You can sometimes get lucky and do a brake fluid flush / replace and the codes can be cleared. Otherwise you will need to replace the two pressure sensors on the master brake cylinder... if you pull the error codes it can tell exactly which one has failed. ( i would do both since you are already in there)...REMEMBER buy BMW OEM parts... this is a difficult repair... so put the right parts in to avoid doing it again in 6 months

Check to see if your brake pads and rotors are in good condition. Or if you have replaced the pads yourself and have not reset the wheel sensors this would cause the ABS Antilock Brake System light and the ASC Automatic Stability Control light to stay on as the ASC uses the ABS brakes with computer assistance to control the car

You really cannot mis it. It is at the front of the engine, top center. Black can-shaped housing. Unscrew the top of the housing and replace the paper element inside.

NOTE: Some vehicles may
require the ignition to be turned on or to the second (or"accessory")
position for programming and/or operation of HomeLink. It is also
recommended that a new battery be replaced in the hand held transmitter
of the device being programmed to HomeLink for quicker training and
accurate transmission of the radio frequency. Please use a ladder and
do not stand on your vehicle during the programming steps for a rolling
code opener.
Rolling Code Programming:
1. Press and hold the two outer HomeLink buttons until the indicator
light begins to flash (after 20 seconds). Do not hold for longer than
30 seconds. Do not repeat this step to program additional HomeLink
buttons.
2. Place the hand-held remote 1-3 inches from the HomeLink button you want to program.
3. Simultaneously, press and hold both the HomeLink and hand-held
remote buttons. Do not release either button until step 4 has been
completed. (If you reside in Canada, refer to the "NOTE" below.)
4. When the indicator light changes from a slow blink to a rapid flash, release both buttons.
5. At the garage door opener receiver (motorhead unit) in the garage,
locate the"learn" or "smart" button (usually near where the hanging
antenna wire is attached).
6. Press and release this "learn" or "smart" button. (The name of these
buttons vary by manufacturer.) There are 30 seconds in which to
initiate step 7.
7. Firmly press, hold for two seconds, and release the programmed
HomeLink button. Do this procedure again and, depending on the make of
your garage door opener, do this procedure a third time to complete the
procedure.
The garage should now activate when the programmed HomeLink button is
firmly pressed and released. If not, give us a call or refer to the
"Troubleshooting Tips" noted below. NOTE: If you reside in
Canada, replace step three with the following: Press and hold the
desired HomeLink button and "cycle" the hand-held remote. To cycle:
Press and release the hand-held remote button every two seconds until
the indicator light changes from a slow blink to a rapid flash(step
four).
Troubleshooting Tips:
** Check the frequency of the garage door opener's hand-held remote
(usually found on the back). HomeLink is compatible with
radio-frequency devices operating between 288-399 Mhz.
** Put a brand new, store bought battery in the hand held remote.
During the programming process (step three above) the battery's energy
tends to drain (more so with an older battery). A new battery will
increase the speed and accuracy in which the hand-held remote sends its
signal to HomeLink.
** Retrain HomeLink holding the hand-held remote at different lengths
and angles from the HomeLink button you are trying to program (during
programming step three). Try 4-6 inches away at a different angle.
** Confirm that the HomeLink button you are trying to program is in the
"programming mode". Press and hold the desired button. The indicator
light will be a slow blink when HomeLink is in the "programming" mode
and can be programmed at any time.
Verifying HomeLink has picked up a rolling code signal:
** Press and hold the programmed HomeLink button. If the indicator
light blinks rapidly for two seconds and turns solid, HomeLink has
successfully picked up the rolling code signal. If necessary, proceed
with steps 5-7 noted above to complete the rolling code programming.

If you took this in and had BMW do the work to fix it and it is not fixed why do you not return to BMW and get it fixed, If you have paid for a repair and the repair did not solve the problem have them refund your money.
