Mercedes Accumulators was a problem for my sl 500. One may burst or loose compression after a period of time & need to be replaced. What this does is help raise & lower the car. Going over bumps in the road my ABC warning light would come on & my rear end would shift to the right when I'm at about 50 to 60 mph on the freeway, it was very dangerous to drive the car in the rainy conditions because the car would almost want to lose control. Being that I'm a mechanic it wasn't too costly to fix myself, you can get the parts online for around $68 to $250 online if your doing the work yourself. Used or new, I recommend replacing both rear if your car saggs on one side after it has been sitting for about an hour or two. Witch ever side saggs is the side that may need the Accumulator reservoir. Also check for leaks, lines as well. Hope this was helpful.
