Good day together, I have a problem for a long time. After about 5 hours of real driving time I get the error message injection check. When I read the then the errors df028 and df010 come to light. From about a year all valves and high pressure pump were replaced. The error comes for a few months. During the ride you do not notice any unusual behavior and after the deletion the error is gone. Funny way it seems to be no matter how long I drive but the mistake seems to come back after a certain time. Does anyone have an idea what I can do? Do not want to pump more money into the car. I attach pictures. Thank you and greeting Antonio
