Do you still have the problem? But you DO still have a problem. I wouldn't trust cleaning out the booster. Once the booster diaphragm is contaminated with brake fluid its only a matter of time until it fails. In regards to the orig problem I've read: The brake pedal position sensor relearn procedure will need to be done as well as the steering angle centering relearn. A TECH2 scan tool is needed to perform the recalibrations. HTH
