It might be nothing more than loose bolts. Check them first, I seem to remember one or two posters finding them loose. You'll need an 8mm wrench.

The recommended torque is just 9 Nm (6.64 Ft/lbs), little more than hand tight, don't overtighten.

If you need to replace the gasket the cover is nothing more than a cover, there's nothing attached to it and it comes off easily for gasket replacement. A new gasket is part number T1260969.

I reckon that's what it is too as have been chasing this annoying leak for ages and have finally nailed it down to this seal

the leak on my bike looks exactly like in your photos

Made sure all if the bolts were tight. It's hard to really find it because it isn't a pro dominant leak from the o ring but I suppose it weeps a little and eventually collects underneath the gearbox cover. I'll call the dealer today and I might even have them come and pick it up since it is inconvenient for me to get it to them. Since the bike doesn't even have 3k on the clock yet I don't think that is an unreasonable request.

Your pics look just like mine. Did you ever get it fixed? What was it exactly?

Thanks.
