Hi,

When you say inact, do you mean the system is inactive? Also, is it both front and rear that are affected? Do you hear the pump running? Do you have single axle or dual axle air suspension?

I attached a pic which shows two fuses and fuse numbers. Check them to make sure they are good and not blown.

Here are a few links you may find helpful when checking:

Let me know.

More than likely you have a blown fuse causing the system to be disabled or a leak in the system. Does the front level off at all or is it all the way down on both sides or just one?

I attached a TSB from BMW but it is not majorly helpful but I wanted to get it to you anyway.

Let me know if all fuses are okay and if one or both sides are down? Thanks
