Have a E90 323i BMW. Was bumped in the left rear door and my side airbag poped and now the car wont start. How dow i reset the car cause the ignition swiches on and when i start it gives a click sound like a flat battery. If it is the jump off cable i tried plugging it back and still does the same.

Air bag needs coding, or re fit original one

yes call your dealer

Each manufacturer has different reset procedures if you can't take it to a garage and reset by odii ecu computer routes.forums for your make and model will suggest something similar to leaving the driver door open and then hold the courtesy light switch at the bottom of door before turning on ignition.turn on ignition one click but don't start the car.then release and press the door light switch say 5 or 6 times within ten seconds on the last count hold it in and turn off the ignition.close door then start car.sometimes you need to experiment as the number changes with different models.my car resets on 7 presses and I have to close the drivers door and open passenger door before I start car.

not normally the controll unit yes and the poped air bags but the rest will be ok the controll unit stores any accidents and will have to be replaced it cannot be reset

Hope this helps:- Factory Disarm Purple/Yellow (-) Driver's Kick Panel Black Connector at ECM -slice into this wire, & wire it to ground, this disables the alarm.

try looking at the ignition lock/starter relay.as a fist step.

to reset light brake sensor must have been replace close door turn key on but dont start car when time is displayed on instrument cluster press and hold button on left side of cluster a orange triangle will appear keep holding next service function will be displayed release button to scroll through services that can be reset just push button again without holding when rear brakes are displayed on cluster press and hold button again the message reset with a question mark will come up release button and then press and hold again and light will reset

Hi , to reset the service light you will need to insert the key and turn the ignition lights on but do not start the engine. you will see a push button on the lower left side of the instrument panel press and hold this until you have a triangle appear which then turns to the brake warning symbol , release the push button then press and hold the bc button in the indicator arm until reset appears , release and again press and hold the bc button until you have a moving clock symbol appear , release the bc button and wait for the display to change , once this has reset turn off the ignition and the service symbol should have reset . you may want to print these instructions before resetting , regards Mark.

this may be a problem with the actual door lock itself or the general module not sending an open signal to the lock
