Air suspension height?

[blake6551]

Anyone know roughly what the distance from the ground to the bottom of the wheel well lip should be at Standard height?

My X looks higher to me in all settings all of the sudden. Curious what others measure at. Mine is approx 32.5" in the rear and 31.75" in the front.

Approx 32" front and rear.

On 22"
Very High 33-1/2"
Hi 32-3/4"
Standard 31-7/8"
Low 31-1/8"
Very Low 30-3/8"

Ok so what happens if my left front is 31 1/4 but my right front is 30 1/4 after being parked for a day or so?

I measured because if you stand directly behind the centerline of the car it looks like it's 'leaning' to the right about a degree.

Is my air suspension failing?

I did hear a mysterious compressor sound (in fact it sounded like it was coming from the right front come to think of it, but I don't know if the location of the *sound* is relevant) for five or ten seconds immediately upon waking up the car a few weeks ago.

Best steps to diagnose?

AFAIK, "all air suspensions leak."

Assuming that is true, I'm not sure what you could diagnose, and you might be hard pressed to get this fixed prior to failure so long as the suspension levels out when you drive it.

In this scenario, if you go for a drive and confirm the issue still exists immediately after parking, then you would have a failure that needs diagnosed. At that point, I'd suspect a ride height sensor, and the front ones are visible without taking off the wheels, so a visual inspection would be the first step.

For perspective, when having my air suspension compressor evaluated because it failed during a mobile service visit, the tech told me to call roadside because it would likely be slammed to the ground and undrivable by the next morning due to normal leaking. I asked the tech if I could manually add air and he indicated I couldn't, something about the entire system shutting down and valves not allowing air into the suspension regardless of how much air was in the tank. While that does make it sound like you should get re-leveled over the course of a day, it doesn't indicate how often, and finding yourself re-leveled after a drive would still imply everything is working.

Well, I guess it's still functioning well enough by that criterion: just as you say, both sides were even (within 1/8" let's say) after a short trip. I'll keep an eye on it. But you're right, probably not going to get better all by itself...

My car had an air suspension leak that caused the compressor to kick on about every 2 minutes when I would start to drive my car. It was diagnosed to be a leaking compressor, and they replaced the compressor under warranty. No more noise making. Problem solved.
