This 2017 Mercedes-Benz diesel displayed an AdBlue warning and a message that the engine would no longer start after approximately 700 km. Before the work, the technician checked the control units and confirmed an issue related to the AdBlue system.

EDC17CP57 ECU work

The video shows the Bosch EDC17CP57 being read and reprogrammed without opening its casing. The technician says Flex equipment was used. Changes were made to the AdBlue-related ECU software. The video title also claims a power increase, but gives no figure for it.

Checks after programming

The ECU was reinstalled and the vehicle was scanned again. The technician reported that no fault codes remained and that the 700 km countdown message had disappeared from the dashboard. The video does not show a technical inspection result.
