Mini Cooper D, 1st Service (20.000)… normal that so much to do?

Hello to each other! Since the end of October 2008 I call a Mini Cooper D my own. I drive already for professional reasons a lot, so it was now on last Tuesday… the first service (20.000 km). Service was done quickly… but then came a call. My Mini Cooper D would have the typical Mini Cooper D disease (?): He loses oil on the gearbox. Aha. Ok, goes on warranty, so let me make it. Today I called when I would like my darling wi The gearbox had to be taken out, it was found that too much fat was lost/was lost in the clutch (?). You have already made a request to BMW because of the warranty. As soon as the OK is there, it is also done immediately. Aha. Well, if it is possible to guarantee it. So we call again tomorrow. Says, is this normal???? I only have my Mini Cooper D since the end of October 2008! Ok, I drive a lot… that immediately what must be done on the gearbox and on the clutch???? Is that normal???
