What does the adblue light mean?
2 Answers
adblue light on means that the owner needs to add diesel exhaust fluid. adblue refers to automotive urea, vehicle urea, or automotive environmental urea, which is generally made of water and urea. It can effectively reduce the nitrogen oxide content in vehicle exhaust and lower air pollution caused by NOx. When the adblue light is on, it indicates that the automotive urea fluid is low and needs to be refilled. More information about the adblue light is as follows: 1. According to industry insiders, if the vehicle runs out of environmental urea, it may fail to start, and it is strongly recommended not to let it run out, as this would require factory repair. 2. Usually, automotive environmental urea is available at gas stations, and the filling port is near the fuel filler, which requires a wrench to open. 3. When refilling automotive urea, be careful not to let the urea get into the eyes. If it splashes on the hands, remember to wash it off with clean water. 4. Automotive urea is a consumable necessary for SCR technology, consisting of 32.5% high-purity urea and 67.5% deionized water.
Last time I was driving, the AdBlue light came on, which gave me a scare. Turns out it was just reminding me to refill the urea solution. AdBlue is a blue liquid used in diesel vehicles' exhaust systems to reduce pollution emissions. The light usually indicates that the fluid level is too low or nearly empty. If ignored, the vehicle might go into limp mode or even fail to start, which is quite dangerous. My habit is to check the tank once a month, and if the level is low, I just buy a bottle of AdBlue at the gas station and pour it into the dedicated filler port—usually a quick and easy task. Additionally, the light could also signal a sensor malfunction or a clogged system. If it stays on after refilling, it’s crucial to get the SCR system checked by a professional immediately. Developing a routine of regular checks can save a lot of hassle and prevent unexpected breakdowns on the road.
