Seeing as the inclement weather season is fast approaching I'm considering doing my own preventive maintenance on my 2005 SL600 with 41k miles on it. One area I'm considering is the ABC system. I changed the fluid out about 4k miles ago. The only issue right now is every month or so I MAY get a low body height message. It is easily corrected by raising then lowering the body via the button. No leaks.

So, as part of preventive maintenance I'm considering swapping out the 3 accumulators, replacing the seals on the front/rear hydraulic value blocks, then flushing the ABC fuild again.

Worth doing? Best source for parts? I plan on doing it myself (I have access to STAR). What say you well of knowledge?

say i hi from me to your frend, 2002 til 2005 is the ones worst affected, is the age of rubber, and nothing that take care of it , And all will have issues ,every one of them .

is allready slack O ring in his system, i did not say open it. it need licqseal to expand the O ring and all seals in system, so you can expand life atleast 5 more years, me and frends ,pluss many others have now fixed this, .one 2004 with 100 k miles aprox ,was sitting 2 hours before it sank down, Now not moving at all.

he can ofcourse take the job open actuators and change O rings , but still would need this stuff to refresh rubber in shocks and other seals in system. NO need to invent the wheel again, we others done this ,and know what he need do .

I changed the accumulators (SL600 year 06) because I heard slight slapping noises when driving over a manhole cover. The car moved very easily on fast corners and manhole covers. After the replacement, that was over. The parts are 15 years old, it doesn't matter how many miles the car has driven.
