Other Fuel System Tank Assembly problems of the 2013 Volkswagen Passat

The tdi diesel tank sloshes when accelerating from a stop. The noise is a major nuisance. Are there no baffles in the fuel tank?.

Ad blue reductant tank failed. Thus making the emissions system not work properly. Part # 561-198-970-a is defective. The same failure occurred on my 2012 Passat within less than a month. This is a known defect from vw. Here is a link to a thread on the extent of these failures. . Read more...

Redundant tank heater failure. Very common issue (to the point that there are several "how to" fix it yourself procedures and a "hack" to trick the mil light into thinking it is working. Even though it failed within the carb warranty period, vw refused to fix under carb warranty because a vw dealership did not diagnose it within the warranty period (it was 3rd party mechanic) and car is now well out of carb warranty. It is a very costly repair and an extremely common failure, to the point were there is a vw TSB on the part failing in the Passats and touregs. I have approached vw twice on the issue, but to no love from them. Car is still drivable since this part is not used in the climate that I drive it in, so I have not fixed it for a year and a half now.

While sitting still in a parking lot the vehicle suddenly knocked violently and stopped running. According to the dealer the vehicle experienced a sudden and catastrophic failure of the high pressure fuel system causing metal fragments to be spread through the fuel system. The vehicle had approximately 1/2 tank of fuel and had ran perfect before the incident. At no time have we ever accidentally filled it with gasoline instead of diesel and at no time had the engine ran rough as if it was having trouble combusting the fuel.

Our 2013 Volkswagen Passat leaked gasoline on to our garage floor while sitting in the garage. The garage floor was covered and you could visibly see the fuel dripping from the gas tank. The fumes filled our garage and home and resulted in extensive clean up and ventilation. The Volkswagen dealership arrived with a flat bed and towed the car back to the dealership. The man who towed the car even commented about the odor and you could visibly see the gasoline running from the car as it was loaded on to the flatbed. The Volkswagen dealership says there is nothing wrong and no changes to the vehicle are necessary!.
