Ok Fellas, Need some assistance... I've searched the forum for this topic many times, learned a lot of things, but would like to see if anyone has experienced this on the 211 amg... The front end sits just fine, looks the way it should... The rear end is hit and miss, sometimes it'll look ok, and sometimes it'll sag down to where it looks lowered... I dont get the airmatic too low message, and ride quality isnt affected... I can raise the vehicle, however it'll just come back down eventually... Is there any way to visually inspect if it may had been lowered previously? I plan on taking it into the dealer, just want to make sure it's not modified and cause a hassle in warranty... The MB warranty is expired, I'm currently covered with a Diamler Chrysler Maximum Care Contract...

Any help will be greatly apprecaited!

Thanks,

P.S. I'll post a pic in about an hour when I get back from lunch...

its happened to my friend. One day he goes into his garage and he sees the rear really low. It was a leak in one, and the other side was blown. Had to get the air suspension for the rear replaced.

Thanks for your reply, and your sugestion... I have an appointment made with the dealer tomorrow, we'll see how it goes...

Thats definitely not right. Let us know what the problem is.

Sorry to dredge up an old post.

I have the same issue, but the 07 e63 only looks slammed after 2 weeks without use.

Upon start-up, the vehicle will raise to normal height and stay that way after parking.

Is this a normal function of a typical pressurized system after 2 weeks or is this slow leak going to overwhelm the pump later?

Any help or experience welcome. Thanks!

Yes, it is normal for the system to bleed after a while if the vehicle is not in use. And as you mentioned, it should return back to normal once you start using it again.

This has happened to me, one side was dropped more then the other, and it turned out to be a blown rear strut on my E63. Yes, your right air will eventually leak out during a prolonged periods. And the rear should be level on both sides.

In my case above, it turned out that the previous owner had adjusted the suspension settings via star incorrectly. This is what caused the back end to sag compared to the front. The dealer reprogrammed the computer and performed an alignment... She's been good since!

Actually according to MB bulletins, the leak is inconsistent between all 4 sides, which means you could end-up with 4 different settings on all 4 corners after a prolonged period of non-use. However, after the car is started and in use again, the system should adjust accordingly.

Thanks for the quick replies everyone.

Would you please help define "prolonged period of non-use"? Is two weeks a reasonable period or an abnormally fast bleed period?

I just want to fix issues before they become major problems.

aldoe

Sorry to bump this thread up again.

Anyone know if two weeks is a normal period for the leak? I need to know if I have to bring this to the dealership before my warranty is up.

I've had prior issues with my dealership, so I'm trying to avoid getting more rattles than fixes there.

Thanks in advance.

it sitting for two weeks and leaking is normal.

question????

what about loosing air overnight? it will raise back to normal upon start up....

X2Board

Overnight. Sounds like you have a leak in the system, get it checked out before you end up needing a pump too.

TopEndS62

thank u sir!!!!

+1 Overnight depletion seems way too fast. Mine usually takes a 1 to 2 weeks before it gets down to that level.

I have gone over my Airmatic, and I have replaced one front strut.
No (ZERO) leak down in 6 weeks, but at 8 weeks ride hight looks OK, but the pump runs a bit when I touch the door handle.
Leak down over night, Huge Leak
Leak down over 2 weeks small leak, that will turn in to a larger leak. (cause they never heal up) this is how my strut failed. It had a really slow leak (AKA 2 week leak) then one day I hit a 2 inch ledge in the pavement from construction, and that made my small leak huge (blown strut)
So if your car leaks down over 2 weeks or less, be ready to have the air Matic worked on.
Any leak will cause the pump (AirMatic compressor) to fail prematurely and check it's air filter too.

Mine does look a little lower after one week, then noticeably lower after two weeks. But as soon as I start using it again, it goes back to normal. Do you think I have a leak? What causes the leak to begin with?

220S

fwiw, I have a new 2009 with low mileage on it and this is how mine is. Nothing visible even after long sits. When the car door is opened the system makes some small adjustments. It seems to work according to the SAS posted above and the owner's manual.

MB_Forever

How long have you left it unused? Do you think there maybe a difference for the performance package suspension?

220S

^^^
Longest was three weeks. I think the P30 is the exact same system but just tuned to have different air volumes in the chambers for stiffer dampening.

Yacht Master

That is how mine was and I thought it was normal. I had suspected the passenger side front had a leak because it would be a little lower than the drivers side. So I always had doubts for more than a year.
I think the cause is use, and personally I think the bellows/ rubber used in the air chamber is prone to getting pin holes and when a substantial impact is applied the weakest part "pin hole" gets larger.

The aftermarket arnott replacements have what looks like a much better quality rubber component. I don't know first hand, but you can't beat their warranty, Lifetime.

All that said, it would be hard to find a "2 week leak" so just keep your ear to that compressor and how long it runs when you open the door.

Well yesterday, I had my right rear air strut replaced under warranty. The right rear was riding a little lower then the left. The left rear was replaced last November. I really do think that Mercedes should replace these things in pairs under warranty. But of course they won't. The bottom line is no money out of my pocket, and that's always good.

aldoe

After reading the advice, I'm worried about the leak becoming larger. My warranty is almost finished.

Does anyone know if the dealer will replace it without being able to show leak? (i.e slow leak)
