Espace Massage Seat Failure

That's a bummer! Those massage seats are supposed to be super comfy. I haven't had that exact issue, but I've seen similar electrical gremlins pop up in luxury cars before. Does the seat heating/cooling still work? If those are on the same circuit, it might help narrow down the problem. Also, have you tried checking the fuses related to the seat functions? A blown fuse could be a simple fix.

Good call on the seat heating/cooling – yes, those are functioning perfectly fine. I should have mentioned that earlier. I did check the main fuse box in the engine compartment, but I didn't see any blown fuses specifically labeled for the seats or massage function. Are there any other fuse locations I should be aware of? Perhaps one hidden somewhere in the cabin?

Okay, since the heating and cooling are working, it does sound like the issue is isolated to the massage function's wiring or the switch itself. I'm not sure about hidden fuse locations on the Espace, but it's possible there's a dedicated fuse or relay near the seat itself. Honestly, at this point, with a specific error code stored, I'd suggest taking it to a workshop. They can properly diagnose the wiring and connectors, and probably fix it for a reasonable price.

Thanks for the advice! I took it to a certified Renault workshop. You were spot on; it turned out to be a faulty connector under the seat. They replaced the connector and re-seated all the related wiring. The total cost came to 95€. Massage function is working flawlessly again. Appreciate the help!
