Air suspension issue. No Faults but rear is sagging. :( PLEASE HELP.
Right now i have a problem the rear is sitting low the front is fine. But there are no codes or errors and no message on the dash. Where should i start? The front bags are new the rear i am not sure about but they look good. But even if they where leaking wouldn't the car try to pump them up still? I have a brand new compressor installed in it. So can't be it. Any help is appreciated. |

Looking through the menus in my scanner I came across the calibrate suspension height. Seems like the right place to start

Sag means leak. Can be in hose or bag or valve. I would spray with dish soap mix and look for bubbles like finding natural gas leak.

I Did that already checked all the bags and hoses the only place i haven't looked at is the valve body under the car... And am wondering if anyone had a problem with the valve body leaking or just not working.

I would suspect a leaky valve. It sounds like a part that could be refurbished. (Dirty valve seat).

In almost 8 years on this forum I've never seen the valve body leak under the car.
Your front bags are new, the rears are original we suspect. Your compressor is new. We suspect the level sensors are original? Read the codes it is throwing in the EHC module as you said the fault is on the dash. Report back to us. I've also seen the module itself go bad, the part # that it was revised to ends in #999 I believe, its not a cheap part. You have 3 items to check out: -Rear bags (however you said after you ran the calibration routine it started sagging in the front and the rear holds air, which makes me think its ok) -Leveling sensors (and the "linkages" that hold them on the control arm, they are $6-7 but are a ball/socket joint that sometimes seize up) - one level sensor in front and one in rear -EHC2 control module (if needing to replace its about $600-700 and needs to be coded) IF the error is on the dash, read the codes and post them.
