I'm a bit of an interloper these days as I swapped my last Skoda for a Seat Leon 1.5 eHybrid, but that's probably sharing a few components with the latest Superb IVs. But I found Seat Digital Support were pretty helpful when I emailed them with a "grey globe" issue, so maybe Skoda have an equivalent digital team who may help if you contact customer services? Also - this is possibly a silly question - but what is the phone signal like where you park your car? The reason I ask about parking is that I had the "grey globe" a few weeks ago when I parked for several hours in a car park with no phone signal. Even when I drove away and parked in places with a better signal, and locked and unlocked the car etc, I couldn't get rid of the grey globe. My theory was that if it can't "phone home" due to poor signal, the car stops trying to use the mobile signal after a while, to preserve the 12V battery, perhaps more so with the PHEVs. If it can't find a signal, it feels like the car gives up for a while - maybe until the next day, maybe for 24 hours? In my case the white globe came back the next day, but even then it wasn't automatic. For my SEAT there's a "Users" option in Infotainment and I seem to remember I used the option to "sync" my user account, and that eventually worked and this also made the globe white again. However this hadn't worked the day before when I'd tried it several times, and I think had not worked a few times on the second day too, so maybe this was just luck with the timing and it would have come back anyway on its own. But if the Superb has a Users option and a Sync option within that, it's worth a try? But may not work the first few times. I did also wonder if taking control and deliberately disabling those services in Infotainment for a day, and then enabling 24 hours later, somewhere with a good signal, may also be a way to reset the cycle if the car is deliberately trying to preserve the battery? But that's just an idea in my head- I've never tried it. I also think lock and unlock generally make my car phone home so perhaps locking the car and unlocking several minutes later (after everything has properly shut down) may provoke it to connect, possibly in conjunction with the above?
