I have had this problem myself on my Yeti 2.0 diesel auto as the car is not used every day it was a lottery as to the car starting.
This happened a few times which fired up as soon as Green Flag jump started it.
The engineer suggested we did not use the car enough to keep the battery maintained to full charge and purchase a solar trickle charger.
The result from the charger solved the problem I purchase it from Amazon not the cheapest option but worth every penny.
Model number Visua Solar Powered Battery Charger. Ideal for Cars, Caravans and Boats (7 Watt
Even on the coldest mornings starts first try. I just leave it on the back parcel shelf and it charges in sun or cloud.
Hope this helps
Best wishes Skoda owners
