I checked the colour of my oil by undoing the plug a little - still lovely and golden. On that basis, I was going to leave well enough alone.
However, having seen the informative thread on here, and always looking for something to do on a wet winter weekend, I may just give it a go. Call me sad, call it unnecessary, but I find a great way to spend a few hours on an otherwise boring day is change all the oils - engine, gearbok and (now) final drive.
BMW changing their service routine does make me wonder whether they simply made a mistake before.

With 8500 miles on the bike,the rear end oil was dumped,cloudy in appearance,some fuzz on the sensor but all in all, no chunks.
