Hello!
Does anybody know, is this some kind of error or problem on my Skoda Fabia II display? I did not have this line before, but now I have it. This line appears when I tried to reset oil service, but that time my reset was unsuccessful.  Maybe some pixels are dead or something. Also, I did not have water in windshield water tank, but my display did not alert me about it. Is this somehow relate?
Thanks for a help!

Not seen this before so can't help directly but try disconnecting your main battery for ten/fifteen mins and then re-fit it. Then see if the screen comes on properly. I do know my non maxi-dot display can kind of trip out if you clean it with a static cloth. it does not blow a fuse, just trips off and the battery removal method is how to re-establish it! (Had it happen twice).

Got the same line in my Fabia
