Skoda Kodiaq Overheating Issue

Restricted cooling grille on a Kodiaq, huh? Those things can be a pain. First thought that springs to mind is the fuse, as you mentioned. Have you actually checked the fuse with a multimeter, or just visually inspected it? Sometimes a hairline fracture can be hard to spot with the naked eye. Also, is the radiator blockage only happening in cold weather? I remember on my old Passat, the flaps would sometimes freeze shut in winter, throwing a similar code. Is the radiator fan running constantly, even from a cold start?

Yeah, I gave the fuse a visual check, didn't think about a multimeter. Good point. And it seems to be happening regardless of the weather, cold or mild. As for the fan, I can't say I've specifically noticed it running from a cold start. Where exactly is the fuse located? I've been poking around the fuse box, but nothing is clearly labeled 'radiator grille'.

Okay, multimeter is your friend here. A visual check rarely cuts it. As for the location, check your owner's manual, it should have a diagram. Barring that, a quick search online should reveal the fuse location for your specific Kodiaq model year. If the fuse checks out, then you might be looking at a faulty radiator grille shutter motor or even a wiring issue. But start with the basics. If the problem persists even after replacing the fuse, I would suggest taking it to a trusted mechanic, as it may be an engine cooling issue that might lead to engine overheating.

Just wanted to say thanks for the input. Turns out it was the fuse for the radiator grille shutters. 52€ and a bit of fiddling later, and the Kodiaq is back to its old self. No more check engine light, and it heats up like it should. Appreciate the advice!
