Recently reported ENGINE problems on 2012 Audi A6

Upon starting my vehicle i noticed extended cranking. upon driving the vehicle i noticed a fuel odor, initially i thought it was the older vehicle driving in front of me. after driving approximately 4 miles i realized it was my vehicle. i then drove my vehicle back to my house, and had it towed to audi of albany due to recalls that were open. upon inspection they performed recalls, but informed me the recall for the engine fuel rails was performed june 2015. they then told me they needed to charge labor to inspect the issue, to which point i told them i am an ase master mechanic, and i will figure the issue out myself. i then had the vehicle towed to my garage, where i took it apart following the recall provided on your website. upon inspection i verified that the injector supports (p/n 06d133036k) listed in the recall (code 24ap) were never replaced. the injector supports i removed from my vehicle are (p/n 06d133036h). audi has had my vehicle now from 21nov2018 until the present. they will not verify that those parts were supposed to be replaced during the recall, and also if any other parts were never replaced. they have contacted me and told me my fuel injector failed causing the fuel leak, and everything will be covered. i believe my injector failed (if that is the truth) due to the non replaced injector supports. the incorrect geometry over time would cause stress on the injector, and for it to crack. i also question if any seals were truthfully replaced, or if the recall was done at all. i also fear that this issue may have occurred to others who had the recall performed there (langan audi), and are not mechanically inclined enough to disassemble there engine and fuel systems. this problem could have caused a fiery death for me and my family in the car if i wasn't inclined enough to realize the problem is my car and not others around me.
