Problem Description and Possible Solution
The active body control system can leak fluid from numerous areas, including the tandem pump, hydraulic lines, struts, and/or seals. If it is not repaired, the vehicle ride height could drop too low and cause damage to the undercarriage.

The airmarmatic message light contiues to come on stating stop car too low, don't drive; car is dropping very low with loud noises. The hydraulics drop from left to right. This is ridiculous. $95,000 vehicle and all of the CL's, SL 500's are having This same problem.The is
truly a safety issue.The manufacture is continuing to make the defected Tandem pump and Mercedes is continuing to rip people off and charge $5200! I would not recommend anyone buying a Mercedes and their customer service is very poor.I think everyone that owns a mercedes and having this problem should report it to the Department Highway Administration.
The hydraulic fluid leaked out from under the driver side and the whole car is too low to the ground. what are the possible causes and average cost to repair?
I have a 2003 500SL with the same problem. ABC light is on when I start the car and then goes off while I'm driving. The front left of the car lowers when not being in use. I have replaced every thing on the suspension except the Hydraulic suspension valve. I have spent over $5,000 trying to fix the problem. Now the Mercedes dealer tells me that I need a new Hydraulic suspension valve at a cost of $2600. I have leaks all over my garage floor and I always am filling the ABC reservoir with hydraulic fluid. One mechanic said that I was overfilling the tank and that was causing the leakage. I'm at a loss on what to do and exactly what the problem is.
MY ABC LIGHT CAME THEN MY CAR BEGAN TO DROP TOO LOW
Active body control light in red (drive careful) on the left side I see an oil leak. Afraid to go to dealer as they overcharges for everything. Best to buy the parts your self ad hire a mechanic to do aside job.
purchased with the ABC light on. Had a pump put (because of hyrdolic leak) on and ABC went away for a day and returned. Took car back to Mercedes repair shop and they said that the computer says some framework need to be repaired or replace, costing an additional 2400.00. Any one heard of this before and what was your solution?
Tandem Pump Failing. Fluid Leaks. Power Steering gone and ABC system is out. Car dropping

Abc drive careful light came on , drove car for 10 miles home, woke up the next morning front right side of the car was on the ground , went on forums , everyone said if resevour is empty top off and you should be fine, I toped it off started car and fluid poured out from rear left side
I notice alot of smoke coming out of the rear as i open the hood, uderneath the engine, i notice some hydrolic fluid trapped underneath cover...i replaced the o-ring that was damage and the problem was fixed now it is happening again..i hope there is a recall on this cause it can cause fire and it is not safe to drive...i need afeed back from anyone especially from mercedes benz maker....
DID NOT KNOW THERE WAS A RECALL ON THIS PROBLEM. LOCAL MERCEDES INDEPENDENT REPAIR SHOP REPLACED THE HOSE ASSEMBLY ($118), RE-FILLED SYSTEM ($45 FLUID) AND RECALIBRATED PROPER BODY HEIGHT SETTINGS ($340 TOTAL LABOR)

I replaced the tandem pump last year, the front abc block this year, and now the high pressure line blew.
