Recently the electric window winder on my BMWZ4 drivers dide was replaced.Since this has happened my airbag light stays on.Could this have been anything done during the winder replacement.

I experienced the same type of issue with my Corolla and I took it in and turned out it was a connection that had come loose. Also, check to see if there are any recalls for your airbags or sensors. That was another issue that mine had.

you need to get in touch with toyota they had a recall on your vehicle due to airbag.THE STEERING COLUMN ASSEMBLY CONTAINS ELECTRICAL CONNECTIONS TO THE DRIVER'S AIRBAG MODULE HOUSED IN A SPIRAL CABLE ASSEMBLY, WHICH INCLUDES A FLEXIBLE FLAT CABLE (FFC). DUE TO THE SHAPE AND LOCATION OF THE FFC'S RETAINER, THE FFC COULD BECOME DAMAGED WHEN THE STEERING WHEEL IS TURNED.
Consequence: IF THE FFC IS DAMAGED, CONNECTIVITY TO THE DRIVER'S AIR BAG MODULE COULD BE LOST AND THE AIR BAG DEACTIVATED. THE FAILURE OF THE DRIVER'S AIR BAG TO DEPLOY IN THE EVENT OF A CRASH THAT TYPICALLY NECESSITATES DEPLOYMENT INCREASES THE RISK OF INJURY TO THE DRIVER.

there are airbag connectors under the front seats. I have had an experience with another car and found faulty connectors, Because it is happening all the time, I would start looking at the Drivers side first. Maybe change the connector or add a piece of wire around the connector. Not the switch in the seat, jus the wire connectors,

You need to access the Airbag ECU (Electronic Control Module) using suitable diagnostic equipment connected to the data link connector of the car in order to erase all faults - DTC (Diagnostic Trouble Codes) memored, unlock and reset the Airbag ECU. Then the Airbag light will turn OFF after approx. 4 seconds, ignition ON.
Good Luck!

Have you checked for codes ? Might be your first place to begin checking on what is causing your air bag light to stay on.

disconnecting the power will cause the airbag warning light came on as a warning that you may have a faulty unit,can be reset if you have the machine to do it(your local dealer will have one)The radio will require you to put in the code to restart it....

you cant turn it off, if the light is on, that means there is a problem with the airbag system and must be repaired.

my advise to you is not to attempt a repair to the airbag system yourself. The airbag module can be set off by static electricty & goes off with the force of a shotgun blast

i had this problem a few years ago,, i had to have the wiring loom replaced from the door section. i was told that there was probably a loose or cracked wire in the loom. after that i never had a problem

Since my last post, I found a bright yellow connector under the drivers seat. I took the connector off of the end, bent it a little, and put it back on. My air bag light has stayed off. I am going to put some electrical grease on it and see what happens.
