Active curve system failed

1200 miles.... will update when I can take it to the dealer. Coming to think of it, it was probably faulty from day one, there was a very subtle groan when turning.

Active curve

We just won lemon law buy back because they couldn’t fix active curve. Same here: don’t think it ever worked.

Update

After a week of sitting at an airport parking, it mysteriously fixed itself! Even the faint groan during turns is gone. Fingers crossed.....

Mine kept showing "Active Curve Malfunction", had it checked out by the dealer and they claim to have bled the lines, and now the message is gone, but the car rides pretty rough. Maybe i'm imagining, but it seems like it's always set in the maxed out position... it never relaxes, even in straight lines. Can that be or am I just imagining?

Put the settings on sport, if that doesnt make the ride firmer, you have an issue with the airmatic system. On my c400 when their was a fault the suspension would default to the firmest mode.
