How to reset BMW E46 airbag light by yourself

Many people said that their bmw airbag light on after some changing:

  • Replacing the seat occupancy sensor.
  • Replacing the steering whell buttons.
  • Removal/replacement of the driver’s door airbag.
  • Any other changing…

Now i share a simple method to reset BMW E46 airbag light by yourself.It just costs you $20,else if you go to dealer spent more than $100.


Tools you need:

BMW INPA K+DCAN USB Interface $15.99 free shipping

BMW 20 Pin to OBD2 16 Pin Connector $5 free shipping

(If your car is after 2000 and with an OBD2 16 pin port, you can even save this $5!)

INPA software (Come with INPA cable)


Step1:Connect this BMW INPA K+DCAN USB Interface with your laptop USB port and the DLC Diagnostic Link Connector port.

(Since my E46 is before 2000 without the OBD2 port and the DLC port is a round 20 pin connector while INPA cable has only 16 pin connector, so I need a 20 pin to 16 pin connector.)


The DLC port location on BMW E46:


Step2: Install and run INPA software on WIN XP. Turn on the ignition and click the “F2” button. And choose “Body” section then “Airbag”.


Step3: Go to the Error Memory: click the “F4” button.


Go to clear error memory: click the “F2” button.
