I am sure it is the output shaft seal. This was replaced when the original work was done.
Gearbox removal, healthy internals removed and put in my immaculate cases from my original gearbox which had a stripped shaft. Clutch plates soaked in solvent overnight to remove the gearbox oil which was all over it (bloody tatty second hand gearbox). All seals replaced. I know it was expensive but the mechanic knows these bikes inside out and I have confidence in his abilities.
They said they would replace the seal but can't do it untill the 26th. It's cutting it a bit fine for the Garmisch trip. Taking no chances and have booked European breakdown with the AA. I love the bike but it is the most unreliable bike I have ever owned, and I have had quite a few. It has been maintained better than any bike I have ever owned also.
I don't think I will buy BMW again after this bike. There comes a point where the price for character is too high.

If you are sure that the gearbox oil level was correct after installation of your rebuilt gearbox, then I'd say that 150ml is way way too much to lose through a 'normal' worn output shaft seal, especially in the time you're talking about. I'd be wondering about incorrect assembly - is there a seal actually fitted?

[cc mac]

I measured the amount of oil which I put into the gearbox and it seemed like the same amount which came spewing out when I pulled back the gaiter the day before.
Anyway, they said they will replace the oil seal which is fair enough but my confidence in the bike is not what it used to be. I am wondering if I am going to have to take a bottle of gearbox oil with me to Garmisch.

I've been told that BMW changed the spec of the output shaft seals some time ago because they weren't lasting. Mine went around 20k miles. The replacement never leaked. Even when the original leaked, it was nowhere near the amount that you're saying - the gearbox is vented so there's no pressure inside. Dunno if you can peel back the front gaiter enough to check on the seal, but I'd be tempted. At the end of the day the shop are going to fix it for nothing, so it might not really matter for you to find out if they fouled up. On the other hand, it's be a shame to fall out with a bike just because somebody made a mistake whilst working on it. (My guess is the seals still on the bench!)

The gearbox seal leaking is not the first straw, it is the last. The problem now is, I have to keep the bike because I have no spare cash to lay out on something else.
I love riding the bike, I love the looks. The engine seems robust but the gearbox and transmission are fragile. The hall sensors packed in outside my house as I was about to leave for the Ardennes, the clutch packed in and stripped the shaft with it. The silencer broke. Oil seal leaked all over the new clutch 3K later. What next?
Now I know what shafted means.

Yet some bikes have covered vast miles with very little problems.
Do you believe in karma?
gus

[cc mac]

Yes I do believe in karma. I must have deserved my 1100S with what seems like average reliability, but karma also gave me a fit blonde German wife so no complaints overall.

[minivin]

ah yes the problems with R11S's..... final drive seal blown at 10k, gearbox seal replaced at 20k, catalytic converter replaced at 25k, lower yoke clamp replaced due to severe corrosion at 30k, seized Tokico front calliper stripped and rebuilt with new pistons and seals at 40k, fuel tank electrical connector taken off and de-rusted due to no grease at 48k (was suffering fuel pump surging), final drive bearings loose and damaged final drive seal and once again leaking (and shag undoing the nut and torquing it to 150lbf/ft or what ever it is), and now just about to go through 50k this weekend with icky ABS and a catalytic converter buzzing away, I wonder whether it will make 100k miles Pazon ignition system and Mikuni carbs seem so tempting.........

[Boxered]

And yet, my recently departed 11s had covered 21k, without any issues whatsoever, except for bottom yoke starting to lose the paint, it was an 02 model, and I loved it
But i would have shifted it if I had any of your problems, let alone all of them
