Rear end suddenly dropped! Daily driver :/ please help
07 s320 L
Hey guys
Does anyone know This problem and could help me?
I was driving 50 mph and suddenly Saw a bump , i barely Got slowed Down and took The bump Maybe 20 mph.
Right after that, i noticed The rear suspension being rough and very Bouncy, i stopped and checked and The rear end had dropped totally! Both sides
I drove home, and Saw airmatic malfunction light, restarted car, no light, drove slow.
When i drove normal speeds, light Would Come back.
Ive had a kind of noisey air compressor , so i noticed The compressor was NOT working, and The airmatic Rise button Either
I dont Think my pump is dead. Bexause The car has Been driving Great, and The drop Came immidiatley,
Sitting over Night The car has never dropped Low.
Also if The compressor stopped working, i Think it Would take some miles / bumps before The suspension Would drop - and then it Would be all 4 corners dropning Right?
Any help please guys

It happended Right after i drove kind of fast over a rather large bump
The Weather Here has Been -6 celcius degrees
Before that i havn had no Signs or indications of a bad strut, only a noisy compressor
If the rear leveling sensor rod has Been damaged, whats the cost of a new one at dealer, and How Many hours of Labour am i looking at?
Thanks :-)!!

Does it Sound Like a sensor?
Or is it possible that it is a strut / compressor? Going over a bump hard and suddenly rear drops immidiatley

Not to me. The sensor and link are really insulated from the suspension travel. I'd guess the impact caused one or both rear strut air springs to rupture. Probably looking at two rear struts. Don't drive the car if possible. Once the system is "open" the pump will run continuously and burn itself out.

If the rear end dropped and the pump is not running you have a blown strut (or two) and a burned out pump, or the pump blew a fuse trying to keep up. If the system is "open" meaning pressurized air is escaping as fast as its being produced, the pump (if it were working) would be running continuously to make up the lost pressurized air.
It needs to be towed to a qualified indie or MB Dealership for analysis ASAP. The dealer will give you a free loaner, not sure about the indie.
Replacement rear strut $541 each at Arnott, compressor is $481. Probably looking at around $2500 out the door if you need both struts and a compressor, plus a 4 wheel alignment. That would be worst case.

The pump and airmatic system was working fine, until it barely Got to Brake before a large bump, after The bump, i was driving slow and over The next bump i could feel rear suspension being Extreme hard, i Went out to check car and rear had dropped.
If i blew one or Two rear struts, would The compressor automaticly stop running? Wouldnt that also give me airmatic malfunction light immidiatley and after Every turn OFF / On engine?
Whats Holding the front strut up?
Ive tried once having a front left air strut being malfunctioning solenoid valve, and it needed replacement, but did NOT drop
I found This thread:
http://www.benzworld.org/forums/w220...-airmatic.html
It Sounds very Much Like my incident.. And it looks Like it Didnt cost more than 200 dollars to fix, could it NOT be possible i have same issue ?

It is what it is, regardless of theory. It needs to get to a shop for diagnosis. Hopefully it's minor but the fact it was fine one minute and not the next is exactly how AirMatic failures present themselves. They can have small leaks forever that the compressor can compensate for and you'd never know, then one day you get the screen of death and you're writing a 4 figure check. Let us know how it works out.

I think i might need a replacement on mine too................ Everytime i go over a bump, i feel it harder on the rear right. Height on the suspension is normal, no error messages, car drives smooth until i get over a bump and you can clearly feel the right rear suspension hitting harder than the left or the two fronts.

A workshop today i spoke to over The phone Said it Sounds Like a broken sensor and that they Are very fragile specially On Winter Weather, and The fact that The compressor stopped working immidiatley and Didnt keep working until it burned out bexause of a fracture On a strut
I have a time tommOrow morning and im crossing fingers that its a sensor and NOT a strut
Sensor Costs 150 dollars at Mercedes? Kinda alot

They will also charge for testing the air suspension system. I had mine checked last week and also 4 wheel alignment. I was also in to have all the modules on the car reset and passenger windows reset. My car was in the body shop for 90 days they had the doors off and all and trunk.

But my airmatic light only Came whilst driving; and i belive its bexause The car raises and and Lowers according to speed, and when it Comes up in speed and The rear is NOT responding; it gives airmatic warning.
The compressor stopped working AS soon AS rear dropped.
If a strut blew i belive The compressor would run until it Would burn or Blow a fuse
If my compressor stopped working, and i turn On car, i would Get airmatic malfunction immidiatley? And my front would have dropped slowly aswell , but its up.
Sounds Like a sensor i hope
