Anyone changed fluid in DCT transmission?

Has anyone changed the transmission fluid in the 135i with DCT yet? If so could you post directions on how it is done. Thanks!

I thought the DCT was a dry clutch system.

EDIT: it appears that I was wrong, it is a wet clutch system.

EDIT 2: from what I can tell it's a closed system, but as we've seen I'm not always correct...

I did a search and haven't seen any DIY. Has anyone done this themselves or had a dealer do it. If the former, can you point me to a DIY. If the later, how much $?

I checked with my dealer. Although BMW says not to change it my SA stated they would do it if I requested. The price? Well it was over $1k. The majority of that was for the DCT fluid. Guess they have to special order it and its not cheap.

I heard it's actually condensed unicorn tears so that adds to the cost.
