How about the mobile car control system of Niuren Technology? Have you ever installed a friend?

My Chevrolet has run more than 30,000 kilometers in three years. A few days ago, the engine trouble light suddenly turned on, but people and cars were out of town, so I couldn't go to the 4S shop for maintenance. I happened to be using this product of Niuren, and found the fault code after the mobile phone test. It is said that the oxygen sensor on my back is broken, so I don't need to find a manufacturer to repair it for the time being. After returning to the 4S shop, I felt uncomfortable. It has been tested by more than 370 computers, and it is found that the rear oxygen sensor is really broken, and there is a fuel consumption reminder function to detect the car condition at any time and protect the car safety. Therefore, the mobile phone control of Niuren is still very recommended.
