Fellow Marauder owners, a while back someone wrote that there were 4 software updates for our cars, with codes FDH2, BMD0, CRD0, and CRD1 mentioned. Question, can you just have the latest (CRD1) applied or do they all have to be applied in succession?

Also what exactly do they do to the car? Didn't someone say something about smoothing out a rough idle during a cold start during the first minute of start up?
