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.

It's quite troublesome when the urea doesn't burn during long-distance driving, so I often troubleshoot it myself. First, check if the urea tank is empty and top it up if necessary. Then, see if the nozzle is clogged and try spraying some cleaner. If the dashboard warning light comes on, inspect the wiring for looseness or aging leaks—replacing a new sensor isn't difficult. The key is using the right tools, like a multimeter to check if the voltage is stable. For prevention, a simple system cleaning every 5,000 kilometers can save a lot on repair costs and also protect the environment.

Safety is crucial. Not burning urea will cause excessive emissions, reduce the car's power, and damage the engine. When I encounter this, I pull over, turn off the engine, check the fluid level, and top it up immediately if it's low. Otherwise, continuing to drive can lead to serious issues. Prolonged neglect can damage the catalytic converter, resulting in expensive and hazardous repairs.

It is recommended to visit a professional repair shop for urea system issues. They have diagnostic computers to accurately identify the problem, such as control unit malfunctions or software needing updates. Last time I went for a check-up, it cost a bit but solved the problem once and for all, ensuring safe and stable driving. Don't skimp on these small maintenance costs in the long run.

To save costs, I focus on daily habits: regularly adding urea and choosing high-quality products to avoid impurities; keeping the system clean by cleaning the nozzles every three months; checking for smooth operation before driving. This helps extend part lifespan and prevents sudden breakdowns from causing delays.
