The active body control system can leak fluid from numerous areas, including the tandem pump, hydraulic lines, struts, and/or seals. If it is not repaired, the vehicle ride height could drop too low and cause damage to the undercarriage.

    I had a power steering fluid seal go bad and the garage that worked on it put power steering fluid in the ABC fluid housing which made the ABC system suck up the power sterring fluid and it caused the whole ABC system to go bad. mercedes fixed it, but it was $3000 to flush the system and buy a new pump.

    starting to notice regular ABC visit workshop messages. I keep my eyes on the Hydraulic fluid levels to ensure that the system doesn't run dry. Now car won't raise or lower, also noticing continuous drip underneath the car. Seems to be occuring in the front, near pulley but can't tell due to the frame. I can see fluid dripping from the bottom of what looks like the tandem pump, but could be coming from a high pressure hose connected to it, can't tell. Starting to prepare for a huge repair bill.

    out of no where, fluid was pouring out under the car and after i popped the hood, saw all this fluid spitting out of the ABC housing/cap area. I'm scared of what this is going to cost. Had no warning or issues with the suspension prior.
