Last month, the V90 in our fleet triggered the exhaust warning light again, which really gave me a headache. After spending half a day at the 4S shop, they found out that the urea nozzle in the after-treatment system was clogged. The mechanic said this model is particularly prone to crystallization and blockage when using low-quality urea. They replaced the nozzle and performed a computer reset before the issue was finally resolved. I heard that the manufacturer upgraded the exhaust treatment program at the end of last year, fixing the old problem of false alarms in low-temperature conditions. I suggest you check if your vehicle’s system is up to date. If that doesn’t help, test the exhaust treatment line pressure—the high-pressure fuel pump could also be causing trouble. Don’t just clear the fault code to brush it off; dragging this issue out can seriously damage the car.
Last time on a long-distance drive, the exhaust warning light turned yellow, which scared me into pulling over immediately. Later, the inspection revealed that the wiring of the exhaust temperature sensor connector had been chewed through by a rat. This type of sensor is positioned quite low, making it particularly vulnerable. The mechanic mentioned that the DPF regeneration system of the Maxus V90 is quite sensitive and requires the use of China VI standard diesel. Using substandard fuel from small gas stations for an extended period can trigger the warning light. Additionally, carbon buildup on the oxygen sensor and turbocharger air leaks are common causes. Nowadays, 4S shops are quite experienced at replacing these sensors. It's recommended to regularly check the exhaust bellows for cracks, as this is a common issue.
