Jumpy Cruise Control Fault

Strange, I had a similar issue on my 2016 Opel Astra. Different car, but the symptoms sound familiar. Did the diagnostics point to anything specific? Have you checked the fuse box or any of the connections around the throttle body? Might be worth a look before getting too worried.

Thanks for the tip! The diagnostics suggested a potentially defective cable or plug connection. Where exactly should I be looking around the throttle body? Any specific plugs or cables that are prone to issues?

Right, cable or plug. In my case, it was a dodgy connection near the accelerator pedal sensor, which feeds into the cruise control system. Based on your error code, throttle body connections are worth inspecting. Tracing wiring can be a pain. Given the diagnostics, I'd say save yourself the trouble and take it to a workshop. It should be a quick fix, and not too expensive to trace the defective cable.

You were spot on! Took it to the workshop, and it turned out to be a loose connection just as the diagnostic suggested. 95€ later and it's all sorted. Thanks for the advice!
