Hello Everyone
I got 2019 G05, Has happened a few times when I lowered air suspension from the medium level to the lowest level and rear wheel keep calttering like a rattling noise. This sounds more like a metal knocking, but not all the time, It often happens when the first time lowered suspension after drove for a while but I raise or lower right after the sound will not appear. The vehicle engine is on in parking mode with Auto Start Stop Function on and AUTO H on as well.

Parked at drive way, not that flat but Definitely not big downhill, pretty sure the sound is not like compressor operating, I tried to turn off AUTO H function , the sound seemed to disappear, just curious can't operating air suspension when AUTO H is on ？

Kindly asking anyone has same issue incase dealer going to be advised me that normal but seems defect to me

I'm no expert but that certainly is NOT normal. I have air suspension as well and I've had the car for a year now. Never ever heard my car do anything of that sorts. I would be shocked if you brought it in and they tell you "it's normal". Definitely get it checked out. Good luck!

Thx, I will definitely bring it back, hope not big issue.
I thought could be AUTO H on caused the issue while realized car is in parked, AUTO H doesn't do anything at this moment.

It's likely the clamping pressure of the brakes calipers on the disc rotors that's creaking as weight of the vehicle is being redistributed while the air suspension is lowering in the back.

When air suspension is lowering your X5, it lowers the front first and then the rear. It reverses the process when raising.

When you're in park or auto hold is enabled or your foot is on the break, the car will sometimes make that sound while the suspension is raising or lowering. I've heard it once while sitting in the X5, but the sound was deadened.

If you're still concerned, have it checked out.

SAS groans and creaks when raising/lowering

Thank you so much, was really helpful.
I always parked and drop my suspension and most of time AUTO H is enabled and that's why the noise keep coming, but foot is not on the break since it's in parking mode.

I guess i have to turn off AUTO H to eliminate the issue, just wondering has always been this sound recently, it won't do any damage to the brake or rotor ?

Thanks your info again !

Same issue with me I thought it was broken but auto hold or if you step on the brake while lowering it makes that exact noise

With AUTO H, the brakes are engaged enough to keep you stopped but light enough to quickly let off when you press the accelerator.

I wouldn't worry to much about it in damaging the brake or rotors or disabling AUTO H when needed.

Lowering takes about 7 seconds from Normal to Sport and 17-19 from Normal to Load level. In most cases you're lowering when you're in Park or while driving.

There's more pressure braking (depending on speed) coming to a stop than transferring load weight vertically at standstill.

it's happens to the front wheel as well when I raising the suspension, but obviously the noise come from the back wheels are more intense when lowering compare to raising.
May I ask regard this sound is normal, why does it appear occasionally, No matter what I do, the sound disappears after appearing once for a while.

Thanks !

Try lowering the vehicle with no parking brake, no brakes applied, etc. Sounds like brake pads skipping on the rotors as it shifts slightly.

you mean Auto H right

Perhaps..... or the parking brake.... or just holding the brake pedal while lowering. Any of those could cause the pads to slip like that.
