Stuck in Airmatic Sport mode.

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?

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.

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.

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.

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