HELP!!!! Inactive Suspension that wont go back up...

[gelafont]

i'm in a dire need of some help and suggestions here. I have an 03 X5 4.4 with the full active suspension w/ button on left side steering. Over the w/e I had my friend changed the two front rotors and brake, while on the lift I also had him checked this funny noise coming from the driver side rear wheel driving. This noise is not a squeaky sounds, nor a wu wu sounds, but more like a peck, peck, peck sounds that gets louder and constant as speed increased, and it's only coming from that single driver side rear tires. To replicate the noise, he had me start the car on the lift, and shift it to drive to replicate noise. While accelerating on the lift, i noticed all the lights started to come on the display includind the "Inactive suspension" message and a "max speed limit" message with a 35 or 45mph. I told him about it and disregarded the message and continued with the testing by taking the back tire off (accelerated some more, all messages are persisted) and finally narrowed it down and concluded the rear noise is coming from the rear wheel bearing, and it's going bad.

After putting the car back down from the lift. We noticed it went all the way down, and literally sit on the tire. Expected the car to go back up as usual, I drove it around slowy, all the light eventually went off, except for the inactive suspension message, and there were no green light showed on the left side steering button. We checked all related suspension fuses--glove compart and rear trunk (no blown fuses), unplugged battery for hours, drove it around again. Despite all efforts, the car is determined not to go back to normal level, the air pump won't buldged. It still sits on the tires, and wont go back up.

Any help and or suggestions would be greatly appreciated before i resulted to go to the dealer and get charged an insanely hourly charges to just reset or reprogram this thing. tks in advance!!!
