It was after a BMW-garage (in Oslo) changed the seals my gearbox started to leak into the paralever. I got the job redone in Germany (BMW-garage) and it still leaked. In the end I saw that none of the garages had plugged the hole above the sealing between gearbox and paralever… I would have checked it (and the breathing), it’s also worth checking that the seal is placed the right way (it’s different on a GS and a G/S).
When the paralever was introduced it was filled with oil (2 plugs partno 07 11 9 919 225), and some people still do it. IMHO it’s not a smart solution.
