550 coupe command not adj seat
2015 S550 coupe, the command center that enables the dynamic driver seat as well as massage, etc. is changing on the display but the seat is not moving. Hoping maybe it's a fuse?

It could be a fuse, but it's more likely the seat module itself. Those modules are a known weak point. First, check fuse F34 in the rear seat fuse box. If it's good, the issue is almost certainly the seat control module. It's under the seat. They commonly fail from moisture or just age. You'll need a specialist to diagnose and replace it.

Function disabled as leak was detected, diagnostics needed to re enable pump and locate leak.

I don't know if a Bluescanner will pick it up and reset it.
I use a icarsoft MB v2.0 scanner, and it picked up the air leak and shut down air compressor system.
I then bought a smoke machine off of Amazon and disassembled the trunk (covers and removed subwoofer) on the drivers side to get to the air pump,
and started smoking the lines until I found that the leak was drivers seat (I have chauffer's package and rear executive seats, so they massage too),
Once I replaced the line, I reset the system and all is working now.
