Hey! I had a similar issue with my Megane. Cruise control died, and diagnostics pointed to a dodgy connection. Did you check the brake light switch? Sometimes a faulty switch can mess with the cruise control.

Thanks. I haven't checked the brake light switch specifically. Could a faulty brake light switch really prevent cruise control from engaging and store an error? Any details about the error you saw that might help?

Yep, a faulty brake light switch can definitely cause that. The car thinks you're braking, so it disengages cruise control as a safety measure. I took mine to a workshop and they confirmed it was a cable issue. Cost me around 95€ to fix.

Understood. Thanks for the clarification and the cost estimate. I'll take the Megane to a workshop to have the cable connections inspected. Your info is helpful. The repair cost gives me a good idea of what to expect.
