2012 Volkswagen Passat engine problems

I was driving down the street and heard a loud pop like a tire blew or belt broke or something, then I saw a lot of smoke, so I pulled in a party store parking lot and it was engulfed in flames burnt the entire engine up to a crisp. I have video and pictures of this traumatic event. So please investigate to see if this is a manufacture defect. I need another car as soon as possible. Thanks. The car has been towed to vyletel volkswagen dealership in sterling heights, michigan.

On my 2012 tdi when the weather gets cold ~ below 10 degrees fahrenheit the engine feels like it is misfiring. It usually starts fine, but it stumbles/misfired for the first mile or so. The car does not want to get up to speed, nor will it shift into the next gear, the engine will rev to 3000 RPM and more when cold, which is very bad for the engine. I will manually shift into the next gear and then it chugs and misfires and struggles to get up to speed.
