Removing and installing front side airbag crash sensor
Side airbag crash sensor on driver side -G179-/ side airbag crash sensor on front passenger side -G180-
Removing
  WARNING
t  Follow safety regulations for pyrotechnic components → Chapter.
t  Observe safety precautions for crash sensors (pressure sensors) for front side airbags → Chapter.
–  Disconnect battery earth cable with ignition switched on → Electrical system; Rep. gr.27.
   
–  Remove door trim → Chapter.
  WARNING
Before handling pyrotechnic components (e.g. unplugging the electrical connector), the person handling them must „electrostatically discharge“ himself. To do this e.g. briefly touch the door striker plate.
–  Pull out connector mechanism -5--arrow- and press down, then unplug electrical connector -4- from crash sensor.
–  Unscrew bolts -1, 3- and remove crash sensor -2- for side airbag.
Installing
  WARNING
t  Follow safety regulations for pyrotechnic components → Chapter.
t  Observe safety precautions for crash sensors (pressure sensors) for front side airbags → Chapter.
t  Before handling pyrotechnic components (e.g. connecting the electrical connector), the person handling them must ensure that he/she is „electrically discharged“. To do this e.g. briefly touch the door striker plate.
Install in reverse order, but note the following:
  Note
t  Ensure electrical connector is pushed fully onto stop and engages audibly.
t  For the crash sensor (pressure sensor) to function properly, it is vital to ensure that the door forms an effective seal.
t  All components (e.g. cover, speakers, door trim) must be correctly fitted.
t  The door trim retaining clips seal the system. If necessary, renew the retaining clips.
t  Ensure that no cables are trapped.
  WARNING
Battery must be connected with ignition switched on. If pyrotechnic components (e.g. airbag, seat belt tensioners) are repaired incorrectly, undesired triggering may occur after the battery is connected. Ensure that nobody is in vehicle when connecting battery.
–  Connect battery earth cable with ignition switched on → Electrical system; Rep. gr.27.
  Note
If airbag warning lamp -K75- indicates a fault following installation, event memory must be read, cleared and read again → Vehicle diagnostic tester.
Installation tips: for example tightening torques, renewing components → Chapter.
