Just wondered if any one experienced this one Message centre showing check brake fluid, hdc inactive and air suspension inactive all just appeared and are not working Did reset at first once I turned ignition off but now permanently on. Have checked brake fluid its level is ok.
 
I guess it is an L322....

Time to get it on Diagnostics.....also check the connections to the ABS ECU, they can corrode.
 
Just fixed it myself, pulled plug on brake fluid reservoir put back and all faults cleared , I can understand it being tied into HDC control but the air suspension operation ? So easy for these things to cost a fortune.
 
it's the same in reverse if you get an air suspension inactive message, it can also trigger hdc inactive and abs faults, strangely when i had all these issues popping up, it started with an engine failsafe mode warning caused by the main engine ECU going faulty
