Having difficulty with my VW Jetta sportwagen 2012 with its high pressure fuel pump having contaminated the fuel system in the car with metal shards captured on the fuel metering valve. Entire fuel system needs replacement. The car is a certfified pre-owned and only 11 months into a 2-year bumper-to-bumper warranty. The dealership, regional case dispute manager, and technical dispute inquiry have all come back and reported that it is an externally created issue from the diesel fuel I put into the tank. However, this is a well-documented ongoing issue with VW diesel engines with their high pressure fuel pumps dating back to 2009. The fuel I put into the car was tested and came back entirely fine. And by virtue of the metal shards being found on the fuel metering valve that is wholly indicative of the contamination being cause after the fuel has gone through the high pressure fuel pump, to the engine, and the excess is returning back to the fuel tank via the fuel metering valve. I was told that the metal shards were only found on the mesh piece/filter on the fuel metering valve not on the fuel tank filter itself (which you would think there would be metal shards on the fuel tank filter if the diesel that I put into the car was the original issue). The car has no acceleration after approximately 40 mph, and further driving of it will just further compromise the fuel system. The problem occurs very suddenly without warning, as it did in my case, which doesn't allow for correcting before it's much too late. I'm facing an estimated $5500 repair but that is on the low side of what has been reported by others that have faced the same situation. My car is under warranty, this has been an ongoing issue since 2009 with VW diesel high fuel pumps, I believe they should fix under the warranty as they know this is an internal equipment/parts failure.
