Peugeot 4008 low heating output

Hi, I'm having a strange issue with my 2014 Peugeot 4008 diesel. The heating output is very low, and I've got an error stored. I suspect the water valve is defective, and I've checked the cable and plug connection. Mileage is at 177670 km. Has anyone else experienced this?

Hello, I have a 4008 as well, and I had similar symptoms last winter. The low heat and error code definitely sound like a water valve issue. Did the error message point specifically to the valve?

Yes, the error message indicates a fault with the water valve. My mechanic mentioned that a defective cable or plug connection could be the cause. Did you also check this on your car, or what was the problem?

I did check the connections, but in my case, the valve itself was faulty. Considering the age and mileage, it's probably best to have it professionally inspected and replaced if necessary. The repair cost me around 95€.

Thanks for the info! It's helpful to know someone else had the same problem. I'll take it to the workshop to have the water valve replaced.
