Scenic massage seat failure

I have a Renault Scenic too. I recall facing a comparable problem with the massage seat in mine. The issue stemmed from a defective connector under the seat. Have you inspected the cable connections and plugs beneath the seat for any signs of damage or corrosion?

When you say 'defective connector', do you mean the main plug that connects to the seat, or a specific connector related to the massage function itself? Was it visibly damaged, or did you have to test it with a multimeter?

It was indeed the primary connector for the seat. Visual inspection revealed no apparent damage; however, upon closer examination, a technician identified a loose pin within the connector. Given the intricacies of automotive electrical systems, I would advise you to have the seating electrics inspected by qualified personnel.

Thanks so much for your advice! I took it to a local workshop, and you were spot on. It turned out to be a faulty connector under the seat, just as you suspected. They replaced the connector, and the massage function is working perfectly again. The repair cost me 95€, which I think is reasonable. Thanks again for pointing me in the right direction!
