a while ago there was someone that posted , how to reset the MASS AIR SENSOR. (the sensor near by the throttle body)

the step was turn with your key on first position and wait 10 second, after 10 second return back to same position for 10 second. after 10 second start engine.

1)how can we check if the reset is completed, does it shows on the panel ?

2) during the reset procedure should the headlight (xenon) be on, or all the lights should be off.

3)last question, is the procedure same with 330ci .

i do have notes that after return to OEM airfilter (box) the RPM either drop below 1K or it would bounce up and down while i make a hard stop or make a turn with hard stop .
