Now that you've mentioned the electrical glitch, for it to have happened on the same day as these problems started, you'd have to think that they're connected. I've never experienced this issue you're having, but I did encounter a host of other issues when my battery ran flat. The main one was the airbag module, it registered a fault which I was able to clear but doing so wouldn't turn out the orange light it brought up. Turns out I needed to update the software on my airbag module, although it wasn't Skoda that told me this, they'd have charged me for a new module, thankfully I got some great advice from a fella on FB who'd encountered my issue before. So yeah, could be software, or electrical etc etc. From my experience though, I wouldn't really trust Skoda to help you get to the bottom of it, by all accounts they're they're much more focused on taking your money by any means rather than helping you out.
