Defect in accelerator and electronic attachments, part no220 300 00 04. When part failed, initially, car only powered to low speed under load. Had to drive it out of desert and over mountain at low speed, but down hill ok. Eventually parked it off road. When next starting it, it revved to 3500 rpm and held.
Message in display airmatic visit workshop. Diagnosed automatic strut leak. Replaced strut assembly left rear & valve block suspension valve. I still hear air leaking. I've replaces all four air struts over the years. The struts are not cheap. In my opinion mercedes mfg should reimburse me total cost for all four.
On 11/18/16 I was driving my 2000 s430 when wile accelerating to merge onto the freeway my transmission slipped causing my engine to rev. I released the gas pedal & tried to press it again to re engage the transmission but it didn't work. I pulled to the side of the road, placed the car in park, then back to drive.

While driving [address] my car all of a sudden flashed a red warning saying "stop car " warning " do not drive car to low" the car started dropping to the road rubbing tires. I immediately had to cut traffic and pull to the right to get out the way of moving vehicles. This is an extremely scary tragic and hazard!
The whole car was laying on the floor and. The red light flashed on the dashboard that said "stop car too low , because of how low it was the tires were rubbing on the fender and caused the tires to ball up ,I.
Dash lights go out losing speedometer and all instrument aids such as lights high & low, turning signals, and air bag just to mention a few. The dash panel cluster controls so many functions that control of the vehicle becomes dangerous especially at night.
While the contact was driving approximately 35 mph with the air conditioner activated, he smelled a plastic burning odor then suddenly the air conditioned failed to operate. The vehicle was maneuvered to the side of the road, where the contact noticed that faulty blower motor regulator wires melted.
