Car is 2 1/2 years old, but this has just started, turning on the heated rear screen turns off main multimedia screen. Turn off rear heater and screen comes back on! If I'm playing radio while doing this it just fades away or when I turn off the heated screen the music slowly fades back in, hard reset of multimedia screen fixes it short term but it randomly comes back,

I did have sunroof drains modified as recall, but had no issues before that. But if you haven't had it done might be worth doing as it's obviously been an issue on some vehicles.

I have same model, all windows clear quickly at all times, just push ventilation control button for windscreen demist (ac on).

Discovered that I get a "battery not detected" message and car won't start if the car fob is in the same pocket as my mobile, separate pockets and all good!

“https://www.skoda-storyboard.com/en/innovation-and-technology/technology/10-tips-on-how-to-use-air-conditioning-properly/ I suspect the a/c controller thinks it knows better than you what you want, I think you can use OBD to increase both cooler and fan output. From above Skoda link: "If you want to be sure you’re making the most beneficial use of the air-conditioning, your best bet is to keep to a temperature of around 22 °C. When it’s really hot, perhaps go for an even higher temperature so that there are no shocks to the body caused by the big difference in temperature when you get out of the car,”

While driving in snow today I had a dashboard indication/symbol for lane assist not ready. Stopped and turned engine off and back on and fault cleared. I don't have lane assist fitted, any ideas what's going on, Water ingress somewhere?

Stick one of these on it? (Sorry).

I'd visit an independent sunroof repairers first for quote, that's probably all your Skoda dealer will do, but then charge you £'s for doing so.

Does high functionality not refer to the quicker reaction times (quicker to illuminate on and off) for LED over filament lamp?
