I have a Mercedes S500 AMG equipped with Airmatic system which is not working at all. The multipurpose display says, 'Airmatic, STOP, CAR TOO LOW!'. i think it is an electronic fault. Can anyone tell me which module controls the airmatic system?

 

is the ride height the same, or is the car sitting a lot lower??

 

vovpar, you speak the language of true experienced W220 guy now. i think you really did learn a lot.

once the red airmatic warning appears on the multifunction display, the airmatic system is dis-abled. actuating the switch might activate it, but if not... there's a problem.

if there's ride height problem, then a leak could be present.

if the pump is faulty or the valve is leaking (run time exceeded)... then it will shut off.

it is wise if he can tell us more about the symptoms.

 

thanks sleepwalker,
i have same problem with mine, but i mine is sitting all the way down and i need to do the coding.
cant wait to get the car done!!!

 

so it must be coding on the SAM, EIS, ESP to indicate if you got airmatic or ABC (active body control).

 

probably, i'm taking it for service tommorow, finnaly put everything back together and going to programm it tommorow.
Wish me Luck

 

i'm going to let you know what dealer says about this issue....

 

Dear Sleepwalker

Thanks for your reply, now;

First of all, the car is sitting too low. front tyres went inside the fender.

You said actuating the switch might activate it, how do I do that? where is the actuating switch?

How can i check if the pump is working or now?

What is the coding thing? how it works? I'm actually new with Mercedes but I am a techi, you can try me. Please help me with this.

 

then you got a leak. if both front are down with the same level (+/- 2cm), then the valve/pump must be leaking.

if the other side is a bit higher, then it's a shock absorber air leak.

the raise and lower switch is located in the upper control panel. it's together with rear blinds, anti-towing, etc.

the pump is located on the fron right bumper (concealed). you can listen to it or any hissing sound.

coding is what takes vovpar to dig deeper into his pocket now. it is programming the computer/control unit to recognize installed equipments in the car.

 

coding i not that expensive, but it adds up if you tow the car to the dealer couple times[:@]
