Replacement of Air Supply Device (air pump)

[rogerkiu]

Hi all! Recently my car received 'Selflevl Susp. Inact' error message once. I tried to press the up and down button of air suspension and the light just flashed 3 times without action. I used DIS to check the fault code, it says something like 'accumulator ... remains constant...', actually I don't remember the exact words. I cleared the fault code and the car comes back to normal without the fault code. After having cleared the fault code, I also tested the up and down botton and it works normal. Just wonder does this mean my air pump is about to fail or just some kind of computer error (nothing needs to be done on this)?
