If you need to reset the blue warning light that illuminates on the dashboard and remains on even after topping up the additive, you can use a diagnostic system that you can download to your PC and then connect to the OBD2 socket located on the vehicle's dashboard.

This procedure is valid for the Skoda and is applicable to most types of cars.

After connecting the diagnostic socket to the PC, select the type of vehicle, then make and model, wait for the connection and data download from the ECU, select "engine" and then select "reset AdBlue", press OK and wait for the data transfer. At that point, the AdBlue warning light on the dashboard will turn off.
