Can anyone explain the interpretation and the limit values and, if necessary, the possible reasons for malfunctions? Where do the rail pressure calibration points derive from? Do the control times or the timing belt drive play a role?* My motor starts cleanly, pulls in and through at all speeds, but when I glide along in the partial load, it really starts to twitch fast. ZMS and AGR are excluded, LMM also delivers clean results. Have a screenshot of current values of my 4 injectors attached. Return flow test is currently not available. *Reactively, the partial load trucking could only occur at approx. 90,000km since the tooth belt change, i.e. before 90,000km. already before.
