2009>Jetta, Golf, Touareg with Common Rail TDI Engine - Fuel System Diagnosis Tip
It is not recommended to pinch off the fuel return line at any time during the diagnosis of the fuel system on the common rail diesel engines. This will create excessive pressure on the piezo crystals of the injector solenoid and could cause damage to the injectors.
