What causes the steering wheel vibration when Audi q7 is idling?

When the Audi q7 is idling, the steering wheel will vibrate, which is generally caused by too high or too low idling speed. Too high or too low, when the engine frequency reaches the vibration point of the car body, the vibration will be transmitted to the car body, and the steering wheel will have obvious vibration feeling. You can check the spark plug and ignition coil of the vehicle engine, and then clean the throttle and injector.

Idle speed is a working state of the car, which means that the engine runs in neutral position. The engine speed at idle speed is called idle speed. You can adjust the idle speed by adjusting the size of the throttle. Idle speed means that the engine output is not working. When the engine is running, if the accelerator pedal is completely released, the engine will idle. When adjusting the idle speed, the speed should not suddenly rise or fall, otherwise it will cause early wear and tear to the engine, so it is best to go to the automobile maintenance department for adjustment.

Idle speed means that the engine runs with no load, and it only needs to overcome the friction resistance of its internal parts and does not output power. The lowest speed to keep the engine running stably is called idle speed, which is one of the five basic working conditions of the engine. A good engine idle speed is generally between 550 and 800 rpm. Idle speed can be adjusted by adjusting throttle opening and idling oil supply. Generally speaking, idle speed is the lowest speed when the engine does not shake in the idle speed range and the acceleration performance is good.
