Disclaimer: I've not done BMW forks, only Japanese. I replaced the cartridges in my FZ1 with AK 20's from Traxxion. On my Tenere I used a shim pack, springs and valves from Cogent. And I've replaced seals and bushings(slides) in several different Japanese bikes for friends.
I've always removed the forks and disassembled them. Had to buy a few specialty tools, I now have a "fork" drawer in my toolbox. Unless it's a recently serviced fork, I replace the bushings and seals. Draining is easy, turn the fork over and drain. Pump the cartridge/damper a few times and it's empty. Do the same refilling, usually takes a minute or two. If I did this more often I could probably do a set of forks in a couple of hours. I will say it's a filthy job but with a clean workspace it's really not that hard with a little patience. Keep everything in line the way it came apart and replace in reverse.
All that said, I have no idea what the ESA adds to the procedure. Or how similar BMW forks are to Japanese. So, you should probably disregard this post as the inane ramblings of an old man.
