I have a 2004 E320 and it says on the dash board "front passenger airbag off". How dod I turn this back on?

Once you have the dash out. The airbag module is easy to replace. You can not just remove the panel in front of the air bag.

Disconnection of the airbag will NOT TURN OFF THE LIGHT

Is this the passenger airbag switch?(some models allow you to turn the front passenger air bag off if you have a small child-just taking a guess)

Thi syear and model uses what is called a "Smart Airbag System" what this means is that the SRS system has a weight sensor in the passenger seat cushion, unless the object or passenger (a child) is more than 50 pounds the airbag is automatically turned off on the passenger side. There is no other switch.

WELL SOME CAR HAVE A SWITCH IF YOU DO NOT HAVE A SWITCH ON THE DASH THAT SAY AIRBAG PASSENGER SWITCH OR SOMTHING TO THAT YOU CAN NOT TRUNE IT OFF HOPE THIS HELPS

Under driver and passenger seats are wires that go to seat belt anchors.These are tensioner wires.Unplug the wires from the plug under the seat.clean and replace.Doing this while the ignition is turned off.Then turn ignition back on.In 90% of the time this is your problem.Constant movement of seat causes this or rear passengers kicking plugs off.Good luck phil.

you may not always have to replace sensors, but you will have to change the airbag module (usually under front seat, sometimes in middle of dash) To remove the passenger airbag you have to take out the dash.

it is positioned in the very centre of the dash board, behind the radio/Air con unit, it is bolted to the floor, you will need to remove the dash board and possibly the air con unit to access. once the module and air bags have been replaced it shouldnt need anything else.

Hi Rafal Joe here to help, There are two torx head screws on the back of the steering wheel. It takes a special Mercedes Benz tool to do so. After removal there are airbag connectors that need to be removed. Be careful not to break them, They are plastic.
