My air bag warning light on the dash is flashing whilst i am driving what should i check?

the buzzer may just be a reminder to make you look at the dash to see that warning light.
You may need to get the dealer to have a look at it.
Sorry that isn't a solution, but something is better than nothing.

Read your owners manual about the light
& why it would come on
No owners manual have a repair shop check it out

Battery went flat on my bmw e46 saloon 05 no power to my dash board cluster turn the key no lights on at all .the only one is air bag

Hello, welcome to FIxYa. Please allow me to assist you.

First, we need to know why the air bag light is on. This can be from a variety of reasons. Some are expensive, some are not. I would first suggest taking the car to a place that can read the air-bag computer, and get the code or codes that are stored determined. The codes are what turns on the light, and leads us through the diagnosis. Without the codes, it is rather difficult to address the cost issues that would be involved.

To answer the second part of your question...the air bag may not deploy in the event of an accident if the light is illuminated on the dash.

Finally, no, the bag will not deploy whilst driving.

Please get the codes read, and get back to us, so that we may be better able to assist you.

Thanks for choosing FixYa for assistance today.

it means the air bags are inoperative, maybe a fuse or an open circuit, best to have someone with electrical knowledge look at it

when air bag flashes that is a warning telling you something is wrong .Meaning air bag will not deploy if you are in a car crash .

have you plugged the air bag wires back in under the seat?
if you have put after market of non genuine seats in you will not be able to turn light off
you could remove the bulb from the dash or just leave it (it will not affect the mot)

Check and see if your alternator is charging
Low voltage will cause those lights to come on, as the computer is shutting down.

To check your alternator you will need a volt meter... WITH the engine running you should have about 14 volts coming out. IF NOT you need to replace the Alternator!

kenchyke, the shop may have disabled the air bag system to work on the car, and possibly forgot to activate it again. While this seems a bit odd to me that they could overlook this but, since it started after the work was done, you need to return it to the shop asap to have them check it out. Although the car runs fine, the abs system and the air bags won't operate, which could result in injury if you are in an accident (air bag will not deploy, abs probably disconnected).
