QuickSilver and Motordavid, I appreciate your comments. Over the weekend, I used some Orange-based cleaner with warm water to clean out my pressure tank, which is a garden sprayer with new hose and a pressure gauge drilled into the tank to monitor the pressure. There is still a thin film of transmission fluid, so I plan to buy a new one man brake fluid pump/tank from BavAuto. I use the garden sprayer apparatus for diff fluids, tranny fluids on my 2003 X5 and on my wife's Honda Pilot. Having two tanks for this purpose is smart, especially with possible contamination of brake fluid. Motordavid, thanks. QuickSilver, I've attached a link to making one of these pumps yourself. While it was fun to make it, I think buying one is a lot easier and the $20 savings by doing it myself cost me a couple hours in running around looking for correct parts. here is the site in case you have not seen it: http://www.bmw-m.net/TechProc/bleeder.htm
