E39 Touring Air Suspension Help Needed
Replaced the prone airsprings on the wifes 530i touring as the car eventually gave up the ghost and looked like a low rider after leaving it for about 3 or 4 hours after driving. However i was dissapointed to find that after the same time duration the car sagged again, obviously not the air springs then £300 later Anyone have any ideas of probable cause before i waste any more money?
Thanks

I don't know anything about BMW-specific air suspension, so take my suggestion with a large grain of salt. I did have a mid-90s Lincoln with air suspension, and the control unit (that regulates pressure in each air spring) built up some rust and started to malfunction. We had already checked all springs and lines for leaks and couldn't find any, and it turns out that the culprit was the regulator. Perhaps this can be tested using the diagnostics of the car's on-board computer?
Good luck.
