Citroen C3 sensor error

Hi, I have a 2002 Citroen C3, gasoline engine, with about 145k km. Recently, I've been getting a sensor error message in the speedometer, also stored in the error memory. It seems like various systems are failing, and there's a warning light on. Could it be the radar sensor? Anyone had similar issues?

Hey! Sounds familiar. I had something similar happen with my old Volvo a few years back. Adaptive cruise and collision avoidance went haywire. Was yours doing that too?

Yeah, adaptive cruise is definitely acting up, plus the collision warning seems off. What was the problem with your Volvo?

Turned out, it was just a dirty sensor. I cleaned it and the errors disappeared. Though I'd still recommend you get it checked at a workshop. Better safe than sorry with safety systems.

Thanks for the advice! Took it to the shop, and you were spot on - the radar sensor was dirty. They cleaned it for 45€ and everything's working perfectly now!
