my 525 07 with the motion sensors on the top and i heard and readed somewhere that if your roll all the windows down, lock the door( alarm armed) and wait for like 1 minute or so, and just kind of wave your hand in the car, the alarm would go off right ?. How come mine doesnt, i had to wave or even cover the sensors several times to make it goes off. Is this normal ? Thanks

Read your instruction manual ....
The key to your question is that your Windows are down or your moon/sun roof is open.

Not sure if the alarm system comes standard on the E60. When you lock your E60 normally, does the red LED under the rear view mirror blink? If not, there is no alarm system. The remote keyless entry system may not imply the presence of the anti-theft alarm system (hood sensor, interior ultrasonic motion sensor, tilt sensor, siren, backup battery).
I just installed the alarm system in my pre-wired US-spec E90. To test the ultrasonic sensor, one must close all windows except the driver's. Arm the system (lock), and the LED should start blinking about once every three seconds. Wait about one minute for the ultrasonic sensor to learn your interior "profile" - shopping bags, parcels, child-seat, fold-down rear seat, etc. When you throw a towel into the vehicle or reach into the vehicle, the siren should go off.
If all windows are open, the ultrasonic sensor is less effective. Do not lock / arm the system twice. While the first "lock" arms the system, the second "lock" disables the ultrasonic sensor (eg if you have a pet inside).

How it works
The ultrasonic interior motion sensor is a movement detector. The ultrasonic interior motion sensor detects movement in
the entire vehicle interior. The DWA control unit evaluates the signal from the ultrasonic interior motion sensor and triggers
the alarm.
3 seconds after the last door or hatch is closed, the ultrasonic interior motion sensor starts its reference run.
During the reference run, the vehicle interior is "scanned". This allows any changes in the vehicle interior (e.g. objects left
on the rear seat) to be recognised. The correct function of the ultrasonic interior motion sensor is monitored by a self-test.
The ultrasonic interior motion sensor is operational 20 seconds after the start of the reference run.
2 ultrasonic signals are emitted at intervals of 65 milliseconds. After transmission, the echoes of each ultrasonic signal
from the vehicle interior are stored separately in a measured value field. The echo is then split into several subintervals.
Within each subinterval, the echo value of the two measurements are compared.
If an alarm condition is detected, the DWA control unit will trigger the alarm. The siren for the acoustic alarm is actuated
via the local data bus. The signal for the visual alarm is fed to the light module through the K-CAN.
