Peugeot 107 Cruise Control Failure

Sounds familiar! I had a similar cruise control issue with my old Renault Megane. The error message and complete lack of function were exactly the same. In my case, it turned out to be a dodgy connection. Have you checked the wiring and connectors to the actuator, or maybe the throttle body?

Thanks for the quick response! When you say 'dodgy connection', where exactly should I be looking? I'm not super experienced with car electrics, but I can usually manage basic stuff if I know where to poke around. Which connector was the culprit on your Megane?

On the Megane, it was the multi-plug going into the cruise control actuator itself. However, tracing it back, the issue was corrosion in the loom where it ran near the engine. Give the connectors a wiggle, and if that does nothing, you might need to get someone to do a proper diagnostics check. It cost me 95€ to fix (defective component connection cable/plug).

Thanks a lot for the advice! I'll check the connections to the actuator and the throttle body first. If that doesn't solve it, I guess a trip to the workshop is in order. At least I have a better idea of what to tell them to look for now!
