98 porsche airbag n check engine light
 

I have a common problem for 98 Boxster.It hasa blinking airbag light.They offer me to change the both buckles and it will dissapear.Does the airbag work while the light is on?
if I change the battery,does it cause any problem for airbags if the airbag light is on?

I just change my air filter and put a Kn on it.Anyone knows does it effect the check engine light because it pop up just after theair filter changed?
