WHILE THE VEHICLE IS TURNED ON BUT STATIONARY (E.G. STOPPED AT A RED LIGHT IN LIGHT TRAFFIC) I BEGAN TO SMELL DIESEL EXHAUST IN THE CABIN OF THE VEHICLE. THE ODOR WAS VERY STRONG AND I HAD TO LOWER THE WINDOWS IN ORDER TO BREATHE. THE MECHANIC INFORMED ME THAT THERE WAS AN OIL LEAK NEAR THE TURBO. I HAD TO REPLACE THE FUEL INJECTOR AND LEAK LINE, IN ADDITION TO ALL PIPE SEALS AT TURBO.
