Hi there,
My Yeti 2.0L 140HP TDI engine brings a glow plug MIL and reduces power. However the car runs extremely smooth and therefore cannot even suspect the fuel pump. The authorized center even replaced the dreaded fuel pressure relief valve at the common rail.
They say there is nothing found at the HPFP including the pressure regulator on the high pressure pump .
Is there any procedure to check anything else other than the fuel pump itself. Or is it cos of the sump pump inside the fuel tank.
