November 2014 incidents: two incidents of failing to start. First incident: car failed to start once and started on second try. Second incident: car several times failed to start & engine made clanking noise. Had car towed to vw agency. Car started after unloaded from tow truck and agency found nothing wrong. December 2014 incident: car started, but after slowly driving to parking lot exit and before at full stop, at engine quit and would not restart. I put the car in neutral and backed down a slight grade to get car out of traffic; after coming to a stop the car started up.
Was driving and heard a clicking sound, shortly after my steering and brakes locked up, and then the entire car stalled. I was unable to restart the engine. Had car towed into the vw dealership where they told me my fuel (diesel for Jetta tdi) was contaminated causing the fuel pump to burst which lead to metal shards destroying the entire fuel system. However, I am 100% positive, and have receipts for proof, that the car had been filled up with diesel gas about 1 week prior to the incident and was running completely smoothly up until the sudden break down.
