Hello! I have an Audi a3 1.6 tdi 2010, 93k km. Engine light is on, code p040100. I have change EGR with a new one an clean all the pipes. But i have again same problem. It knock the engine a little when i start around 2-3 min like a misfire and after disaper. When engine is 90 degree works perfect. But sometime in IDLE it shakes. Something else is showing me code P04100 but i can't find it. Kind of sensor or something else. Thank you!
