Peugeot 301 solar sensor fault

Experiencing an irritating issue with my 2018 Peugeot 301 diesel. The diagnostic tool shows a fault with the solar sensor, and the heating output is surprisingly low. I've checked the visible connections, but can't see any damage. Has anyone else encountered this?

Hey! I think I had something similar happen with my 301. Was getting weird heating issues, and it turned out to be related to that daylight sensor. I remember reading that a defective cable or plug could be the culprit. Have you checked the wiring harness thoroughly?

Thanks for the advice! I gave the cables a quick look, but didn't go too in-depth. Do you recall any specific areas on the harness that are prone to issues? Was it a pain to get to?

Honestly, I didn't dig too deep myself. I just wiggled some wires and the problem persisted. I think it's best to bring it in. My repair cost about 95€. Good luck!

Thanks so much for the information and your experience! I think I'll take your advice and get it booked in at a trusted workshop. Much appreciated!
