Skoda Superb Hybrid Overheating Issue

I have a 2022 Skoda Superb hybrid. I've noticed some issues lately: the temperature gauge is acting up, the check engine light is on, and the engine takes ages to warm up. I suspect a cooling grille restricted issue. Could a defective fuse cause this?

Sounds like a sticky thermal management system. I had similar issues on my previous BMW, though it was a diesel not a hybrid. Start by checking if your radiator grille is opening and closing properly. The ECU uses sensors to control it, and if it's stuck closed, you'll get car overheating. Is the radiator fan running constantly, even when the engine is cold?

Thanks, that's helpful. How can I check the radiator grille functionality? Should it be visibly moving when the engine is started?

Yep, you should see it actuate on startup or when the engine gets warm. If it's not moving, it could be the motor, the linkage, or the control signal. Check the fuse first; that's the easiest thing to rule out. If the fuse is okay, it might be time to visit a workshop. They can diagnose the system with proper tools.

The problem is solved. It was indeed the fuse for the radiator grille. Parts and labor came out to 52€. Thanks for your help.
