2000-2006 Mercedes-Benz S600 V12 Model 4-Wheel Hydraulic Suspension Conversion Kit (MZ14F)

Replaced Components
The 2000-2006 Mercedes S600 V12 Model is built with the following suspension components: 2000-2006 Mercedes S600 V12 Model Hydraulic/Air Springs (x4)- (models with air suspension only). Commonly referred to as air bags, a plastic and rubber bag that is fitted on top of the strut that uses pressurized air as a cushion instead of a metal coil spring to hold a vehicle off of the ground and off of its wheels. These are the number one cause of all air suspension leaks. All air springs all go bad at about the same rate. If one is leaking, the others will not be far behind. For a proper repair, all of them need to be replaced at the same time. If your model has hydraulic springs/struts, then it is filled with hydraulic fluid instead of air to adjust the height and dampening of the vehicle. 2000-2006 Mercedes S600 V12 Model Hydraulic Reservoirs (x4)- (models with hydraulic active suspension). If your model of Mercedes-Benz has this, then the steering pump also pushes hydraulic fluid to your 2000-2006 Mercedes S600 V12 Model Struts (x4)- a type of shock absorber; has metal tubing filled with gas-charged hydraulic fluid that is connected to the wheel of a vehicle in order to reduce the effects of vertical travel on a rough surface which controls the bounciness, and therefore comfort, of a vehicle.; the air spring assembled on top of the strut is commonly referred to as an air strut. 2000-2006 Mercedes S600 V12 Model Height Sensors (x4)- a linkage located near each wheel of a vehicle with any electronic suspension that, either mechanically or electronically, constantly measures the height of the vehicle, and reports this information back to the control module so that the computer can identify if changes in height need to be adjusted accordingly. The ride height sensor is a moving part, and like all moving parts, they will eventually wear out. 2000-2006 Mercedes S600 V12 Model Air/Hydraulic Lines- tubes that run from a compressor to the air struts (or a hydraulic pump to the hydraulic struts for models with hydraulic active suspension), which carry pressurized air to the air bags (or hydraulic fluid to hydraulic struts) in order to adjust the height of the vehicle, respectively. 2000-2006 Mercedes S600 V12 Model Solenoids (x4)- usually L-shaped, these plastic components connect the electrical connection and lines of suspension components to the suspension control module on vehicles with active suspension. The solenoid regulates the air pressure for each air spring. Solenoids start to leak as they wear out causing the vehicle to sag or to lean. This will cause the ride height sensor to send a signal to activate the compressor in an attempt to inflate the air suspension and level out the vehicle. This excessive work load will eventually lead to total failure of the compressor. 2000-2006 Mercedes S600 V12 Model Compressor Assembly- (models with air suspension only). Creates/sends pressurized to active suspension components. When the air suspension starts leaking, the compressor/pump starts working harder to try to keep the system inflated. By the time air suspension leaks down completely, sitting the vehicle on its tires, the compressor will either have failed or be well on its way to full failure. Buying replacement struts and taking the time to install them only to find out the compressor still needs to be replaced can be very frustrating, time-consuming, and expensive. 2000-2006 Mercedes S600 V12 Model Hydraulic Pump- if your Mercedes has hydraulic suspension instead of air suspension, then the hydraulic steering pump will also serve as the reservoir for the hydraulic fluid going into the struts. 2000-2006 Mercedes S600 V12 Model Suspension Control Module- a computer which is responsible for the operations of the air suspension system and maintaining the vehicles correct ride height. 2000-2006 Mercedes S600 V12 Model O-rings- Although they are the least expensive parts of the air suspension, they are responsible for maintaining the seal where all of the air lines connect. Be sure to replace the O-rings when repairing any air suspension system.

Suspension Failure Signs
Look for these classic indicators that the air suspension system is going bad in the 2000-2006 Mercedes S600 V12 Model. An inability of the S600 to reach and maintain its proper ride height is one major red flag. A height variance between different sides of the vehicle is also a symptom of a failed suspension (this may look like one sagging end or a shifting lean from side to side). Height imbalances, if not fixed promptly, will wear out the air compressor. Once the air compressor has stopped working, a suspension warning light will illuminate on the dashboard. At this late stage, any repair or replacement will be costly. The S600 owner should detect suspension failure early to avoid this worst-case scenario.

OEM Replacement Cost
'+ Air/Hydraulic Strut Assemblies ($2,000/strut) ) + Air Compressor Assembly ($380) Or + Hydraulic Pump ($1,300) + Hydraulic Reservoir ($40) = TOTAL: Over $9,000 (and that doesnt even include replacing electronic components that are known to fail such as the height sensors).
