A great full hydraulic system experiance to share - PeachParts Mercedes-Benz Forum

I have a 560SEL 1989 car that have a full hydraulic system (front & rear self leveling suspensions). The problem started when sometimes the car squats from both front and rear sides. I asked almost everybody here but no one gave me the solution. I said it is fine, I can live with it. Then the problem got worse that some times in traffic the suspensions light lit, but after speeding for a while it gets off. I tried to open a little valve designed to release the air from the hydraulic oil and it helped for a while. Now to the worst part of the story, the car started bouncing on any little height on the road. And because my wife is pregnant I became so upset about the car and thought of repealing that hydraulic system (that I love) and get back to normal. But someone wrote here in this excellent forum that the car bouncing is most likely to be caused by the accumulators (we call them here balls). I asked my mechanic to replace the bad accumulators but he told me that placing them on a full hydraulic system is too risky and the car may never rise up again. I believe him because I hared that from more than one mechanic. I told him to test or replace one by one and when one is tested or replaced he must turn on the engine for a while. And FINALLY YESSSSSSSSSS it worked. Thanks god that my hydraulic nightmare is over as well as the ASR one. By the way I don't know how the ASR problem that I mentioned before fixed, it's just fixed by itself

I'd like to thank everyone in this forum for either helping or sharing his/her experience : ))..

I forgot to mention that I ended by replacing the two front accumulators and one rear accumulator.
