It looks like my heated seats are coming on without being actually switched on any body had same problem 

No, my passenger seat base didn't come on when I pressed on! £360 later it works again....

That's a new one for me too - like numskull, I've had the right rear not come on but luckily that was fixed on Skoda's dime.

 

I would have thought the switch would be suspect but it sounds like you're saying more than one seat is coming on without being switched? Not just a single seat?

I have the same problem if the car is left in the open on a hot day when the car interior gets very hot.  The front seats turn on by themselves and stay hot, very unpleasant on a hot day in Australia.  If the car is parked undercover, this doesn't happen.  Additional to this issue, I have also noticed that the low heat setting is actually very hot.  Maybe the electronics have gone faulty.  I have not had any water leakage into the car.  I asked the dealer to check and all they did was reset the computer but it hasn't made any difference.

 

I would be looking at live data to confirm but that sounds like a software bug to me.
