Skoda Roomster Overheating Problem
Summary of the thread
A 2011 Skoda Roomster with a gasoline engine was experiencing overheating issues and taking a long time to reach normal operating temperature, with the cooling fan running excessively. The problem was suspected to be related to the thermostat cooling circuit motor or a defective map thermostat. After consulting with others and taking the car to a workshop, it was confirmed that the map thermostat was indeed the issue. Replacing the map thermostat resolved the overheating problem, and the engine now heats up normally.

Thanks for the quick reply! When you say 'thermostat', are you talking about the main thermostat, or is there another one I should be looking for? And where exactly is the temperature sensor located? I'm not super familiar with the cooling system on this car.

Yeah, sorry, I should have been more specific. I meant the map thermostat. In my Renault, it was a combined unit with the regular thermostat. As for the location, it's usually near the thermostat housing, where the upper radiator hose connects to the engine. Honestly, if you're not comfortable poking around, I'd recommend taking it to a workshop. Overheating can cause serious engine damage.

Took it to the shop like you suggested, and you were spot on. It was the thermostat, or more specifically, the map thermostat. They replaced it, and the overheating is gone. Engine heats up normally now. Cost me about 350€, but worth it for the peace of mind. Thanks for the help!

Sounds familiar! I had a similar issue with my old Renault Megane. It would take ages to warm up, and sometimes the cooling fan would go crazy even when it wasn't that hot outside. Have you checked the temperature sensor? That could also be the culprit, but from what you're describing, it does sound like the thermostat.
