During the fall of 2014, the company received field reports of fuel smell and leaking fuel lines. An investigation found that a supplier had manually reworked a sealing cap on the fuel rail, but with insufficient solder. Consequently, the solder joint can eventually fail and begin to leak.
The problem can be identified via fuel smell or a warning light if the if the fuel-rail pressure cannot be maintained.
VW warns that leaking fuel can result in a fire if it is in the presence of an ignition source, however no accidents or injuries have been blamed on the problem.
The defect affects the 2014-2015 Beetle, Jetta and Passat, along with the 2015 Golf and GTI, for a grand total of nearly 38,000 vehicles. Service technicians will inspect each vehicle and replace the fuel rail if necessary.
