Report: Active Body Control System Can Leak Hydraulic Fluid
Mercedes-Benz CL600 Problem
Average Mileage: 70,222 mi (28,000 mi - 140,000 mi)
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.
My ABC lights are on and it says that the car is too low to drive. Had it repaired and two weeks later the same thing happen to my 2000 S 430.

The dual power steering/active suspension pump is leaking. To avoid the system going out I am replacing the pump, flushing the system etc. cost $3000+. It's a pain way to expensive etc but the car is a dream in performance,m comfort, looks etc. It is after all a very expensive car so repairs will be expensive. To bad a car this expensive and good can't also be reliable.

I had a similar issue on my 2004 CL 600- V12. Both the Red and white ABC light dispalyed in the instrument cluster. I had to replace the dual stage hydrauic pump. Found an OEM on ebay for $800. Mercedes dealer quorted me $2000. I had the dealer repalce and install. Total cost to repair was $2000.

Leaking hydraulic fluid from the suspension reservoir. May install solid metal struts instead.
Also warn suspension bushings. Have to purchase the whole part, not just the bushings,
(crappy German engineering) Most unreliable car I have ever owned!
hydrolic fluid leaks sometimes. Causing system to go haywire while driving down the road. Called MBUSA and they didn't care.

multiple times over life of car even when under 40K miles; very expensive each time and very unreliable

For some reason the car decided to lose pressure and the ABC system is going out. The dealership says that it is the purge valve and is going to cost $600 to fix. This is an extreme set back in the overall quality of this car.
