I have an Audi A6, 01, my alternator died on my 3 month ago, i had almost all my warning lights on, then i changed the alternator, now the only light that is on is the Airbag light, and i just cant figure out the problem, any idea what the problem might be? woul appreciate any help!

 

If the airbag light is on there is probably a problem with the air bag. Has nothing to do with the alternator.
You have to get the fault codes read, one possiblity is if you have a child seat in the back, when the seat back isn't fully latched it will trip the airbag light.

 

diagnostics sayed (Driver seat airbag igniter 1) that was it, the mechanic told me that my airbag may not inflate when i crash or anything, he tried clearing it, but it didnt go away, very annoying, any idea if i can try anything to help the situation?

 

Nothing you can do, the airbags are designed to last about 10 years.
If you don't want to replace the air bag you can solder in a resistor in the air bag harness to turn off the light.

 

i want to replace the airbag, my warranty is out, so what should i do? i dont think a regular mechanic can change it, the audi dealers arent the best people when it comes to a reasnoble price!
any ideas?

 

The airbag is easy as hell to replace you just have to be careful with the old air bag (as it is always armed) Buy the airbag from the dealer (not cheap) then locate the two T30 torx bolts on the back of the steering wheel, rotate the bolts out until they won't come out any more (they don't release from the wheel) then the airbag should fall off the steering wheel, dis-connect the harness and place the bag aside with the dangerous end pointing upwards (the other way will turn it into a rocket if it went off)
Clip the new air bag in and bolt it down, put the old bag into the box you got the new one in and take it back to the dealer for a core charge.

 

thank you for your fast reply, i will give it a try and update how it went
