Audi A4 steering gear failure reasons are as follows: Heavy steering failure causes: The power steering system contains a large amount of air, leading to abnormal car steering; Foreign objects in the steering hydraulic pipeline cause the steering pump flow control valve to stick; Loose connections in the power steering system result in steering fluid leakage; Excessive wear of the steering gear piston cylinder, poor oil seal sealing, or control valve sticking or damage. Abnormal noise during steering causes: Overloading of the steering system leads to excessive wear of the stator and rotor inside the steering pump, causing irregular movement of the oil in the pump and producing abnormal noise; Loose installation of the steering gear or pump on the bracket, internal wear of the steering gear, and improper adjustment of the gear and rack.
