First of all, what is AdBlue? It is diesel exhaust treatment liquid, also known as automobile environmental urea, is made of water and urea, can effectively reduce the content of nitrogen and oxygen compounds in automobile exhaust, it reacts with the NOx from the exhaust gases, turning NOx into Water and Nitrogen. The AdBlue light of your car will be on, when the tank is almost empty, and remind you that you need to top up the AdBlue tank.

  So the owner asked, AdBlue light is on does not matter? According to industry, if the car runs out of AdBlue, the car may does not start, and it is strongly recommended not to let it run out, as it will need to be repaired in the factory. Usually, AdBlue is sold at gas stations. The filling port is near the filling port of gasoline and needs a wrench to open it. Note that when adding AdBlue to the car, do not let AdBlue going into the eyes, if splashed into the hand, remember to use clean water.

  In fact, not all diesel vehicles need to add AdBlue, only the use of vehicle selective catalytic reduction exhaust post-treatment technology (SCR) of diesel vehicles do. Why use this technology? That is because it is required on many European and American diesel vehicles due to increasingly stringent emissions regulations.
