Clio Cruise Control Failure

I own a slightly newer Renault Clio and had a similar issue. The error message and non-functional cruise control point to a problem. Cruise control systems rely on inputs including wheel speed sensors, the engine control unit (ECU), and the brake pedal position to maintain the set speed. The actuator controls the throttle. Did you check the connections around the steering wheel controls? It could also be a faulty switch. Did you do any diagnostics beyond reading the error codes?

Thanks! I checked the basic connections around the steering wheel, but without disassembling anything. The error codes didn't point to a specific sensor; it was a general 'cruise control malfunction' type of code. Was your issue intermittent, or did it fail completely like mine?

Mine was a complete failure. Given the generic error code and checked connections, it's likely a deeper issue needing specialized diagnostic tools. While it could be a disconnection, a more thorough investigation involving the ECU and possibly the actuator might be needed. I suggest a qualified workshop to pinpoint the error, considering the complexity of modern car electronics.

Thanks a lot for sharing your experience and confirming the need for professional diagnostics. I appreciate the input, and I'll take it to a workshop. They fixed it for 95€. Apparently a cable was faulty.
