Has anyone experienced issues with the seat massage function? While driving on the motorway, the passenger seat massage feature suddenly stopped working in an unfortunate way—the air pockets in the lower back remained inflated, making it impossible for my wife to sit comfortably. Is there a reset option or workaround available to resolve this issue?

Lumbar support adjustment controls located on the seat does not work?

Basically, yes

Seem they are broken, there is no emergency deflation system or anything like that built in. If the massaging function does not work at all from the infotainment menu and you cant do anything with lumbar support controls then you need to go to the dealer for warranty repair (seat replacement in practice).

Car in workshop while dealer tries to find out what to do. They think software issue and have referred to Skoda tech... This is day 3 in workshop.

Day 7 in dealer workshop (including the weekend when obviously no work is done). They received long list of checks to work through from Skoda yesterday.
