Fiesta Massage Seat Switch Issue

I had a similar problem with my BMW 5 series a while back. Same symptoms – massage function dead, error code. Have you checked the wiring loom under the seat? Sometimes they can get damaged or a connector can come loose.

You're talking about the main wiring harness going to the seat, right? Was it obvious when you found the problem on your BMW? I'm not exactly an expert, so I'm a bit worried about messing something up.

Yes, the main harness. On the BMW, it was a partially disconnected connector. However, considering you have an error code pointing to a cable or plug issue, a workshop visit might be the most sensible option in your case.

Thanks for the advice. I took it to a shop, and you were spot on. It was indeed a loose connection, just like you said. They re-seated the connector, cleared the code, and all is well. Cost me 95€, not too bad. Appreciate the help!
