Mistra massage seat failure

Interesting. I own a Mistra as well, and I recall encountering a similar hiccup with the massage seat a while back. Did you check the cable and plug connections beneath the seat? In my case, it turned out to be a slightly dislodged connector. Give it a look; it might just save you a trip to the shop.

Thanks for the tip! When you say 'beneath the seat', are we talking about the main connector block or is there something more specific I should be looking for? Is there any way to get to the plug without disassembling the seat?

Precisely. I am referring to the primary connector block situated underneath the seat. Accessing it might require maneuvering the seat to its highest position and tilting it back slightly to gain better visibility. I would suggest consulting the service manual for detailed diagrams. While inspecting the connector, examine the pins for any signs of corrosion or damage. Ultimately, the error code suggests a defective cable or plug connection of the component, so a visit to the workshop is inevitable to verify this suspicion.

Okay, I appreciate the detailed explanation! I think I will follow your advice and take it to the workshop, as I don't want to break anything while disassembling the seat. It's probably still under warranty anyway. The repair bill was 95€.
