Round seat controls
Hi Everyone,
I have an E250 CDi 2015 facelift saloon and I have seat controls on each door with memory function. Also, on the seat I have a four directional control switch and I am thinking it could be a power issue, broken wire(s) or the switch itself. Would anybody happen to have a wiring diagram, or a procedure of how to remove the control switch? Any help would be appreciated.
Kind regards,
Steve.

-- The heavy duty power actuators are under each seat
-- The door modules host the buttons with loose pins in charge of chaos.
In between these modules is the body CAN-Bus network-B.
Connect your MB scanner for troubleshooting functions and read active faults.
Repair likely to be in the door based on scanner results.

Missing Information
Hi,
I think i was getting carried away with the fault i have and i did not explain my problem properly.
I have seat door controls with memory function for both front doors and they work perfectly.
All the seat motors also work perfectly.
My issue is that the buttons on the seat itself, do not work. My diagnostic scanner does not report an issue. Therefore, I am thinking it is the switch on the seat itself, and I need to know how to remove it so I can test or replace it. I will investigate further when I get chance.

This function may not be CAN enabled for scanner to interact with it... usually blader fails.
