Berlingo fog sensor issues

I've got a 2022 Citroen Berlingo diesel with about 43k km on the clock, and I'm seeing some weirdness related to what I think is the fog sensor. The error memory has a fault stored, the AC won't kick on, the washer nozzles seem frozen even when it's not that cold, and the mirror heaters are dead. Feels like a domino effect. I'm suspecting an electrical issue, maybe a bad connection somewhere. Anyone else run into something similar?

Interesting. I have a Berlingo too. Sounds a bit like the time my sensor connector had a bad crimp and threw everything out of whack. Is it only happening when it is cold?

Could be cold-related, yeah. What exactly was affected when your connector was faulty?

Basically the same symptoms you described: AC, frozen spray nozzles, and the mirror heating failed. I took it to the workshop. They confirmed the sensor was getting erratic readings, pointing to the faulty connector. You might want to get it checked out properly.

Thanks for the insight. Sounds like that's the next step. I'll book it in with a workshop and see what they say. I will post what I find.
