Hi,

I have a new Skoda Superb Mk4 (2026, MIB4 infotainment, software version 2768). Today, the car went offline in MySkoda, and the globe icon in the infotainment turned grey. Important detail:

• The car is usually parked in underground level -2 parking, where the mobile signal is extremely weak or nonexistent.

• After taking the car outside and driving it for a while, it still remained offline.

Current symptoms:

• grey globe icon

• remote services unavailable

• car shown offline in app

• no SOS/eCall errors

Has anyone experienced this after losing LTE signal in underground parking?

Does the OCU/telematics module sometimes get “stuck” and require:

• infotainment reboot,

• deep sleep,

• or dealer reset?

Trying to understand whether this is:

• a common MIB4/software/backend issue,

• or something worth checking at the dealer already.

One more important detail: disconnecting the 12V battery and reconnecting it completely solved the issue temporarily. The car immediately came back online afterward. However, the exact same problem returned the next day in the same scenario:

- car parked on underground level -2 with no/very weak signal,

- then remaining offline afterward with a grey globe icon.

This makes me suspect the telematics/OCU module may be getting stuck after signal loss, rather than this being purely a backend/server issue.

Thanks.

I am a former Skoda owner these days, but my Seat Leon PHEV (which I think has similar systems to the latest Superbs) had a "grey globe" after I parked it in a car park for several hours where there was no signal. I don't park there regularly but after I'd left it took a long time (nearly a day?) for the white globe to come back.

The rest of the thread may be useful to you too if you've not seen it yet.

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?

I wonder if there's an option in the infotainment to turn off remote connectivity when you park if you know there's going to be no signal, to stop it trying to connect and failing? You'd lose remote access to the car (but you may not have that anyway) but it may be happier to connect when you come back?

Thanks, @DavidY , I will have a look at the thread. In the meantime, after disconnecting the battery twice, I haven't encountered the issue anymore. It's been a week or so since then.
