Airmatic HEADACHE with ADS




My Star system tested them perfectly but the Launch tested rears but failed the fronts… a day wasted of trouble shooting .
what model Foxwell do you have ?

OBD Scanner thread
Here's the one I got. I also purchased the VAG package as well. It was $80 USD. It covered VW, Audi, Seat, Skoda, Lamborghini, Bugatti and a few other VW cars. Its nice that you can purchase different manufactures and upload it all on the device. No PC needed.
When it comes to airmatic, all the scan tool does is focus in on the parts where you should be using your eyes and ears to diagnose the system.
for instance, you will both hear and see leaks, and see bent level arms. You will hear a bad compressor. You can reason your way to a weak compressor by how long it’s running. One thing I do find the system useful for is measuring pressures.

Nice thing about Amazon is you can return things very easy. I went though about 4 different scanners ($200-400 ranges) tried it on the Benz for a few days, didn't like it, returned it and bought another. Tried it, returned it. Nice way to "test" a scanner out lol

consider it the non-standard programming module for doing whatever you’d like to your car vice only the options that are presented to you.

Your front struts combine both spring and shock absorber into single units. At the rear, springs and shock absorbers are separate items. Since you have Airmatic, your springs are air springs, rubberized canvas bags filled with compressed air.
As at the rear, there is ZERO connection between the shock absorbers and the springs. At the front, there is also ZERO connection between the two. ADS is simply a system that adjusts the hydraulic oil flow within the shock absorbers. Again, there is ZERO connection between ADS and Airmatic.
As regards ADS, nothing about this system affects ride height of the vehicle. it simply makes shock absorber motion either soft or hard (and there is a normal position) to make suspension performance either comfortable or sporty. These adjustments are all accomplished electrically via solenoids on each shock. There is no air pumped into the shock absorbers.
Any malfunction of ADS components simply means shock absorber performance is compromised. No malfunction can affect vehicle ride height, nor can it affect any component of the Airmatic system.
Vehicle ride height is solely a function of amount of air pumped into and retained by the air springs.
ADS for sure makes cost of front struts and rear shock absorbers more expensive. Again, there is no connection to the electrics that operate filling the Airmatic air springs.
To save $ purchasing struts and shocks, you can fit non ADS versions. It's a pretty bad idea, as this is a wonderful option. Fixing problems by removing the component is pretty trailer park.
The air pumped into Airmatic springs is determined by inputs from the switch of course, but on a daily regular basis by four vehicle level sensors, one mounted at each wheel. Not, not, not by your shock absorbers.
Hope this somehow helps. Obviously you know some or all of it, so apologies if that's the case.




The problem was solved with a level calibration set back to factory specs . Changing and variety of parts EVEN A COMPRESSOR can throw off the level calibration. Many will say NO i changed a compressor and nothing bad happened… me too. I changed a comp.. in two other vehicles with no issues. But the third one was trouble .

Sorry if my question is different, but I hope someone can help.
I am getting Y54/1 error and Airmatic Malfunction on the cluster. This code is for rear right ADS. I changed the shock with a brand new Bilstein but the code persisted after clearing it. Took the car to the MB dealership and they said they needed to test communication from the airmatic control unit to the shock. The control unit appears to be in a very clean state upon visual inspection.
My question is, what tests can I perform at home? Or should I just buy a used Airmatic control unit from eBay, swap it in and see how it goes?

How much are you asking for delivering to Massachusetts?
Also, I am unsure if my controller is bad or not. Can I return it if it doesn’t solve my problem? 😂
