What are colors for pneumatic lines on MCS seats?
I am troubleshooting my multicontour seats (front and rear) on my 2010 S65 as none of them are working. I have the pump and reservoir out. Looking at them there is a series of lines:
Green going from pump to reservoir
Blue going from pump to reservoir
Red going from pump to car
Gray going from reservoir to car
Black going from reservoir to car
Anyone have any detail on what each of these do?
Also does anyone know the working pressure of the system as I don't want to overpressure it while checking for leaks.
