The owner of this 2018 Audi 2.0 TDI requested help after an AdBlue/SCR warning appeared on the dashboard. The countdown to a starting restriction showed approximately 900 km remaining. Diagnostics indicated a pressure issue in the AdBlue system which, according to the video, could be related to the pump near the tank.

The EDC17C74 control unit was removed and read on the bench with Flex. After software changes, the ECU was refitted. When the ignition was switched on and the engine was started, the AdBlue warning was no longer displayed.

The video does not show a pump repair or replacement of AdBlue system components. The confirmed result is therefore limited to the warning disappearing and the vehicle starting immediately after the software work; long-term system operation was not demonstrated.
