Mercedes A-class Airbag trouble

2013 Mercedes came in with airbag light illuminated,  a quick code read showed a fault with passenger side occupancy sensor. This sensor detects when someone is sat in the passenger seat and also their weight. This sensor is very important because if the weight of the occupant is small it will not activate airbag in a crash situation as it could kill the child.

Many owners with this fault may decide to fit an emulator to kid the car because it’s a cheaper alternative to a correct fix. This is dangerous because it tells the car that someone is sat in the seat and the weight of that person is an adult so the airbag will go off whoever is sat there.

This customer decided to fix correctly which requires the seat to be removed and the upholstery to be stripped.

With the new part fitted and coded in, the fault light extinguished. Job done!
