Driver side air bag and ignitor replaced at my expense in august 2015. i live in glen st. mary, florida. the computer showed failure of air bag on dash board. i have dealer records of repair. this was not a function of an accident.
According to audi atlanta the high pressure fuel pump (hpfp) exploded. this small but contained explosion was centered within the high pressure fuel pump itself but then sent small metal fragments thorough the fuel system from diesel fuel tank through the injectors. due to this 10k+ in parts and 4k+ in labor was required to flush the system, replace almost all of the parts in order to repair the damage.
