GLA Hybrid cooling grille restricted

I had something similar with my Mercedes, though it's not a hybrid I got the same error message, and the engine was definitely taking longer to warm up than usual Have you checked your fuses Specifically, look for any fuses related to the cooling system or engine management A defective fuse can cause all sorts of weird issues Also, is the grille itself physically obstructed by anything like leaves or debris

Fuses are a good call Where exactly should I be looking for the cooling system fuse Is there a specific location in the fuse box Also, the grille is clear of any obvious obstructions

On my car, the fuse box diagram was inside the cover of the fuse box itself Your owner's manual should have the exact location for your model If the fuse is fine, it might be worth having a workshop take a look Given the check engine light and the other symptoms, it could be more than just a fuse issue

The fuse was indeed the culprit I replaced it, and everything seems back to normal It cost me 52€ Thanks for pointing me in the right direction
