Skoda Octavia Heating Issue

I am writing to report an issue with my 2013 Skoda Octavia, gasoline engine, with 118774 km on the odometer. The heating output is insufficient, and an error is registered in the error memory. The diagnostic suggests a defective water valve, potentially stemming from a faulty cable or plug connection. Could this be the cause, or should I investigate other components such as the heater core or potential engine overheating?

I encountered a similar situation with my Volvo V70, albeit a different make. The reduced heating output and error code pointed towards a potential valve blockage in the engine coolant system. It's like a kink in a hose restricting the flow. Have you inspected the cable and plug connection to the water valve as suggested? A loose connection could easily manifest as these symptoms.

Thank you for your response. Regarding the cable and plug connection, is there a specific area I should focus on? Are there any telltale signs of a defective connection, such as corrosion or loose wiring?

Yes, precisely. Check for any green residue indicating corrosion. Also, ensure the connector is firmly seated. However, given the error code and the symptoms, it is advisable to consult with a qualified workshop. A valve blockage, if present, might require professional intervention to avoid further complications within the engine coolant system.

I appreciate you sharing your experience. It seems prudent to have the water valve addressed promptly. The workshop confirmed the diagnosis: a faulty water valve. The repair was executed for 95€, and the heating system is now functioning optimally. Thank you for your assistance.
