Citroen C8 Low Heating Output
Summary of the thread
A 2008 Citroen C8 diesel is experiencing low heating output, with a diagnostic tool indicating an error. The suspected cause is a blocked water valve, potentially due to a defective cable or plug connection affecting the engine coolant system. A similar issue was resolved by addressing the water valve, and the presence of coolant fluid near the valve suggests a leak. The recommended solution is to have the vehicle inspected by a mechanic to confirm the issue and prevent further complications, which led to the replacement of the water valve.

Thanks for the quick reply! I did see a little fluid near the valve. Can you remember the error you saw, or anything else that might help me figure this out? I want to avoid making things worse and keep up with maintenance.

If you're seeing coolant, that might be it. I can't remember the exact error code, but it was linked to the heating system and the engine coolant. Since you're seeing fluid, I'd take it to a workshop ASAP. Better safe than sorry with coolant leaks and overheating. Hopefully, it won't cost too much to fix.

Thanks for the help! I took it to a mechanic, and it was the water valve. Replacement and labor cost 95€. Your experiences really helped me out.

I had a similar issue with my C8 years ago. The heating was terrible, and it was the water valve. It could be blocked or not working right. Have you checked for coolant leaks around the valve? Coolant level may be low. Are you sure about the cable or plug? I can try to remember more!
