Hello everyone,

I currently own a 2021 Octavia iV. The cars was bought second hand, last year in May. All the summer/fall, I didn't have any kind of issues with the infotainment system. Once the winter came, at every first start of the car, the infotainment randomly goes in the hidden menu and stays there.

If I try to go to another app, like smartlink or radio, it switches itself to hidden menu again.

It does this thing for 10 or maybe 15 minutes, and it's a pain in the **s, as you cannot control the climate, change from electric to hybrid, or anything, and also the touch volume control does not work.

I thought that it might be an issue with the SW and went to do an update, so now I have the 1989 version on it, but the issue is still there.

From a FB page, someone said that there's a "autorun" file, that might be corrupted or something like that, and that this file might be the issue.

Has anyone encountered this issue? Does someone have an idea of how I might solve this thing?

Thank you

Your problem sounds like hardware related issue with the touchscreen, probably related to humidity. Maybe it registers a ghost input in the "menu" area?

Try cleaning it more thoroughly, using microfiber cloth and screen cleaner, especially around the edges.

As far as the screen is concerned, I’ve worn multiple cloths cleaning it.

I think there is a protective film over the screen added by the previous owner, which I’ll try to remove and see if anything improves or not.

But, let’s say it registers the ghost input on the menu touch area. Why when this happens, the volume touch pad doesn’t work? How are they related? It baffles me.

Hello @Stanciu09 ,

This is know hardware issue on early-on touchscreen units! It has been solved with HDD v49!

change from electric to hybrid,

I can only help you with this problem: switch the gearbox from D to S and the car will go into hybrid mode even when your infotainment has gone crazy.

Check for a protective film, but be aware not to scratch the real screen, as it might seem like there's a protective film but there isn't.

The original screen is matte. If unsure, send close-up images of the screen and its borders.

Edit: In my view, volume control and power-on/off issues are of different source, since those controls both live on under the screen on a separate bezel, not on it.

I agree with you, that the volume control might be of a difference source, but, the point is that when it goes in that hidden menu, the volume touch pad is not working. Once the infotainment is done its magic and it no longer goes there, the volume control works.

I do not have issues with the power-on/off, as that works perfectly fine even when it does its thing, as I've tried to hard reset it, by holding the power button until the screen is completely black and restart it, but this doesn't solve it at all.

Do you know if the screen itself can be dismounted and disassembled to clean the inside a bit, maybe there are some humid spots there or something?

I have no experience in that and don't think it can be done.

The exact same thing happens to mine.

I just restart the unit by pressing the power button for a while and when it comes back it "normally" fixes it.

"normally" because i've had a couple of occasions when it kept doing it after 4 or 5 restarts and it was proper making me angry. Hasn't happened in a long time though.

I know how annoying it can be...

I've checked the screen on mine, and it had a protective film, as the screen wasn't matte but shiny. I've removed the plastic film for a while now, and hasn't happened in some days now, and the weather here was quite changing, from freezing cold -5, -10 degrees to 5 or 10 degrees.

I do not understand yet, under what conditions appears, if when a bit cold and humidity, only some cold weather, or freezing weather.
