When i got my 2003 E39 530d auto a year ago i took out the swirlflaps the same day i got the car. Read any UK forum and you will find that they urge you to remove them as soon as possible in order to prevent damage from flaps coming loose and destroying engines/turbos'/cats. Can't go wrong by removing them. Funny enough the 2003 X5 auto does not have flaps!!
