This 2018 Renault Trafic with a 1.6-litre diesel engine arrived with an AdBlue/SCR warning and less than 160 km remaining on the vehicle's countdown. The driver reported that the engine might no longer start when the countdown ended. No stored fault codes were found during the diagnostic check.

After inspecting the vehicle, changes were made to the engine control unit software related to the SCR system. Following an ignition restart, the warning indicators were no longer lit, and the engine could be started and revved.

The DPF remained fitted to the vehicle. A diagnostic tool was used to command a regeneration, and the system began the process. The video does not confirm that the regeneration cycle was completed, so completion is not presented as a verified result.
