Thanks JDGold47...I don't think BMW wants us to remove it but I always like to clean ALL the junk out of the reservoir on models that will allow the screen to come out. I prefer to remove all the old BF before adding new, otherwise you are just pushing old/new mix thru the system. I will also assume that the fluid in the reservoir is MORE contaminated with moisture that what's in the lines. just doesn't make sense to start with old fluid. Again, that's my opinion only.
BTW, I have a pressure bleeder.
I would think someone had figure out how to remove it. I may try sliding some shim stock piece down around the snaps to help. Anyone can jump in here if they have any tricks on this. BTW, a new screen is only $5, so may just destroy this one & replace with a modified one that will come out.
