Can the car still run if the urea pump is broken?
1 Answers
Yes, it can. Urea is a liquid used in SCR (Selective Catalytic Reduction) technology to reduce nitrogen oxide pollution in diesel vehicle exhaust. This urea consists of 67.5% deionized water and 32.5% high-purity urea. Without urea, it needs to be replenished promptly. Here is some extended information: The function of automotive urea solution is to convert nitrogen oxides in vehicle exhaust into harmless nitrogen and water, primarily to make vehicles energy-efficient and environmentally friendly, enabling them to meet national emission standards. Therefore, if the urea pump is broken, the exhaust gas content in the tailpipe will increase, polluting the environment, and it should be addressed promptly. When the urea pump fails, the vehicle will directly trigger an SCR fault alarm.
