Strada Heating Inadequate Output

Heating issues are frustrating, especially on a newer vehicle. A defective water valve seems likely given the error code and symptoms. Did you check the coolant level? Low coolant can mimic a faulty valve. Also, inspect the wiring and connectors for corrosion or damage, as a loose connection can trigger error codes and impair the valve's function.

Thanks, I checked the coolant level, and it's fine. I also checked the wiring and connectors, but I didn't see any corrosion or damage. Should I replace the water valve, or are there other tests I should do first?

Replacing the water valve seems reasonable, but without better diagnostic tools, it's hard to be certain. To avoid misdiagnosis, I'd suggest a qualified technician at a workshop. They can test it properly and confirm if the valve is the problem, which will prevent unnecessary costs.

Thanks for the guidance. A technician confirmed the water valve was defective due to a faulty electrical connection inside. The repair, including the new valve, cost 95€. The heating works now, and the error code is gone. Thanks again for the help.
