Seat Mii Electric Cruise Control Problem

Sounds like a faulty system to me. I had a similar cruise control malfunction on my Mii. Did the diagnostics show anything?

Diagnostics did show an error, yes. Something about a faulty system. Was it the same for you? Where was the issue?

Yep, sounds exactly like my issue. The dealership suspected a problem with the steering wheel controls themselves, or the wiring to it. They checked the connections and found a loose plug. You'll probably have to take it to a workshop.

Thanks! I took it to the shop, and you were right. It was a bad connection in the steering wheel. 95€ later, the cruise control is working. What a relief!
