How to Reset the Urea Solution Warning Light?
2 Answers
1. Vehicle lacks power with normal urea consumption: If the vehicle lacks power but urea consumption is normal, and a small amount of white smoke is observed coming out of the muffler when accelerating sharply, replacing the urea solution should resolve the issue. 2. Low urea pressure with high urea consumption: If the dashboard warning light frequently flashes, indicating low urea pressure and high urea consumption, replacing the water heating valve will fix the problem. 3. Insufficient power with abnormally high or low urea consumption: If the warning light stays on constantly, the vehicle lacks power, and torque is limited to 1800 RPM, indicating the SCR system is not functioning properly with either excessively high or low urea consumption, replacing the urea pump and power supply module connector is necessary.
Last time my urea solution warning light came on, it was really scary. I pulled over, popped the hood, and checked the urea tank - sure enough, it was empty. I bought a bottle of AdBlue and topped it up, and the light went off after a few minutes. But if the light stays on, it might mean a faulty sensor or system issue, requiring a diagnostic tool reset at the repair shop. I recommend keeping a jug of urea solution in your vehicle and checking levels regularly, especially since urea depletes quickly during driving, particularly on long trips. I've found that using high-quality urea reduces warning frequency and prevents nozzle clogging or contamination issues. Don't forget to check your dashboard messages - sometimes it's just a simple refill reminder you can handle yourself.
