Hello

I've got a ml 320 2006 with the dreaded Airmatic warning light that comes on after 20 minutes of driving. The front drivers loses a cm in height overnight (12 hours), and there is a knocking on the same side when going over bumps.

Could this mean new struts/springs?

Diagnostics (Carly) has the "reservoir is taking too long to fill up error"


Thanks for looking!

I don't know what Carly is but your diagnostics are short on teeth---you need to find someone who has a copy of DAS to get you out of this problem or you will be run around the parts may pole without a solution!!

Definitely agree... I'm getting it checked next week.

This is the output from carly.

AIRmatic (MB: 2515451832) Fault: Recovery time during filling of central reservoir is too long.

The carly is a mobile app... Output is below.

Well whatever, the data suggests that you have loads of issues--I'd make the Airmatic the last to look at!!
