How far can you drive with the urea warning light on?
1 Answers
When the light comes on, it indicates that the backup fuel supply has been activated, which is estimated to be around 7-8 liters. Driving up to 50 kilometers is considered quite safe, but it's best to refuel as soon as possible. Automotive Urea: Automotive urea is a diesel exhaust fluid used in SCR (Selective Catalytic Reduction) technology to reduce nitrogen oxides in diesel vehicle emissions. If the automotive urea is depleted or the SCR system malfunctions, the vehicle may exhibit symptoms such as sluggish acceleration, unresponsiveness to throttle input, insufficient power, and inability to increase engine RPM. Solution: Replace the urea pump and power supply module connector. After replacement, the urea fault code can be cleared upon re-inspection, except for sensor power supply 3, which cannot be cleared. Analysis suggests that sensor power supply 3 refers to the internal power supply module of the ECU. Replacing the rail pressure sensor resolves the fault.
