Seat Mii Heating Issue

The heating in my 2014 Seat Mii with a gasoline engine is barely working. Getting very little heat. There's an error stored pointing to a defective water valve. I'm thinking it's probably a cable or plug connection issue on the component itself. Has anyone else run into this? Is a valve blockage the most probable case?

The heating issue in a 2014 Seat Mii was traced to a defective water valve, indicated by an error code. The initial suspicion was a cable or plug connection problem, but a blockage was also considered. After replacing the water valve, the heating functioned correctly, resolving the issue.

Low heating and an error code sounds familiar. I had a similar issue. Has the cooling system been checked for any coolant leak? A coolant leak can cause problems, including poor heating and potential engine overheating. Have you noticed any coolant loss?

Coolant level seems fine, no visible leaks. Your similar issue, was it also the water valve? Did you have an error code stored?

Yes, it was a water valve issue. I'd suggest checking the cable and plug first. If that doesn't fix it, a workshop visit might be needed. They can properly diagnose the cooling system and confirm if a replacement is needed. Is risking potential engine overheating worth saving a few euros?

It was the water valve. After replacing it, the heating is working perfectly. The total cost was 95€. Thanks for the advice!
