How to use X431 for matching after replacing the steering gear on an Audi?

[OliveAnn]

After replacing the steering gear, it is necessary to go to a repair station for professional computer matching, as it cannot be done by the vehicle itself. The relevant introduction is as follows: 1. Steering gear: If an upgrade requires online access, you need to go to a 4S shop. What wheel alignment can solve is the vehicle not deviating during normal driving. If the vehicle does not deviate but the steering wheel is off, then the steering wheel needs to be adjusted. If the steering wheel is still heavy after replacing the steering gear, then the problem lies with the steering gear. 2. Tire alignment: Uneven wear or different air pressure in the left and right tires. Inconsistent positioning parameters of the two front wheels, inaccurate positioning parameters of the rear wheels. Bending or deformation of the left and right steering tie rods, excessive clearance at the hinge. Unequal elasticity or excessive deformation of the two front suspension coil springs. Excessive clearance after wear of the wheel hub bearings. Frame deformation. Deformation of the front or rear axle. Improper adjustment of the axial machine. Single-sided brake drag.
