AdBlue issues are extremely common on the Mercedes C-Class (W205) models. You will usually get an error message on the dashboard that reads ENG. START NOT POSSIBLE IN 150 MILES. This message usually clears once you fill the AdBlue tank. However, sometimes it does not, and this usually indicates an issue with the AdBlue system. Once this countdown runs out, you will not be able to start the car.
