What Happens When a Vehicle Runs Out of Urea?

[DiLane]

A vehicle can continue to drive without urea, but it is necessary to replenish it promptly. Prolonged operation without urea can cause harm. Urea is a liquid used in SCR technology to reduce nitrogen oxide pollution in diesel vehicle exhaust. Driving a car without urea for an extended period can have the following effects: 1. The urea pump's nozzle and pipes are prone to crystallization blockage or high-temperature damage. 2. The emission light will turn on, torque will be limited, power will be insufficient, and the vehicle will feel very sluggish. 3. For trucks without added urea, not only will they fail the annual inspection, but the driver may also face penalties.
