How to Check the Remaining Urea Level?
3 Answers
There is a blue gauge next to the fuel gauge, which is the urea gauge. You can check the remaining urea level through this gauge. The most basic function of automotive urea solution is to convert nitrogen oxides in vehicle exhaust into harmless nitrogen and water, saving energy and protecting the environment, enabling the vehicle to meet the national exhaust emission standards. The following is an introduction to automotive urea: 1. Origin: Automotive urea solution was first used in Europe and is called AdBlue. In North America, it is known as DEF (Diesel Exhaust Fluid), while in China, it is referred to as automotive urea solution or "automotive denitrification agent." However, it is now generally called "automotive urea" in China. 2. Function: Automotive urea solution is key to reducing pollutant emissions from diesel vehicles. It is a urea-based chemical reactant, composed of high-purity urea and deionized water, forming a 32.5% concentration solution. Applying automotive urea solution in the SCR system is crucial for engine exhaust emissions to meet the National IV and higher emission standards.
When I first learned to drive, I made it a habit to check the urea level. Every day after starting the vehicle, I would keep an eye on the dashboard indicators. My car has a small digital display that clearly shows the urea percentage; when it drops to around 20%, a yellow warning light comes on, reminding me to refill. If ignored, once it falls below 10%, the system may limit the speed or even lock the engine, which once left me embarrassed on the highway. Besides checking the display, I regularly open the hood to inspect the urea filler port—the small blue cap should not be left loose to avoid leaks. I recommend carrying a bucket of urea in the car for long trips, choosing reputable brands to prevent impurities from clogging the system. Proper maintenance not only ensures smooth driving but also helps reduce exhaust pollution, making it more environmentally friendly. After developing this habit, my diesel SUV runs more worry-free.
I love exploring technical details when it comes to cars, and checking the remaining urea level is quite convenient. After starting the vehicle, the dashboard usually displays an icon or menu option showing the urea level; I often use an OBD-II scanner connected to a mobile app to view real-time data, which displays the percentage very accurately. When the warning light comes on, it typically indicates a remaining level between 15% and 20%, and the system will automatically record a fault code. A quick tip: when refilling, avoid using a dirty funnel to prevent crystallization and blockages, ensuring the SCR system functions properly. I regularly monitor temperature changes, as urea tends to evaporate more quickly in extreme weather, requiring more frequent checks. Maintaining the proper level is crucial for extending the vehicle's lifespan and controlling emissions.
