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.

2009 Mercedes-Benz S600 Problems
Engine misfires (rough running) and lack of power are commonly caused by ignition coil pack or ignition module faults. Proper diagnoses should isolate the cause and prevent unnecessary replacement of good parts.
The brakes may begin to squeak at about the 50 percent wear point. This is due to the size and material used for the brake pads and rotors. The brake rotor surfaces become uneven, causing a lip to form at the outer edge. This will generally require replacement of the rotors when the pads are worn (pad life varies depending on driving style and terrain).
As brake fluid becomes dirty over time, it can cause a failure of the anti-lock brake system (ABS) modulator assembly. Our technicians recommend a complete brake system flush every two years to help prevent this issue.
The electrical connector at the automatic transmission may leak fluid into the wiring harness. If not repaired, the oil will migrate through the wiring harness and damage the transmission control module. At that point, a new harness and control module may be necessary to correct this problem.

RepairPal Expert Overview:
During production, on fifty-four Mercedes S-Class models, the front and rear door locks may have been mistakenly interchanged. This means that a rear passenger could open the rear door with a simple pull of the interior door handle, and the front passenger could not open by pulling on the interior handle. This situation could affect the safe exiting of the vehicle in a crash or protection against the accidental opening of the rear door by a child. Dealers will inspect the part numbers on all door locks and replace any that are incorrect. The recall began on March 27, 2009. The Mercedes-Benz recall number is 2009030001.
