Airmatic suspension stuck up?

Hi, My airmatic suspension is stuck up high, It happened about a week ago. Won’t go down, message on screen says visit workshop. I have tried driving over 60/70 for over 10 minutes to see if that would help. No change, still stuck up high. Lights on button on dash work, but no sound from pump. Is there any way to release the air manually or reset the suspension?
Please help

Not sure if this will work but you could disconnect the battery for about a half hour and reconnect it. This should reset the computer and associated electronics for the air ride. There is a down side to this. If you search on ” changing the battery” in the 220 forum you should find a procedure for resetting all of the electronincs and systems in the car. It is a well documented process. I did this when I had problems with the computer giving false errors and it fixed it.
Good luck
Michael

Try this procedure: On the climate control panel ENGINE RUNNING.
1. Hold the “Carbon filter” (lower left button drivers side) and the “Rest” button (upper left on the passenger side together until the display says “searching. ”
2. It will show an error code or codes.
3. Press the “auto” button on the drivers side so make it “pop” out. do the same for the passenger side.
4. Press in the PASSENGER side “auto” button to make it press and stay in then do the same for the driver’s side “auto” button.
If the suspension is stuck up because the systemn threw a code, this will clear the code. Hopefully it will allow the suspension to lower itself.
This will clear the error codes displayed.

i had a similar issue with my ’01 S500 recently. Try checking the relay making sure it’s working. could have gone bad and made the hydraulic pump stick. in my case, i wound up having to get a new hydraulic(airmatic) pump and relay. everything is peachy now!!

Hello my 2002 w220 left strut won’t come up and my cluster is showing airmatic convenience and airmatic sport 2. help please

You don’t really give enough info for us to make a really good guess. Things like, front or rear? What is the exact wording on the instrument cluster? Did the drop happen overnight, or while you were driving, or??

Unless you are wealthy enough to pay an expensive shop to fix your problems, your only choices are to learn enough to fix your own problems, or to sell the car.

There are several possible causes for your problem.
Unfortunately, the most likely cause is fairly expensive – the airmatic struts are expected service items. That is, they don’t last forever. The failure is usually a split in the fabric and rubber diaphragm inside the strut. It is possible to replace the diaphragm, but that job beyond the capabilities of virtually all owners and almost all shops.
Here in the USA, a company called Arnott rebuilds the struts (with a lifetime replacement warranty). They are available in several auto parts chains (Autozone, O’riellys, etc.) for about $350. Arnott also builds and sells new replacement struts.
Mercedes Benz sells new struts (expensive), and MB-rebuilt struts (less expensive).
You can buy really cheap new struts off of eBay, but that is a real gamble.
You might be able to buy used from an auto wrecking yard. Front left and right are identical, and rear left and right are identical. Another gamble – the usable life might be two weeks or ten years.

There are numerous YouTube videos on strut replacement – search for “W220 Airmatic strut”.

Another possible (but less likely) cause could be a failed solenoid air valve in the Airmatic valve block that simply isn’t sending air to the strut.

Another less likely cause could be that a level sensor, or its mounting, or its linkage has failed.

Here is a link to an excellent article on the Airmatic system – a study session would seem to be a good start.
