S40 Diesel Cooling Issues

Has anyone experienced cooling system issues with their 2007 Volvo S40 diesel? The temperature display seems off, the check engine light is on, and it takes a long time to warm up. It currently has 77442 km. I've checked the cooling grille visually. Could a fuse cause this?

I had similar issues with my S40 diesel. It was restricted airflow around the cooling grille. Never thought of checking a fuse though. Was the engine working harder than usual, especially at higher speeds? How's the coolant level?

Yes, the engine seems to work harder at higher speeds. The coolant level looks normal. Can you tell me more about the restricted airflow issue? Was it a simple blockage?

My restricted airflow was a partial blockage of the radiator fins. I took it to a workshop. I'd advise getting yours checked out, it may be the same thing.

Following your suggestion, a local workshop confirmed my cooling grille was restricted. The repair, including cleaning and inspection, cost 52€. The car runs smoothly now. Thanks!
