Thought I'd post the part #s you'll need for this if you want to do it yourself.
Firstly, our bikes come with a plug inserted in the clutch slave where the bleed nipple is inserted. You'll need to remove this with an allen key (not certain which size - very small, perhaps a size 2?). Anyhow, for obvious reasons don't remove this plug until you are ready to put the nipple in place.
You can purchase the bleed nipple and cap from Max BMW here :
It is called "BMW Hydraulic Clutch Fluid Mineral Oil" and is a funky blue color. It comes in 2oz bottles and is $11.06 per (and you thought gas was pricey these days!).
I purchased two bottles to be thorough - one bottle to completely flush the system, another bottle to fill and top off.
Easy as any other clutch bleed once you have the missing bleed nipple in place.
Hey folks- I'm a little confused about this- I've never heard or read about a need for this. I thought the clutch just required oil changes as it's a "wet" clutch?
They're talking about flushing the hydraulic actuating fluid, not the engine oil that the clutch itself operates in.
I'm not sure about the GT, but on my LT BMW recommends flushing out this fluid every year or two. But that was regular DOT4, which can absorb water over time and thus lose its effectiveness. I'm not sure what the recommended service interval is for the mineral oil used in the newer Beemers.

Prax nailed it - I think it's suggested as an annual thing which is what I do just to keep everything fresh, though the mineral oil schedule may be longer (dunno). I figure why not - it's cheap and easy to do (took me less than 10 minutes start to finish).
Grif, I did the Big Bend thang a few months back - weather was great for it in October so we made a run out of it. Nothing quite like the river road at sunset...
Plus, doing maintenance with a good ceegar and some jams is almost as good as peanut butter.
I love the Big Bend/Ft. Davis area. Unfortunately there will be an influx of about 50 State Troopers in the area at that time. Is 100 mph probable cause?
All kidding aside, it probably isn't suggested by BMW as a must do item if it's not showing up in their schedules. I haven't scanned the owners manual but I'm not certain if it's in there either. More and more auto manufacturers are calling their trans and diff fluids "Lifetime Fills" but after seeing some of those so called long term fluids after just 10K miles, I beg to differ.
For me, it's therapy. I was a keyboard jockey for wayyyyy too long so any time I get to use my hands and get 'em a little dirty, for me that's therapy. It's cheap - it's easy piece of mind - and it is required maintenance on every other bike I've owned over the years. Call it habit I 'spose given that last point...probably won't harm anything by not doing it, but it also doesn't hurt a bit to have fresh fluids whenever ya can.
I'd only call you stupid if you decided to never flush the clutch fluid, put 100K miles on your bike and wondered later on why if the bugger ever let ya down.
