Seat Ibiza cruise control problem

I had a similar issue with my Seat Ibiza some time ago. Cruise control suddenly became non-functional, and the speedometer displayed an error message. Did you perform any diagnostics? Have you checked the throttle body?

You mention the throttle body. Was the error message you received the same? Did a diagnostic tool specifically point to the throttle body connection, or was it more general?

Yes, the error message was identical, and after running diagnostics, it indicated a faulty system related to the throttle body. Given the stored error memory points towards a defective connection, it is likely the same problem. My recommendation would be to visit a workshop to confirm, but it sounds very familiar.

Thank you for confirming my suspicions. I took it to a workshop, and indeed, the diagnostics pointed to a faulty connection within the throttle body system, precisely as you suggested. The repair, including parts and labor, amounted to 95€. Cruise control is now fully functional again.
