Hi I just got an e550 One owner and 80K km with Air suspension.
Every morning when it’s cold the car sits low only in the rear, this happens overnight.
I brought it to Mercedes and they seems to have changed everything but it’s still happening even faster when left in sport.
I have no warranty but they took it in for free as I just got it from Mercedes.
I need help as I see them stating that this is normal when cold when I call them again for this.
They certainly replaced a lot... including items that would be suspects. One thing to verify is it a leak or is it a commanded lowering of the car. Follow the document konigstiger posted: LI32.22-P-048597 and perform it two ways.
First, park the car on relatively flat surface, lock vehicle and keep key at least 15 ft away, come back in a couple hours measure all four corners, let sit overnight (or less if the suspension drops quickly), remeasure.
Second, repeat the above, but after parking the car, disconnect the electrical connector from the valve body (tucked up behind rear bumper).
If during the second test the car drops, then its likely a leak somewhere in the system. One thing to check is the air lines, spray them down with soapy solution. On my wagon it was a chaffed air line in front of the spare tire tub.
Also can you confirm all the parts that where replaced? I don't see the rear air springs on your invoices... seems like just the compressor and rear shocks.

+1.
I noticed the same. It talks about shocks, not springs. Bad shocks do not cause car go down. If you look at the air springs they should look clean as the picture in konigstiger's post show.
WOW, I would not imagine a car would sit that low aside from a low rider mock ups
Sorry, I can't help but our mighty expert already helped you out
It really goes this low when the spring(s) leak. I know from my own car.
It does not mean both sprigs have a leak. If car is left in sports mode it goes all the way down on both sides but if in comfort or raised mode the one healthy spring generates enough pressure (as it has enough stroke to go) to keep car from going all the way down.
You are correct but you would think of it was the reservoir all four corners would be down! It’s only ever the rear that drops.
Reservoir should have nothing to do with this as each air spring has its own valve.
A valve leak, air fitting leak, air tube leak or leak in the air spring is the problem. Difficult to believe to have issue like this after they "replaced everything" unless they did not and just printed the paper to show that.
If all parts were replaced like paperwork suggests (it does not say springs were replaced though, only says they need to be changed) then the likely problem is leak in a fitting (tube to fitting) at spring or valve block or the tube itself between valve block and spring has a leak. If there was an issue with compressor or the reservoir there would be problems also in front.
You first need to check that the air springs really were replaced and if you find that this did not happen then there is no need to troubleshoot any further until they are replaced.
Going on “Read through attached bulletin for what they didn't do.” Response “It looks like they have already replaced everything!” Dealer needs to revisit but “seems” BitcoinKing may be reluctant or wants to try hands-on before committing to revisit.
Damn you guys are scaring me a little.
They can print an invoice without actually doing the work!?
I come from an e46 lol I have shocks and spring in the rear of that car!? Thought I had airbags. They mentioned something about changing the airbags I am assuming those are not the springs?
I will look in the morning because I thing I can easily locate the springs I thing I already saw it one day will just check if they are new.
isn’t it weird that they didn’t change both?
also their fancy computer can’t easily tell which one leaks!?
Konigstiger What is option 871 on my car?

You have springs and shocks in the rear axle. The spring you have is an air spring, which they call airbag, i.e. airbag and air spring are the same thing. All the parts they changed should look like new as you have hardly driven the car.
As you go checking the air springs also look under the back bumper slightly on driver's side. The valve block is there very easy to see with all the valves and plastic tubes connected to the valves. You may want to see that this part also looks like new.
If your car does not have the electronically adjustable stiffness, like I have in my car, the shocks are the cheapest part to change. The valve block cost $380, an air spring is about $550 a piece. The shock without the control is just a normal shock and those are quite cheap. I don't know the pricing for those. Shocks with the control are like $700 a piece that I would need to shed if I replaced mine. I have not done that as they still seem to be in good condition but some day...
If you find the air springs have not been changed and then the dealer starts saying that you would need to pay for that repair be prepared for around $2500-$3000 bill. If you are hands-on at all you can buy the Arnott made air springs for about $550 both and the job to change them is super easy.
Konigstiger posted the details of my vin is it possible to know if I have the electronic ones?
also is it the same set up in the front?
I attached your datacard based on the VIN. You have option 489 AIRMATIC DUAL CONTROL / AIR SUSPENSION SEMI-ACTIVE. To the right of the command knob, in the center console, is there a button for Sport / Comfort like this:
This controls both the ride height and the damping. Comfort is default and in Sport the car is lowered and the damping is increased. Front struts and rear shocks have electronic valves to regulate damping.
At the end of the day, you just bought this car from dealer, correct? The suspension dropping that amount is NOT normal, regardless of temp. If they don't want to fix it or whatever and you still want the car... then you'll need to dive into it. The comment about the invoice, is simply, it doesn't seem to show the replacement of more than just the compressor, some ancillary bits related to compressor and the rear shocks. Maybe your missing some paperwork or you didn't take pictures of all of it.

From some parts search I understand that there is an Airmatic model without the dampening adjustment in the shocks. I have not seen a car like this but I think there is.
I am shocked!
it looks like absolutely nothing was changed!?
One for Mr BMW
Your dealer lied their *** off. I would go to them to make them eat their BS.
You have the two stage shocks too and they clearly say that they replaced them. They are the dirtiest ones in your picture and surely has not been replaced. And they are a Mercedes Benz dealer working under the Mercedes Benz name.
Send your pictures to MBUSA with the pictures of the repair bill and ask them if this is what they mean by “The Best or Nothing”.
For the quick fix, get the Arnott springs and change them out and be done with it. You won’t get anything done by the sorry *** dealer you have to work with.
Would be difficult to trust them even if MBUSA gave an open check to have this all fixed. I could not trust a dealer like this. They could easily cause some other problem in the car that you would have to go in for.
