Did pan/filter replacement and top off with BMW fluid at 118k miles back a few years ago and just did a fluid drain and top off again with BMW fluid a couple weeks ago at 167k miles. Reset the adaptations both times. So far so good. No sign of any leaks or slipping or other mal-operation. Plan to service the same every 50 to 60k miles and replace the pan/filter every other time so every 100 to 120k miles. Not really sure if I'm going to touch the bridge seals, Mechatronic sleeve, etc. before there's actually signs of a problem.
