Thank you guys! I've got a small update. It turned out to be uncleaned battery leads. After brushing the clamps with some sandpaper the car starts reliably now. There is a occasional hiccup at the start position though. I turn the key, hear constant buzzing when holding the key at the START (not the ignition prime) and nothing else happens. It's so rare that I won't bother for now

Hello!! I've been having some starting issues with my Fabia Mk1 HTP recently. Sometimes it doesn't react to the key being in the start position. No cranking, no noise (other than the fuel pump buzzing in the back). After some fiddling with key, or a fast turn it starts and runs fine. Now, after replacing the battery the issue seemed to go away and it had been starting perfectly. Two days later it looks like the problem is coming back, but now the fast turn of the key doesn't make a difference. Also, it doesn't look like it matters whether or not it's a cold start. What could be causing this?
