I did a search on this and couldn’t really find a straight answer..2010 cl550 4matic. Airmatic stuck in sport mode 85% of the time. When it fixes itself the car feels perfect..what are some of the most common causes?

 

@COUPCONNOISSEUR , faulty panel switch perhaps or the controller is stuck in diagnostics mode somehow (perhaps unfinished lowering procedure earlier?)? Connect SD and check for errors. Any other things not working or working not the way they should?

 

no panel switch..I have the android head unit installed..everything else is working as it should.

 

so you have an aftermarket radio that replaces the default lowering control panel, right?

jokes aside - check in Factory settings if you got the right model configured under "NTG Control Panel" - maybe somebody set it to NTG3.0 while you should have NTG 3.5.

 

I’ll give that a try when I get home. Thank you Although..sometimes it works as it should.

 

Not to be pedantic, but ...

cars have both springs and shock absorbers

airmatic is springs ... with additional raise/lower features

your shocks are called ADS (adaptive damping system) ... that is, variable damping and one damping mode is sport. Nothing to do with Airmatic.

 

not to be sarcastic...but how are you trying to help here?

 

ok, well then my damping mode is stuck in sport making my suspension remarkably stiff. Does that help?

also, I disconnected my android headunit and reconnected the original panel switch. problem persists, stuck in sport.

 

easy silly boy ... he doesn’t have an Airmatic problem, he has an ads shock absorber problem. Nice to know where to look, wouldn’t you think?

 

Solved. The 2 plugs that are mated(abs sensor, air spring electrical connector) were not fully seated.
