What is the reason for the acceleration jitter of Audi A6L?

If the Audi A6L is accelerating, the engine will shake normally, which will be very severe. It may be that the throttle is too dirty, and there is too much carbon deposited in the injector and intake. In cold conditions, carbon deposits will absorb some fuel. If the fuel does not completely enter the cylinder for combustion, it will cause the symptoms of unstable idle speed and difficult start.

If the acceleration jitter of the car is obvious, you can first visually check whether the balance lead block on the rim is missing or whether the hub is obviously deformed. If the above places are all right, we will turn to professional testing equipment, because we can't tell the subtle deformation of steering rod, suspension and hub with our eyes.

When the vehicle accelerates rapidly, the engine gearbox assembly should do a slight rollover action, thus changing the position of the above-mentioned stress point. Because there is a certain included angle between the axial direction of the semi-axle and the axial direction of the inner cage, during the rotation of the cage, this stress point constantly changes back and forth along the axial direction, and the force generated by this change constantly pushes the car body to the left and right sides, that is, the feeling of a clever shell appears, and the damaged inner cage or semi-axle is replaced.

It is no small matter to speed up the car. Please go to the maintenance point as soon as possible for inspection and maintenance.
