Mercedes Air Suspension Warning

The air suspension in your Mercedes model uses air springs instead of traditional coil springs. While air suspension has many advantages, one of the most common problems with this system is air suspension failure.

There are several potential causes of air suspension failure, including leaks in the air springs, compressor failure, and electrical issues. In some cases, air suspension failure can be caused by simply over-inflating the air springs.

Whatever the cause, air suspension failure can be a major problem for Mercedes owners. In addition to making the ride less comfortable, it can also lead to premature wear on the suspension components and decreased fuel efficiency. As a result, it is important to have any suspected air suspension problems checked out by a qualified technician as soon as possible.


There are several reasons why air suspension failure may occur in a Mercedes. One common cause is a leak in the air suspension system. This can be caused by a hole in the air compressor or a loose connection in the air line.

Faulty Parts

Another cause of air suspension failure is a faulty air spring. Air springs can become damaged over time, causing them to lose their ability to support the weight of the vehicle.

Another common cause of air suspension failure is a faulty air suspension strut. Struts can become damaged or worn out over time, causing them to lose their ability to support the vehicle.

Age and Use

Finally, air suspension compressors can fail over time due to wear and tear. If your Mercedes has any of these problems, it is important to have it repaired as soon as possible to avoid further damage.

Common Indications of an Air Suspension Failure

There are a few telltale signs that your Mercedes air suspension has failed.

Common Indications of Mercedes Air Suspension Failure

  • Swaying: One sign is that the car sways more than usual when cornering. This is because air suspension uses air cushions to level the vehicle, and when these cushions fail, the car no longer has this support.
  • Bouncy: Another sign is that the car bounces more than usual when driving over bumps. This is because air suspension provides a smoother ride by absorbing shocks, and without it, the ride is significantly less comfortable.
  • Odd Angle: Air suspension failure can cause the car to sit lower than normal. This happens because air suspension uses air pressure to support the weight of the car, and when this pressure is gone, the car sinks closer to the ground.
  • Unusual Noises: Finally, air suspension failure can cause strange noises when driving. This happens because air suspension uses air compressors to pump air into the air cushions, and when these compressors fail, they can produce a loud banging or humming noise.
