You'll need to use a Active Body Control Conversion kit made especially for your car. The LAST thing you want to do, is to throw junkyard parts on it and have the hydraulic system "dead-head" and burst somewhere.

These mega-expensive ABC repairs are nightmares! I've seen repair bills get as high as $22k! Do yourself a HUGE favor and get away from the ABC forever with a Active Body Control Conversion

You could have any number of problems. The 2 things you can easily do are make sure the trunk partition panel is in place to allow top operation and make sure you have at least 12 volts at your battery(starting the cat should take care of that). Beyond that you really need diagnostic equipment that can communicate with the top control unit to figure out why the top isn't working. Possible causes are low fluid level due to a leak in the system, failed position switch or broken wire between switch and control unit, or a failed pump, among others.

PERHAPS A FUSE UNDER HOOD OR IN TRUNK. COULD BE A BODY CONTROL MODULE

your problem is the fluid is low and doesn't have enough fluid in the pump to operate. you can add fluid at the rear underneath your spare tire. the fluid is a special blend only at mercedes benz dealer. anything else will cause the top cylinders to fail and it is very costly to repair. the fluid is about $20. It leaks because you have a leaking seal in the top cylinder. Mercedes knew this would happen this is why it leaks right in front of your face hard to ignore that huh.
