Air Suspension Control Unit Fail?

Tewie · 11-03-2018, 03:46 PM

When left overnight, my 2008 E70 sags in three corners - both rear and the driver side front corners. I do not suspect all 3 air bags failed at the same time, however I will perform a leak check for peace of mind. I want to know if anyone has had a problem with the Control Unit for the air suspension and if there is a way to test the unit. My objective is to avoid throwing miscellaneous parts at this since they are not very cheap. Thanks.

Sounds like air compressor. Check the recent thread about it here if you run a search.
