How to deal with Peugeot 307 emission alarm?

This is one of the standard phenomena of 307, with high emission requirements (Euro IV emission). Seeing that your mileage is very small, it should be caused by frequent low-speed and high-grade driving (or more traffic in urban areas). Just drive to 4S to clean the throttle. If the car is over 2 years old, you can use fuel additives (the kind sold at gas stations). I am this car myself. After using the additive, the medicine will cure the disease, but if you are a new car, it is not recommended to add it. In addition, you can also go to 4S to upgrade 307 (the so-called upgrade of this project is nothing more than changing the emission of 307 from Euro 4 to Euro 3 with software, which may actually lower the emission standard). As for whether to add 97 or not, depending on your spending power, personally, there is little difference, really. Mine is a small mouth 307. Have more time to communicate! Also, don't add gasoline containing ethanol. Many of them are in Henan province. You'll know when you add it. It's called shaking! ! !
