SOLVED Air Suspension Finally Got Me
Well, looks like I get to join what looks to be a rather frustrated club. Went outside after the X has been sitting for a week and the passenger front was lower than the lowest setting. Easily visibly noticeable. After a few seconds of hitting the unlock button on the FOB the truck aired up to proper height so it looks like a leak somewhere dealing with the right front. I'm guessing that includes: right front airbag, front axle distribution valve/tank under the truck, and the fittings/lines associated with those. Will get a soapy water bottle ready when able to get it into the garage again. Been remodeling our master bath so I have the tub, vanity, and other accoutrements residing in Red's usual resting place.

Good luck. I just got bit as well. Front drivers deflated after 2 weeks on vacation. Went back up as soon as I unlocked it though. But I’m going in same direction as you.

Triple checking: do you guys have tpms light chronically on? Asking because it happened to me, new air strut constantly deflated and SLS inactive stayed on for almost 3 months. Got solved after overinflated the culprit tire to 50#.
In any case air strut replacement is an easy job. Changed both fronts in the last year. No coding involved

Most likely bag less distribution block. In all my air suspension issues with BMW and Mercedes never had a line issue. Soapy water tells you nothing. if the bags are old start their

My bags are Arnotts. 2 years old. No issues or warnings. Gonna fiddle with it with Inpa sometime during the week. Might even fix dis and do a test plan. My tires are 100% not overinflated or under. As I always have my shop air on. I tend to check my tire pressure more often than most.
No issue with tpms light. If you have constant tpms going on that is because you have to reset tire pressures by pressing tire reset button till tpms light blinks and then goes solid. As soon as you start driving, it will turn off. That will reset tpms. By the way, you can actually make the car be ok with 50psi by doing this. Haven’t tried it. But yea probably. Been driving all day. Everything works so I’m not really concerned yet. Lowers raises no issues. Compressor stays off till I make it do something. Hope crystal is fine as well. I’ll update here if I find something, as long as crystal doesn’t mind. I’m suspecting the line connection at the bag. Arnott didn’t send me 1 brass line insert thing and I had to reuse my original. They have since sent it to me, so I will probably start there.

Ie. I had height errors in my EHC for 2 sensors and 1 error in ABS for implausible height. (And remember our TPMS works off of ABS speed sensors) The TPMS is not experiencing a fault, just for some stupid I-Bus reason, it comes on It overrides any actual TPMS reset/use until the EHC issue is fixed. That one drove me up a wall until I recently fixed mine. Now a red TPMS, different story. That's a TPMS fault.

I’ve got red at present with all tyres within a half pound of pressure... have you found the cause?

My Driver's rear has been doing this for a few months. There's a problem with the bag most likely. I can tell because the compressor is activating even while driving, so it's got to be a fold in the bag thats sometimes exposed, letting air out which causes the compressor to constantly fill the reservoir. Getting the bag changed out at the end of the week.

I was on borrowed time. Red now drops faster and lower than Cardi B on dollar steak night!
The time has come! Both front bags now deflate after sitting. Will no longer air up and the fender flares are sitting on the tires. Compressor was beginning to run much more often that I would like (IE: while driving) so I knew it was a matter of time and the fun would begin soon. Question, do I do both front bags (unknown age on current bags) and the front distribution valve? Or just the bags first to see how that goes? Or vice-versa and do just the valve? How do I get the front end up enough to move the car without dragging on the flares?
