Tools that would be needed
Important Note: This was performed on a 2007 E60 550i, other BMW models may vary slightly. E36/E46 do not require the removal of the cabin filter as the reservoir is already exposed. (In this case, jump to step where reservoir is already exposed)
Use Allen key wrech to twist (not remove) and lower the rod so you can remove the cabin filter housing
Remove the plastic piece on the side (shake it a little and it will come off)
Once cabin filter is removed, twist the 3 nuts (do not remove)
Remove the 6 star torx screw
And finally to access the reservoir, you need to remove this trim piece, slide the top piece to the right and at the same time, push the right side bottom piece upwards and it will come off (some wiggling maybe needed)
Lay all the pieces you removed and make sure you do not loose any pieces!
Now that the reservior is exposed, remove the electrical connection.
Clean area around the reservior to make sure no contaminants will fall into the reservior.
Keep the cap in a secure location so you will not get it dirty
Important: Remember to use a plastic bag to sheeting to cover the engine bay, you don't want fluid all over the place (corrosive on paint)
Use the turkey baster to remove the brake fluid in the reservior, remove as much as you can but leave a little in there to make sure no air gets into the system
Here is a view of an "empty" reservoir
Pour some brake fluid into the reservoir
Connect the Motive Brake bleeder to the master cylinder reservoir (remember to follow the instructions printed on the Motive Bleeder, Do not exceed 20 PSI at any time.)
Now, Start with the Rear right corner.
Jack up your car and remove the wheel to expose the braking system.
Remove the cap to the caliper bleed screw and attach the catch bottle tube as shown.
Once the screw is released, the oil brake fluid (dark amber) will start to flow
After a few minutes, the fluid will start to turn blue (this is why we use the ATE Super Blue fluid.
And finally, when the fluid turns completely blue, you know that the system has been flushed (well, at least for that corner). Tighten the bleed screw and remove the hose.
