Captur cruise control fault

Interesting issue. I own a Renault Captur and had something similar. The issue might stem from a defective cable or plug connection related to the throttle body actuator. Could that be it? Investigate the connections to see if they are corroded or loose.

Throttle body actuator, eh? Where is that located, and is it easy to get to? Anything specific to look for when checking the connections? I'm guessing it's not just unplug and plug back in?

The throttle body actuator is typically near the throttle body in the engine compartment. But, considering modern vehicle electronics, be cautious. Inspecting for corrosion or looseness is a good first step, but diagnosing the root cause might need professional equipment and expertise. For a precise diagnosis and proper repair, I recommend a qualified workshop. They can perform a comprehensive assessment and pinpoint the cause. I did this when I had similar issues and it was the most reliable solution.

Cheers! Took your advice and went to a workshop. It WAS a dodgy connection to the actuator, like you said. 95€ later, cruise control is back. Thanks for the tip!
