The SLS engine driven pump can leak both. Slsmanual03. Self leveling suspension bit of quick info. How it works. Self-levelling suspension --- wiki. Purpose[edit] There is an inherent conflict in suspension design - if the springs are soft, the car will be comfortable but dramatically affected by load. If the springs are hard, the car will be uncomfortable, but less affected by load. Numerous manufacturers realize this conflict and have pursued different avenues to achieve both comfort and load capacity simultaneously. History[edit] In 1954, Citroën introduced the first self-levelling rear suspension, and then in 1955 pioneered self-levelling of all four wheels, using its hydropneumatic system. Since then, millions of Citroën cars have been equipped with self-levelling as an unobtrusive, but integral design feature.
The Citroën's dashboard includes a five-position lever which allows the driver to select whether the car would travel with the body in a high or low position. In 1966, Rolls-Royce licensed Citroën's hydropneumatic system to fit to the rear axle of the Silver Shadow. Brief explaination on self leveling suspention.
Keep on the level even when you're towing a heavy load: Self-levelling suspension adjusts the height of your vehicle's rear axle for better driving dynamics and safety. Carrying heavy luggage or towing a trailer can cause a vehicle's tail to sink downwards. BMW's self-levelling suspension system counteracts with problematic tendency by inflating pneumatic cylinders integrated in the rear axle assembly that lift the chassis higher. Pneumatic pressure is maintained by auxiliary compressors which are electrically operated. The compressors run independently of the engine and can be adjusted individually if required - for example, when carrying an uneven load.Maintaining a steady chassis level is essential to your BMW's dynamic handling.
Towing or transporting heavy loads can lead to uneven tyre wear. Furthermore, oncoming drivers can be blinded by the upwardly-tilted headlight beam. Self leveling suspension. Diagram. Diagnosing and Repairing Hydraulic Self Leveling Suspension (SLS ) | Suspension Problem | MercedesSource.com. Come on people, I know many consider this an annoying and expensive system to maintain, but if one neglects it, it is just going to get worse (and more expensive)!
The SLS system is an amazing piece of engineering and when working properly, it can give amazing performance for a heavily loaded station wagon - and we all know they tend to get overloaded! If you feel you have to have a 300TD wagon and do not want to repair or maintain the SLS, then I would recommend you sell it and get a sedan instead. It is possible to remove the hydraulic suspension and replace it with regular springs and standard shock absorbers. Granted it is a cheap alternative the a full overhaul of the SLS system, but most who have tried this have not been happy with the conversion over the long haul. Why does one own a wagon in the first place - to haul large or heavy loads ?? The SLS engine driven pump can leak both internally and externally. What can fail on self leveling suspension system?
