2006 Audi A6 Quattro Q&A
2006 Audi A6 Quattro Question: Airbag light is on. What does this mean and how to fix it?
The only way to turn off this light is to take it to some one that works on airbag systems. That light is on because of a system malfunction, it could be one of the bags themselves, one of the impact sensors, the computer that controls the whole system. Or the wiring between all of these. - Pvt-Public
I had a similar issue. I brought mine (2006 A6 4.2L s line) to the dealer and they determined it was a faulty airbag sensor in the back seat. The light indicates a fault somewhere in the airbag system. The fault can prevent the airbags from properly deploying in a crash and should be checked and repaired ASAP considering no one ever plans on having an accident nor do they occur when it would be more convenient. - perfect-audi-weather
