Partner Electric Cruise Control Failure

Sounds like a potential actuator issue. Have you checked the cable and plug connections to the cruise control system? A defective connection there could easily trigger those symptoms. Do you have access to a diagnostic tool to read the specific error code?

Thanks for the tip! You mentioned an actuator issue, but I'm not entirely sure what you mean. Are there any specific points on the cable or plug connections I should be looking at? And no, I don't have a diagnostic tool myself.

Okay, without the diagnostic tool, it's harder to pinpoint. By 'actuator issue,' I meant a potential problem with the component that physically controls the cruise control. Since you're seeing an error message and have confirmed non-functionality, and given that it's a relatively new vehicle, a faulty cable or plug connection is the most probable cause. Honestly, given the electric engine, it may be best to take it to a workshop.

Thanks for the advice. After checking the connections myself without success, I took it to a shop as you suggested. Turns out it was a defective plug connection as you suspected, repair cost me 95€. Thanks!
