Hello together, I drive a Vivaro 2.0 CDTI from 2011 with approx. 175tkm. Last winter the sporadically had the error message “injection check” in the dashboard. This has disappeared after a few minutes, until then on the highway at the beginning of this year “injection defective” lighted up with the STOP symbol. Then the DPF was expanded and burned free in the oven, as it was apparently full. The workshop said then that the oil sensor also indicated that the oil covered until a few weeks ago, everything was fine with the car. Now the error message “check injection” came back. Overall, this now showed up 3 times, the first time only a few seconds, yesterday it stayed several minutes. Today the car then went to the workshop, and from there I just learned that no error was stored, which indicates the DPF. Only oil worn and a fault in the brake light. 2 months ago (approx. 2-3tkm) I had an oil change done without a reset or deletion of the error (if this one was already there). I can’t rhyme on it, and that the workshop can’t either frustrates me a bit, because I don’t want to have the DPF cleaned every winter. A few years ago he has problems with the glow candles, then I changed a few. The error was then gone. If it was very cold, I had to change it. is (below 0°C) sometimes the engine control light and the service light light light shine briefly when starting, so I think there could still be a problem with the glow plugs. But nothing seems to appear in the error memory. The car always went normal, and also did not go into the emergency run when the error “injection defective” appeared. Something seems to prevent the regeneration of the DPF at cold temperatures. Do you have any idea what that could be?
