multi contour seats

[stu 123]

hello all my problem is the multi contour seats are not working /inflating. the car is a 2012 e220 cdi cabriolet it might be something as simple as the fuse
as i cant hear the pump working at all
but what i need to know where is the pump located in this vehicle as once i find it i can see whats going on
many thanks

the pipes can crack, the air cushions can leak and where its going for long enough the thermal trip cuts to protect the pump and on mine doesn't reset even with high end diagnostics.... fixed the leak and whilst kneeling on the rear seat checking fuses on the Rear SAM, squashed a cushion just enough a sensor somewhere felt enough pressure for it all to wake up and get over itself

on mine its also normal the control module "ages" and has to be replaced....
on mine the pump is in the boot (where the leaking pipe was)
