The BMW 5 series models are famous for their comfort despite more than twenty years passing since the release of the first models. Even now, well-known manufacturers (Mercedes-Benz, Audi, Bentley) are using technologies similar to those introduced in the BMW 5 Series.
Features of the Suspension of BMW E39 and Issues Related to the Operation
The E39 model received a new air suspension, which significantly increased the ride comfort. Such solutions had previously been used only in cargo vehicles. Most of the components of the front suspension were made of aluminum, which meant that the system had to be maintained with the utmost care:
- The electrolyte must not get in contact the parts.
- Only a stainless-steel brush can be used for cleaning.
- During repair works, sparks must not fall on details made of aluminum;
- The elements must not be heated over 80 degrees.
The rear air suspension has a simpler design. However, it is also prone to some malfunctions. The manufacturer claims that air springs can provide comfort for 100 000 km. But in reality, this figure is overstated. Even on high-quality German highways, air springs don’t last that long.
The air suspension compressor is a fairly reliable component. But when the air tightness of the air springs is compromised, it has to work to its limits. The compressor valve is the first part to fail due to that overload.
Even an inexperienced owner of E39 will be able to determine the wear of one or several elements of the air suspension First comes the loss of comfort. The car cannot cope with road bumps any more. There are also unusual sounds, squeaks, and knocks. Sometimes, this can happen on a perfectly even road.
Do not ignore any suspension malfunctions. They cause not only loss of comfort for the driver and passengers, but also pose a threat to safety. Over time, the vehicle responds ever slower to the driver’s inputs, which can ultimately lead to an accident.
