I have a 2000 EB 2x4 and the air suspension has been acting a little strange lately. Whenever the car is sitting parked on a steep driveway, the back end will almost always drop completely. However, when we're on a flat surface, it will only drop part of the time. There are many times where the car will sit overnight and i'll come out in the morning and its fine. Sometimes it will go several days sitting parked just fine. Then there are some days when i'm driving on the highway on a relatively level road and i'll notice it drop or i'll hear the compressor running. I don't think its a leak, otherwise it would be dropping all of the time, right? Every time i fire up the car and close all the doors (even if i'm on a very sloped driveway as mentioned above) the compressor will kick on and the back end seems to level off just fine. So, does anyone have any idea what the problem may be? It is a bad sensor somewhere? Or is it possible that there is a leak even though it isn't consistently low? Or something else? Note that this doesn't drop often. Maybe like 1 out of 10 trips it will do this. I am well aware of the conversion option, however, that isn't something i want to do at this time, especially if its just a bad sensor or something. Any advice?

We may have the same problem. Keep in mind the compressor runs even if the car if off. So your compressor might just be topping off the bags when youre not around

what I did further was, on days that I park and the back is level, I switch off the air suspension. And it keeps it level for days until I decide to drive it and suddenly drops

I agree, with the compressor off, it should not stay up if theres a leak

Not to sure about this awnser but it is worth a shot. The bags have solenoids on top of each bag, it could be that over time they have built up residue on them causing them to "stick" open a little and slowly bleed off.

The other thing that I think it could be is possibly the ride height sensor on it's way out, or gummed up as well.

Hope this helps with a direction to look, and I am with you on not "converting" the system to coil springs.
