Air Suspension ride height

[pieter1]

I also experience problems with the air suspension on my e53 4.8is. My problem is similar to all other posted on this forum (eg, Pump is not kicking in, no power on the suspension relay, error message on display, switch LED is stuck on normal, Pump does work, all fuses works, Control box is suspect, etc). Pump only works on direct link to battery and there is no power at the relay in the back compartment.

After a dealership reset the problem repeats itself after 3 days.

My problem is the following:

If there is a leak on one or more of the air springs (wheels) or pipeline, then the vehicle is supposed to drop to a a point. Where is this point?

The vehicle stays on the same height for the last 3 weeks, with an inactive air suspension. The measured distance from the bottom of the rim to the week arch is between 695-700mm on all four wheels. Is this the lowest it can go and what is the normal height?
