Astra Cruise Control Failure

I had a similar issue with my Volvo a while back. Different brand, but the symptoms sound familiar. Was the throttle body checked during the diagnosis? A faulty system in that area can sometimes cause issues with the cruise control. Have you considered that?

Throttle body, you say? I hadn't thought of that specifically. What kind of symptoms did your Volvo exhibit when the throttle body was acting up?

In my case, the Volvo had intermittent acceleration problems along with the cruise control failing. Considering the similarities, I recommend a thorough check of all car electronics by a workshop. It might be a deeper issue than just a simple connection.

Thanks for the insight! It was indeed a defective cable. Cost me 95€ to get it sorted.
