where is the ADS fluid and how to bleed it
 

I am rebuilding a 1994 SL500, I removed the ADS valve block to remove and replace the coils, Now I can not figure out where the new fluid goes and how to bleed the system. Can anyone help?

Thanks ED

There are some owners manuals on line, info should be in there.

I "think" the power steering pump has a 2nd section for the ADS and may share fluid. Look at the PS pump, a pressure and return line will go the the steering gear. If there are two more lines at the PS pump, that would be the ADS.

Yes, it is in the power steering pump. There is a filter there also. Be sure you use only MB hydraulic fluid, Been there done that on two different CL's

On the leveling valve in the front there is a 5mm (maybe 4) allen setscrew with a locking nut on it on the rear side. Engine running loosen that setscrew just a smidge to bleed the valve. I don't recall if the rear valve needs to be bled after the front, its been a long time. If it doesn't come up in the rear the rear level valve has a bleeder nipple similar to a brake caliper, engine running of course.

Thanks for the help. I will try it tonight after work, I am picking up a new filter at the dealer also.
