ABC suspension reservoir pressure shot fluid out the top
Has this happened to any one?
I wasn't the person driving the 2002 S55 at the time but when I got it back I noticed the res empty with the suspension dip stick popped out and a nice spray pattern under the hood. I hooked up the star and ran the series of tests: sensors, valves, pump, dynamic test. Every thing passed with out any new codes or leaks. I'm not sure where to go from here, what would cause alot of pressure in the suspension fluid res?

that sounds plausible. will a bad sphere throw a suspension code? what are the symptoms of a bad sphere?

Will happen if either of the suspension leveling valves don't fully close.
Fluid flush & rodeo for 30 minutes, and of course a new filter in the reservoir.
