Clio Fog Sensor Problems

The symptoms you describe are indicative of a wider issue than a simple sensor malfunction. Given the interconnected nature of these systems – air conditioning, screen wash, mirror heating – all being impacted simultaneously, it strongly suggests a common point of failure. Have you checked the relevant wiring harnesses and connectors associated with the fog sensor module? A defective cable or plug connection could certainly explain the behavior you're observing. What's the mileage, by the way?

Mileage is at 150613 km. Regarding the wiring, could you be more specific? I'm not sure where to start looking for the fog sensor module and its connections.

The mileage information is helpful to contextualize potential wear and tear. Concerning the fog sensor module location, it's often integrated within the rearview mirror assembly or near the windscreen, behind the interior mirror. Given the error memory fault in conjunction with the other malfunctioning systems, I would recommend having the CAN bus system checked by a professional. With an estimated repair cost of 95€ it should be worth it. Diagnosing and rectifying CAN bus communication issues often requires specialized diagnostic tools and expertise.

Thanks for the advice. I suspected it might be something beyond my skillset. I'll take it to a workshop and have them check the wiring and CAN bus system. The estimated cost sounds reasonable anyway.
