I'm getting a message saying "airmatic....visit workshop". front of the car is real low too.

Then do as it says. Thats what it's there for!!!

Hi I workon these all the time. The suspension works on air and the diaphragms burst constantly. I have to change them on cars with less than 4000 kms on them. There are other things can make tham low, sometimes an electronic malfunction can be reset and it gives no problems after that. but my guess is one of the diaphragms. A complete suspension unit is around $800, unless its an armoured car then they are $3250. One other thing, it is unsafe to drive n the road in the low condition. you have no suspension and the whole thing is unstable.

My Mercedes did the same thing. I got a air message and i noticed my rear was dropped. The air suspension had went out in the rear. It was going to be very costly. Then a friend told me about Strutmasters.com about getting a suspension conversion kit for the whole vehicle to take out the air and puts my car back up and cost me under a grand. My dealership quoted me 3 grand and up. Not only did i save money i got a lifetime warranty so i don't have to keep fixing my car.

yesterday i replaced both airmatic on the back but it doesn't go up i don't know what stim put new fuses here and also relays and still nothing my mercedes S 500 wanted to advise how to do it i don't know how to do it
