2009 Volkswagen GTI engine problems

While traveling at 55 MPH in sixth gear on the new york state thruway, I suddenly lost power and the engine abruptly turned off. I consequently quickly decelerated and was almost rearended before being able to turn onto the shoulder. I smelled a burning odor and got out of my car. Eventually, the VW dealership advised me that the #2 coil had failed and caught fire. Consequently, the wiring harness for the ignition coil and plastic cover surrounding the coil had been destroyed by the fire.

Vehicle has 140,455 miles on it and was well maintained. At approximately 15 MPH heard loud sound and had total engine failure. Car was towed to a volkswagen specialist and said that the timing chain threw due to the timing chain tensioner, a common problem for the 2.0 tsi engines from 2008-2012. Minimum for repair would be $4,000 due to bent valves; maximum will be engine replacement (~$9,000). Given car's age and value, neither options are worth fixing and I will have to sell car for parts.
