start engine

[claudiuw205]

I have a 2015 Mercedes-Benz W205 diesel and I encountered a problem after changing the fuel filter support and the gasket of the oil cap. Now, in the morning, when the engine is cold, the car starts with difficulty and stops after a few seconds, but if you put the key in the ignition three times and then try to start it, it starts normally. I went to the dealership and they found no errors on the diagnostic, and the injection correction values are fine. Does anyone know what the problem could be?

Low fuel pressure and/or air in the diesel.

Always worth checking the battery voltage/condition.
