Tacuma multifunction steering wheel failure

Hey, that sounds familiar! I had a similar issue with my old Opel Astra, although the symptoms were slightly different. The steering controls went haywire, and the error codes pointed to a control module problem. Have you checked the connections to the steering wheel control module? Maybe that's something to look at before assuming the cable is the issue.

Thanks for the tip! Where exactly is the steering wheel control module located? And how involved is checking the connections?

On my Astra, it was behind the steering wheel, but I'm not sure about the Tacuma. Checking involved removing some trim and unplugging/replugging the connectors to ensure a good connection. Honestly, I ended up taking it to a workshop because I wasn't comfortable messing with the airbag. They diagnosed a faulty connection and fixed it pretty quickly.

Thanks, I appreciate the advice! I took it to a local shop and you were right! Turns out it was indeed a defective cable connection in the steering wheel, and the repair cost 95€. All working fine now!
