Problem Description and Possible Solution
The relay which turns the airmatic suspension pump on may fail causing the pump to run continuously. This can result in failure of the pump motor or a dead battery as the pump motor will continue to run after the car is turned off. Also, Worn airmatic pump mount bushings can causes noises in the front axle while driving on bumpy roads or a buzzing noise while the pump is running.

I just replaced the back drivers side air shock and it worked at first but soon came back down and car is very low. Can you tell me is there a fuse or something like that I can check?

Rattling noise and pump turning on and off when car door is opened. Car lowers down to the rim on rear of vehicle...unevenly (rt side lowers 1.5 inches more than left side but both are significantly lower than front). Car lowers after sitting just 30-45 minutes. Now pump doesn't come on at all and console displays airmatic - visit workshop message. Found out this morning that it could be the relays on the pump. Probably will change entire pump.
I have an s500 Mercedes 2000 and the car when the cold weather the car when I rise it arises whenever it wants to where can I find the AIRMATIC relay
Airmatic light on" too low to drive"
Relay failed in continuous connection mode, which burnt the 40A fuse as a consequence. Replaced both. also replaced similar fuse which controls the secondary pump as a precaution.
While parked the rear stays raised and will stay raised for weeks. But after I drive it for awhile it lowers. What is causing this to occur? What is the fix to this problem?
car was sitting on the bump stops one morning. started and could hear a clicking sound under right hood. it was airmatic relay. did not get it off in time for old pump. burned up pump and then fuse.
mercedes wanted 1800 for job, including part which i did buy from them for about 400. an indie offered 800 total over phone, then boosted to 1200 when i drove in, so i passed. anyway, did it myself without air tools or the best of tools, and no previous experience on this type system in an hour and a half. very easy and it worked. have actually even replaced an air strut since and need to do another which is also really simple. ordered strut online for only 355 though it is aftermarket it works great.
Airmatic workshop lights come on a lot after I changed the struts in the front, sometimes it comes on when I am driving down the highway and then it goes away will have it check when I can afford it. Just replaced struts which bankrupt me for a while.
Airmatic Pump Motor Fail Due to Sticking Relay
Turned off car and heard clicking noise and pump trying to come on. Unhooked battery. Will see if I can locate relay and replace.
I just brought my 05' s500 i brought it from auto shop in philadephia and it was hit from the fender all the way to the passenger door i had to wait 3 week just to get ot out because the auto shop had put new doors and fender in and painted it anyways i went to go pick up the car and i guess they park it and left the lights on it wouldnt start so i had to jump start it find out i see something on the dashboard that says airmatic need to see the shop its crazy i dont know if i have a 4matic because it has 4matic wheel and tires, its feel like i just threw away 7k
Rear strut was replaced by mechanic. I replaced the air compressor for the suspension along with the air valve block. Worked great for four months. Then noticed the comprrssor motor over working itself. Found out that there was a tear in the air line from the comprrssor to the valve block. Replaced the comprrssor, airline along with the hela relay. Comprrssor will not initialize. Judging by the diagram on the MB Service diagnostic program there are no other components to replace. Don't know what to do next. What could this be?
this is the second time. First failure was at ~60,000 miles
I have some problems with my s500. The Air matic Motor failed on me.the car have been seating in my garage for the past 2 years.
This is my email address. Daniaenter@yahoo.com.
I have a 2001 Mercedes CL 500
Had to replace the battery in the car and ever since then the key fob does not work
I changed the key battery.
The cars also slow to start at times and takes 2 tries.
When I open the trunk I hear the rear trunk motor working and running but it does not open the trunk.
Maybe all these three things are intertwined.
Oh and the sunroof going back as well.
I have an airmatic problem, I don't leave a mercedes dealership without spending $1500.00 plus, my car in sitting in the Garage.
