The video covers two 2018 Audi vehicles with different software issues. On one 3.0-litre diesel, another workshop had changed the AdBlue/SCR software and increased power. After that, cruise control worked intermittently, sometimes engaging and sometimes not.

AutoChip checked and revised the engine control software, then carried out a road test. No fault codes were present after the work; the turbo and fuel-rail pressure readings were considered satisfactory in the logs, and cruise control operated during the test drive. The video does not show a physical repair to the SCR system.

The second Audi, a 2.0-litre diesel, had reached the end of the remaining-distance countdown shown by the AdBlue system and would no longer start. A software check found that the previous calibration had been set up incorrectly, so the control-unit software was corrected. The video does not provide a separate, detailed post-work test for this vehicle.
