Average Mileage: 82,976 mi (22,000 mi - 170,000 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.

    I was informed that the hydrulic pump is going out and needs to be replaced at a cost of $1610.00 for parts and $845.00 for labor and also the rear right strut is bad and also needs to be replaced at a cost of $1310.00 parts and $560.00 labor ...among a few other things that would total about $5500.00 to repair everything....i'm in such a dilemma of what to do....i LOVE my car but i'm really hesitate to put that kinda money into it thinking that lots of other very costly things may be getting ready to go wrong with it...i've heard that stuff tends to start breaking at about 100k miles ....anyone have any suggestions or insight or personal experience with any of this???? i would GFREATLY APPRECIATE ANY INFO!!!!

    my '03 sl500 is LOPSIDED!! in order to get into my garage and drive in the city, i need to have my car at the highest lift level and I've had nothing but problems with the ABS system since I bought my car...course MB made this fix and that fix while it was under warranty but the problems persisted. Now, everytime I leave my car for longer than an hour, the left side of it drops...fortunately, when I get in and push the lift button (technically turning it off) the car rights itself, then I just press the button down twice and the car lifts itself again...but this just CAN'T be normal...HELP

    My red light comes and says my car is too low. Previously I had a system fault code of c1525 systme pressure too low,I replaced the ABC filer in expansion reservoiw which csot about $2,134 to service.The dealer recommend to replace bot hthe front and rear valve blocks due to lates fault codes c1525-001-0002-004. This will cost $5,000. Right now I just press the button by my gear shift that lifts my car and it makes the red light go out. I have to do this about four times a week.

    I get the ABC warning signal when I start the car on cold days. Now the dealer tells me I need to replace the fluid & filters at a cost of $800. does this sound reasonable ?

    The answer to save you loads of money is to get rid of the ABC system altogether and replace it with "normal" struts. Its a cost of about $1795 but there will NEVER be another problem with that nasty and costly repair! Go to http://www.youtube.com/watch?feature...&v=SpDdOG--hEQ. This fixes the complete system and no more lousy 1000 rpm whine which is inherent with all SL500 2003 forward! The permanent fix is in and you won't have to deal with hydraulic messes again!
