Hi Dave,
I have a '93 300SL which also has the hydraulic  suspension.  I have had no proble with it yet but I understand the solutions  can be quite pricey.

  Hi Jan,
  I also have the factory R129 dvd which in an earlier post I offered copies to anyone who has experienced ADS (adaptive Damping System) problems. I would extend that offer to those that have had experience with the hydraulic self leveling suspension, as that may be the culprit. It is a complicated system, that is difficult to troubleshoot. The dvd does have quite a lot on it, but I have not been able to fix it yet. The dealers solution is to keep replacing parts until it works. 

  This system is standard on the SL600, but my understanding is that was also available on the Sl500. I have replaced the accumulators and there are no leaks, everything seems to work, but there is a loud hydraulic "squealing" noise when I start it up that sounds like the system is pressurizing. After a short while it changes in intensity and pitch and goes away. sometimes I hear it doing this while driving. Is this normal? Any experiences would be very much appreciated.

  As someone who has bought a number of workshop cd's off eBay, I would also add a word of caution....most are useless. I also have the original factory W124 cd's (2) which are also very good. But the rest were a waste of money.
