20 1 1 Audi q7 has been engaged in the S gear and the speed suddenly jumped to 5.

What you want to ask is the reason why the speed of 20 1 1 Audi q7 suddenly jumps to 5 in the S gear? Oil is inferior. According to the query of Pacific Auto Network, poor engine oil and poor fuel used by vehicles will make the fuel in the engine cylinder unable to fully burn with air, resulting in abnormal engine, which will lead to high-speed driving of vehicles and failure of throttle assembly. When the throttle opening is large, the vehicle speed will become higher. Audi Q7 is a medium and large luxury SUV car produced by Audi in Germany, which made its debut at Frankfurt Motor Show in 2005.
