What are the drawbacks of disabling urea injection in China V vehicles?
2 Answers
China V vehicles disabling urea injection have the following drawbacks: For the vehicle itself: China V vehicles must use urea; failure to do so may result in torque limitation, poor acceleration, lack of power, and increased fuel consumption. Environmental protection: The government has introduced new environmental policies focusing on diesel vehicle exhaust treatment. Urea is a mandatory additive to process nitrogen oxides in exhaust gases, reducing harmful emissions into the atmosphere. Therefore, not using urea will cause air pollution. Traffic enforcement: Many regions now have exhaust emission testing points, similar to speed detection. If exhaust emissions exceed standards and are detected, the vehicle will be penalized.
My cousin did this a couple of days ago and ended up in big trouble. The most critical issue with disabling urea injection in China V vehicles is the excessive exhaust emissions—it won't pass inspection, and you'll constantly smell a pungent odor. Over time, the exhaust system will definitely fail, with the catalytic converter getting severely clogged. With over a decade in auto repair, I've seen several owners secretly disable urea injection, only to end up spending thousands later to replace the entire exhaust system. Saving a bit on urea costs really isn't worth it. Plus, roadside inspections are strict now—last time, I saw someone fined 2,000 RMB. Long-term urea omission triggers vehicle speed limits, and suddenly losing power on the highway is terrifying. Honestly, just keep adding urea for peace of mind.
