I got the airmatic malfunction light. I have dealt with airmatic issues in the past. Have replaced the front and rear suspensions on one side, replaced the compressor, and the air valve. This time the problem seems to be different. The push the "raise car" button in the center console doesn't light up at all. It seems dead. I looked at the fuse in the rear compartment and it looks fine. Is there another fuse I should check. Would a bad relay cause the button to night light up or should I just replace the rear fuse to see if that's the culprit. If someone has dealt with this problem and already has the trouble shoot solution, I would appreciate it. Thanks!

Check the relay and fuse for the airmatic system. It should still light up so if not light is on power to the system is an issue.

checked relay and fuse... they are both good. i don't even know where to begin to check power to system. everything else on the car works fine. it's just the specific airmatic button light will not come on when pushed.

The system is cutting power to the compressor. Either the compressor has killed itself again as you were tackling the other leaks or there is another leak.



You should reset the system and scan for pending codes. If it fires up when you do, you know that the system killed power. Discconext battery if you don't have a scanner.

I'm all going off thag it still has power and the relay and fuse are good.

Recently I had a issue like this, about 3 months ago. It was the connector that connects to the height sensor located at the top of the front struts. I removed it and used a contact cleaner to solve my problem.

Can you show a picture of the height sensor? My car has been showing the "car Up Arrow" light ever since I bought it but all struts are fine. I hope its the sensor.

I'll try to do this, at the moment I am outside my country. I hope, on Tuesday I can post the picture here.

Sumit Bhasin

great. thanks.

Here are the photos of the connector situated at the front of the car. Unfortunately I do not know where are the rear ones. When I used Star Diagnosis scanner they pointed me the problem on the front right sensor.
I hope this can help you.

This is the front right

The front left
It has three wires, one is the negative, the other one has 5V and the other one sends the signal from 0 to 5V after passing by the sensor. You can also test the sensor with a multimeter to see if you can detect the continuity of signal sent by the multimeter.

We have a "Malfunction" message with a pic of an arrow pointing up under truck. Truck is making strange noise upon start-up that stops after a while. Don't hear the air pressure noises we used to. It rides very "bouncy." We plan to do the work ourselves. No error codes coming up aside from 420 - catalytic converter. Any info welcomed.

You need an mb specific code scanner. Try mb carsoft Ii from Amazon.

Youll need to to find out which strut or corner it is. Try the soapy water test or look visually which one is dropping sooner than later pls. You might be able to save the compressor.

it it will require replacement of the struts. Do the full unit in front in stead of piecemeal. Rock auto has best pricing or go to fcp euro for their lifetime warranty. Stick with Arnott or bilstein only. Do the sway bar end links whilst you are in there too.
