Skoda Yeti Overheating Problem

Overheating and the check engine light coming on definitely point to a cooling system issue. Has the car been running hotter than usual? Is the radiator fan running at all? It could be something simple like a faulty thermal switch not triggering the fan when it should. I had a similar issue with my older car, and it turned out to be a bad connection to the temperature control unit. I would check the basics before assuming the worst.

Thanks for the quick reply! The car definitely runs hotter than usual, especially in traffic. The radiator fan seems to only kick in sporadically, if at all. Where exactly is the thermal switch located, and is there an easy way to test it without specialized tools?

The symptoms certainly point to a potential issue with the speed sensor affecting the radiator fan operation. Given your description, and considering my less-than-expert status, I suggest getting it checked by a qualified mechanic. It's possible there's a deeper issue within the cooling system or temperature control that needs professional diagnosis.

Just wanted to close this. Took the Yeti to a local shop, and you were spot on! Turned out to be a defective speed sensor causing the radiator fan to malfunction. New sensor installed, cooling system is back to normal, and the check engine light is gone. Total cost was around 250€ Thanks again for the help!
