Side airbag crash sensors, G179, G180
(in the front doors)
For the first time in the Audi A3 Sportback, pressure
sensors will be installed in the two front doors.
In a side impact, the deformation of the vehicle
causes a rapid increase in air pressure in the door
cavity. This increase in pressure is detected by the
sensor and signalled to the airbag control unit.
Rear side airbag crash sensors,
G256, G257
(C-pillar)
The two rear side airbag crash sensors G256 and
G257, which are installed in the C-pillar area on the
left and right hand sides, are conventional
acceleration sensors which are already being used
in the Audi A3 3-door.

Note
The airbag control system uses sensors integrated in the front doors, etc. To avoid any
impairment to the function of the side airbags, no modifications should be made to the doors
and door trims (e.g. retrofitting of loudspeakers).
Damage to the front doors can cause impairment of system functions. All work on the front
doors should be referred to a specialist workshop.
Belt-on indicator
The new Audi A3 Sportback has the belt-on indicator
function for driver and front passenger as known
