Fuel Hoses Lines/piping And Fittings problems of the 2010 Volkswagen Jetta Sportwagen

2010 jetta wagon tdi (35,500 miles); wouldn't start in am before work. Would crank but not turn over. Had it towed to dealership. Said "fuel was contaminated" and that the tech saw specks of something throughout the fuel system. They tried the line on me of "you must have mixed it with gas". I bought a diesel b/c I wanted to drive a diesel. I didn't mix them up. Not to mention I had already drove through half a tank of fuel before this incident. Vw agreed to warranty the repair however at $7500. What happens next time? am I out $8k? I have the top tier "platinum" warranty but will it be covered for "contamination?" my vw service dept couldn't (or wouldn't) tell me anything. I called vwof America customer service line to have a case opened or get any information. I was called back in 24hrs by a woman that said, "it's not vw's fault you need to call the gas station b/c it was contaminated fuel". I find it odd that vw is covering the cost yet it's "not their fault". What company honors a warranty when they are not responsible for the damage? so where does that leave tdi owners? are we supposed to carry around a chemistry set and test the fuel before we fill up? if I want to take a trip with my car I guess I can't now b/c I may not be able to find a "brand name" like shell or exxon. I think I have to sell the car. Kbb trade-in is $20,000. I wonder what vw will offer me on a trade of my tdi. . . . . . My car is still in the shop a week later, I have a loaner, I'm terrified to pick up the car and tomorrow it doesn't start again.

Noticed diesel leakage around the second valve of my tdi engine. None of the other valves on the 4 cylinder engine demonstrated leakage. No cracking of the fuel lines.
