Video tutorial

In this video we can see how to clean the nozzle that injects the AdBlue additive, by ourselves and without using special equipment or expensive additives. In this specific case it is a Mercedes GLC, but apart from the different location of the nozzle in our car, the system is absolutely the same for any brand or model.

So let's locate the nozzle inside our car and get a bowl with very hot water. Ideally, we should heat it with a tea kettle, so that it is at least 80 °C. We immerse the nozzle inside for a few minutes, and when we remove it we will be surprised to see that it will be clean as when it was new.
