i got the pressure bleeder attached but the fluid doesn't run out on its own when i open the bleeder valve, any idea why? do i have a leak somewhere? the pressure is holding in the tank...

You only actuate the bleeder valve after you're done bleeding the system to de-pressurize the tank. If no fluid is going to the system when tank is pressurized (aprox. 20psi)
check your tubing connection. Also make sure siphon tube is connected properly inside the tank. Good luck.

Ahhhh....I ended up doing it the old fashioned way, by pressing the brake pedal to force the fluid out. I don't know what was wrong with the pressure tank, I'll have to check it out later, too tired tonight and I've got work early. Everyone mentioned that you have to becareful that when you connect the tank to the MC because fluid may spew out due to the pressure that is in the tank, but when I connected it I had no issue. I thought that I was just that good at connecting it, but after I had given up on the tank and I was empyting it, I was trying to force the fluid out of the tube by pressurizing the tank and then opening the end of the tube, but nothing even budged. Maybe there is a connection problem within the tank or the end connection (it was pumped up to 20 psi). Again, I'll have to check it out another time. Thanks for the help regardless. I was about ready to call in sick to work tomorrow

Sorry, I was thinking of the tank pressure relief valve. Just check the connection, specially the cap-tubing coupling.
Is the tube present and properly connected insidethe tank?

Rizbel

If the cap is not connected to the tubing via the quick disconnect coupling fluid will not flow because of the check valve.
The tank will remain pressurized. Connect the cap to the tube and fluid will flow out.

Anyone know the order to do a RHD car?

I need to do mine at the weekend

Is the pressure bleeder needed? Can you just pump in the new fluid by pumping the brake pedal? Is there some issues with a BMW doing it this way? That's how I did it on our old honda and never had any issues, except needing two people.

You can do it the old fashion way except for the fact that it takes two people to get it done . One to pump the pedal and one to bleed and make sure the MC is alweays full.

As a final thought, I personally think it is a bunch of BS regarding the necessity of changing the fluid unless you have a race car. Name any other manufacturer that has this requirement and don't say that BMW's are something special. In my case the dealer didn't do it on my car and I have a hunch it may just be a scam.

In fact my car will be 4 years old next month and it has been to the dealer twice for service and whereas the work order in both instances indicate a "Brake Flush", I know for a fact that it was never done.

If anyone takes their car in for the "Brake Flush" as part of the regular maintenance take some precations so that you can tell if they actually performed the flush.

Examples: (it may be worth your while to see if you actually got the flush)
1.put a twig or piece of black thread under the clamp holding down the houisng for the microfilter or some other method to tell if the left microfilter was actually removed.

2. put a piece of black thread under the weather strip at the rear of the engine bay to be able to see if the weather strip was removed for the flush.

3. put a small glob of grease on each on the bleeder valves to see if the dust covers were actually removed. In fact just remove the dust cover off of one the bleeders to see if is stilll off when you get the car back.

Awesome! I just got this warning on mine and was dreading the dealership. I know what I'll be doing this weekend!!

How much brake fluid do you need to purchase? I just got the warning on my newly acquired 2006 530 CPO and will need to do this in this next month or so...
