How to Eliminate the Urea Warning Light?

[Young]

Urea warning light can be eliminated by the following methods: 1. If the vehicle exhibits symptoms such as poor acceleration or white smoke from the exhaust pipe, professional equipment should be used to clean the urea crystallization inside the exhaust pipe; 2. If the vehicle fault code indicates low urea pressure, urea should be replenished; 3. If the engine torque is limited and the speed cannot exceed 1800 rpm, the urea pump and sensor should be replaced. Automotive urea is a diesel exhaust fluid that uses SCR (Selective Catalytic Reduction) technology to reduce nitrogen oxides in diesel vehicle emissions. If the automotive urea is insufficient or the SCR system malfunctions, the vehicle may show symptoms such as poor acceleration, unresponsiveness to throttle input, insufficient power, and inability to increase engine speed.
