How to Eliminate the Urea Warning Light?

Methods to eliminate the urea warning light: Replace the urea pump and power supply module connector, and after replacement, recheck the urea fault code to clear it. Here is extended information about the urea warning light: 1. The urea solution warning light is a protective measure for the SCR system. The illumination of the urea solution warning light usually indicates a related fault. Possible causes include: depletion of urea solution, substandard quality of urea solution, or blockage in the SCR system pipeline. 2. When the urea solution warning light is on, symptoms may include a constant fault light, insufficient power, torque limitation at 1800 rpm, malfunction of the SCR system, and abnormally high or low urea consumption.
Last time my urea warning light came on, I immediately checked the reason. This light indicates that the vehicle's urea solution is running low or there might be a minor issue with the system. First, I visually inspected the filler port to confirm if the urea level was too low. If so, I purchased a bottle of AdBlue solution and added it. The process is straightforward: open the engine compartment, locate the blue-capped filler port, and pour the solution in slowly to avoid spills. After refilling, start the vehicle and let it run for a few minutes; sometimes the light turns off automatically. However, if it doesn’t go off, it could mean a faulty sensor or a problem with the urea pump. In such cases, don’t delay—visit a 4S shop or service station as soon as possible, because prolonged neglect can affect emissions and engine performance. As a preventive measure, I regularly check the urea level every few thousand kilometers and maintain the system to avoid unexpected warnings on the road. Safety always comes first.
