i did figure out that there has to be 2 mechanisms at work in there. i took apart the actuator unit today and had someone press and release the parking brake. the mechanism travelled up and down freely and everything was in good working order except the brakes were not functioning! even thought the icon on the dashboard lit up the car still rocked when rocked back and forth (i has the ignition in position 1...pressed Start without the brake pedal) I also read the error memory and it had an error in it...something in german that looked like vehicle roll or something. I'm gonna try re-adjusting the sprockets in the wheels and see what happens.
