N300 Multifunction Steering Wheel Failure

A non-functional multifunction steering wheel and a stored error is concerning. I've seen similar things caused by different issues. A defective cable connection inside the steering wheel could be the problem. Have you done any recent work on the steering column or electrical?

Thanks! No recent work has been done on the steering column or electrical system. If it could be a defective cable, what diagnostic steps would you recommend before I take it to a professional? Is there a tool or method to check the cable connections?

Since it happened suddenly and no work has been done, I wouldn't recommend trying to diagnose it yourself, especially with the steering system. You could damage the airbag or steering controls. Take it to a workshop for inspection. The error code should help them find the problem. A faulty cable connection is likely, and I'd expect a repair to cost around 95€.

Thanks for the advice! I made an appointment with a workshop. It was a defective cable connection in the steering wheel, and the repair was exactly 95€, like you said. Thanks again!
