Pixo power window failure

I also own a Pixo and had a similar problem after disconnecting the battery once. It sounds like the window regulator might need to be re-initialized. Did you try any reset procedures?

Re-initialized? No, I haven't. I wasn't aware that was even a thing. What does that involve? Is it something I can do myself, or does it require special equipment?

Yes, it's a common issue on some cars after power loss. I couldn't sort it out myself, and ended up taking it to a workshop to have it reset. They probably have the right diagnostic tool to do so.

Thanks for the advice. I took it to a local garage, and they confirmed it was a window regulator initialization issue. Cost me 290€ to get it sorted. At least the windows are working again.
