The emissions system warning light on the Opel Astra is the AdBlue warning light. This additive is necessary for all diesel engines used from 2016 onwards. Once it is illuminated, how can you reset this light? It is important to know that there is no manual reset system for the light. To turn it off, you simply need to refill this additive, and the video provides instructions for this operation. Just open the cap of the designated tank and pour the liquid inside. The light will automatically turn off immediately or, in most cases, after driving a few miles.
