One problem related to air bag has been reported for the 2006 Volkswagen GTI. The most recently reported issues are listed below.
In four years of ownership, my 2006 vw Gti mark v car has had six occasions whereby the airbag fault light has come on. Each time the vehicle was serviced and the light stayed off for a period of months before returning. Most recently, my vehicle was repaired for this reason in December and the airbag fault light stayed off until this week. I have brought this matter to the attention of my dealer and am awaiting guidance on how to proceed. Although the car just went off warranty, I am requesting that vw make repairs at its expense since this problem has been a repeated problem throughout my ownership of the car.
