Its just the code from the vehicles spec on the BMW database. As stated above it just identifies that it was included as part of another option - normally sat nav.The person doing the admin at the dealer has just been lazy and copied the list out in its entirety for the spec on the AUC website.
Also look out for an item of specification called "Event", this actually means that the car was given a special inspection at the point of delivery as it was going to a special event - normally for a launch event, journalist loan or driving day and will therefore have been thrashed!
