520 d msport, engine management light is on, no faults logging in check control with I drive, no faults displaying when reading using Rheingold, maybe I am not using Rheingold correctly, but it does seem to be connecting.
Any ideas on what the fault light causes may be ? Or any ideas on verification of Rheingold use?

Thanks.

Has the Cabin filter been changed? Mine just came on this past week as well and no fault codes. My cabin filter was changed a little over a year ago. Looks like it's the cabin filter warning, however I plan on taking it to the dealer this next week or so.

Not changed, only 25000 miles on clock, is there much to changing it?

Thanks.

My cabin filter was changed under warranty at 12k miles. It would have cost me $465 according to the receipt. I'm really not sure how often it needs to be changed. Yearly may be?
