Good discussion: https://mbworld.org/forums/e-class-w211/918482-self-leveling-rear-suspension.html
* Eg: Control unit is under the passenger footwell (the carpet up, remove nuts to pull the steel plate). Check this: https://mbworld.org/forums/e-class-w...ml#post8748801 Only relay is for the pump, it's in the engine bay, fuse box on the drivers side corner. Fuse #45 is for the control unit, diagram for fuses is here: https://fuse-box.info/mercedes-benz/..._box_diagram-3
* Checked Voltage on rear level sensor and it goes from 2.8 to 4.9 and it’s on 4.9 when it’s dropped, using a jack.
