I assume you have the Dinan cold air intakes? I had them installed. I have heard that the filters inside the airbox can come off (some of the first ones are doing this). It is good the car recognizes this letting us know, and we don't go around driving the car without the filter in place.
It does make one wonder about $2500 airboxes with falling off filters though....
Just had mine refitted as well.
