Many of the early W220 chassis had air-matic problems. But by chassis number that car is well above the problem area. Also there were several recalls on that car in that first year. Also the rear brake rotors seem to warp quite often.
ALL of the car operates by computer networking, even turning on the dome lamp!! SO diagnostic equiptment will be needed to diagnose almost "ANY" problem.
