experiencing issues with Go Times too. Cannot remove go times, which means my car will be preheating when I dont need it to! Seems like a server side issue to me.
Have you tried editing the GO Times from the screen inside the car?
I tried editing the GO Times from inside the car. Would not save the changes I made.
Yep, same issue I had (except mine was with value charging, as I don't use GO times. Heck, for all I know setting GO times probably didn't work either). The charge time was blank when I stopped the car (usually displayed in the screen to the right of the speedo), car would charge immediately when I plugged it in, and I could not save value time entries. Initially I could also not change the treble, bass, and midrange settings, however that started working again.
All good after new TCU.
