Hello guys! Got some problems with my 2.0 TDI 170hp, it sometimes has no power, especially after I start it. If I press and depress the accelerator pedal several times, it usually gets to have some power, but far from all of it. The only way which seems to get it to normal is to leave the car idle for 10-15 minutes or drive it at about 1000-1200 rpm for a few miles. Then it's good, it pulls like crazy. I got new fuel filter and new turbo. The car throws no codes, no check engine or other lights, it just stalls. I would like to replace the N75 valve too, just to be sure, but I can't find it. Does anyone know where it's located on this engine? And maybe could someone help with an OEM part code?
