Air suspension question is for a BMW e39 528i touring 1998

In the boot or side panels. Only has rear airbags

If the car is riding lower than usual, making abnormal sounds, and its compressor won't start, it indicates the replacement of air suspension compressor.Accordingly, if the compressor has failed, there is usually an air leak somewhere in the air ride suspension that needs to be found and fixed before a new compressor is installed.

The air compressor is what provides the air suspension system with compressed air required for it to function. If you suspect that there is a problem, you should have proper vehicle suspension inspection by a professional technicians such as Eurobahn BMW MINI Mercedes-Benz Audi. They can determine if the vehicle needs an air suspension compressor replacement or repair.

whats the problem there are relief valves for air shocks and the shocks may be blowen out
need better detail

clear the OBD codes that should turn off warning light

yes you can replace air susp with others, also instal coil springs

The compressor is next to the air box on the driver side under a plastic cover. One plug, two hoses and 3 bolts that hold it down. The hose on the top of the compressor is a quick release. Push in hose and hold red ring at bottom, and it should pull right out

Check for pressure out of the air pump. If there, then the problem is a blown seal in the shock.

Hi,

Your concern is your BMW displays the message "SELFLEVEL SUSP. INACT" which indicates that the car's computer detects a problem with your active suspension system. Self-leveling is standard to most late model BMWs. It works on a pump, an air system and a computer that tells which suspension gets how much height, ride stiffness and other suspension settings.

Your concern is a known issue though not that fairly common. Technically, the best would be to contact your dealer or if in The USA, BMW of North America, LLC. call (800) 831-1117 or email [email protected].

You may want to mention a possible problem with the firmware/software of the EHC (Electronic Height Control) Control Module. They may want to recode (flash). It is also possible to have air leaks in the system specially on the suspension bladder.

Other things you can check are tire pressure (30PSI), see if your ride is a bit stiff/hard now compared to before the earning displayed showed up, handling difficulty, loopsided/tilted level among others.

Incidentally, if there is nothing out of the ordinary in how the car ride, handle or drive, it may just be a systems glitch. Try jockeying the key to ON/OFF a couple of times.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.
