2014 Volkswagen Passat fuel system problems

Hi , My 2014 Passat driven by a family member struck a parked truck. Luckily, nobody was hurt! The parked car was not occupied and the driver of the Passat was able to exit the vehicle unharmed. The speed was about 35 mph and the air bags deployed. This front collision resulted in a major fire that totally destroyed the car. The insurance company (Progressive) is currently in the possession of the car.

Miles on car at failure: 21,755 corrective actions from dealership: replaced turbo, gaskets, reflash, check particulate filter and replace. Outside air temps at failure:20s 30s failure warning signs, if any: turbo began making horrible whining sound on sunday afternoon march 8, 2015. Called VW 3/9/15 and took to dealer 3/10/15 for emergency appointment prior to 3/12/15 first available appointment. No warning lights or indicators even after 3 days of driving with horrible noise.
