Where are the springs on a Mercedes Benz Airmatic?
The rear springs on some AIRMATIC suspensions can be labor-intensive to replace, while others are as easy as replacing a strut. The 2003-’09 E-Class (W211) is known for leaking rear springs. These springs mount to the lower control arm and the sub-frame.
What are the problems with Mercedes Benz Airmatic suspensions?
There are three main problem areas for AIRMATIC suspensions: relays, compressors and leaking airbags. If a problematic AIRMATIC suspension comes into your shop (one that is dead or intermittently leaving the vehicle on the bump stops), one of the first things to check is the high-amperage fuse for the compressor.
Where are the sensors on a Mercedes Airmatic?
The two front level sensors are located at the air suspension struts. In some models, you will only find one sensor at the rear axle. In this case, it measures the position of the torsion bar which provides an average vehicle height for both rear wheels. Mercedes – suspension – airmatic – strut
When did the Mercedes Benz Airmatic system come out?
The system employs electronically controlled air springs that provide an ideal balance of ride comfort and handling. The Mercedes-Benz AIRMATIC suspension system was introduced in 1999 on the S-Class and has subsequently been used on the E-Class and most of the automaker’s SUVs.
Air can potentially leak back into the compressor and cause internal damage to the compressor itself. This will impede the quality of journey and also the suspension elevation of the vehicle.
What does the air strut do on a Mercedes Benz?
The air strut is an assembly consisting of a monotube shock absorber with electromagnetic damping valves that change setting based on commands from the suspension control module. An air spring assembly sits on top of the strut and is responsible for height adjustment as well as air spring damping.
What causes Airmatic struts to get stuck up?
Unfortunately, the most likely cause is fairly expensive – the airmatic struts are expected service items. That is, they don’t last forever. The failure is usually a split in the fabric and rubber diaphragm inside the strut. It is possible to replace the diaphragm, but that job beyond the capabilities of virtually all owners and almost all shops.
How does the Mercedes Benz Airmatic system work?
This system replaced the traditional coil-springs found on cars leading up to this time with air-springs with electronic level control and adaptive damping at all four corners. The combination of adaptive damping that adjusts based on road quality and driving style in concert with air springs makes for an extremely comfortable ride.
Why is my Mercedes E Class rear suspension leaking?
There is also another possibility that the air pipe going the the o/s/r air cushion is leaking slightly at any of the joins. A common place is under the rear seat base on the n/s/r where you’ll find the air pipe from the front passing under the rear seat & there’s a connector joint here which is taped up in felt tape.
Why is my Mercedes 211 rear suspension not working?
The pipe pulls apart allowing air to escape which in turn causes air loss to the rear air cushions causing ride height problems.
