What is the solution for not consuming urea?

The solution for not consuming urea is: 1. Check whether the post-processing wiring harness and sensors are in normal contact, and make timely adjustments and repairs if there are any issues; 2. Check whether the urea pipeline is normal and whether there is any leakage. If there is, it needs to be replaced in time; 3. Check whether the urea pump is working normally. Once abnormal operation is found, the cause of the fault needs to be checked in time; 4. Check whether the urea nozzle is working normally. If the nozzle is found to be clogged or cannot open normally, it should be cleaned or replaced in time. Automotive urea, also called exhaust treatment fluid, is a liquid used in SCR technology to reduce nitrogen oxide pollution in diesel vehicle exhaust. If the vehicle does not consume urea, it means the SCR system is not working properly. Although it can save money on urea, the chemicals inside will quickly oxidize, and the urea nozzle will also become clogged, causing the entire system to be scrapped.
Recently, my diesel car also encountered the issue of urea not being consumed, which is usually caused by the urea level being too low. Refilling it should solve the problem. If the issue persists after refilling, it might be due to a clogged nozzle—cleaning the pipeline usually helps. Alternatively, the sensor might be faulty, displaying incorrect data, which requires a reset. In winter, low temperatures can cause urea to crystallize, affecting its flow, and preheating the car can alleviate this. Prolonged lack of maintenance can trigger system alerts and increase fuel consumption, so I've developed a habit of checking the urea level monthly and using reputable brand urea to avoid impurities. If you notice any issues while driving, don't push it—address them promptly to prevent damage to the vehicle.
