Reasons for Audi Steering System Malfunctions?
2 Answers
Audi a6l steering system malfunctions and their solutions are as follows: 1. Abnormal noise during steering: The cause of abnormal noise during car steering is generally due to damage to the kingpin and bushing, or damage to the column thrust bearing. When encountering this situation, you can turn the steering wheel left and right and disassemble and inspect based on the location of the noise. 2. Steering gear oil leakage: Oil leakage in the steering gear usually occurs at three places: the upper cover of the steering gear, the connection between the steering shaft and the arm, and the side end cover. This is often caused by prolonged use of the car leading to sealing issues. Since these three parts have sealing rings, replacing the oil seal and sealing rings can solve the problem. However, if oil leakage occurs in other parts, it may be due to sand holes or cracks in the steering gear housing. Small gaps can be sealed with high-permeability sealant, while larger gaps require replacement of the corresponding parts.
After driving an Audi for many years, I've found that steering issues are often related to the power steering system. Particularly in older models with hydraulic systems, steering becomes heavy as a rock when the power steering pump leaks or the belt loosens. Common problems in newer electric power steering models involve sensor failures, such as a malfunctioning steering angle sensor causing system misjudgment and intermittent power assistance. The control module is another small but critical component prone to overheating and burning out, especially during hot weather or after long drives. Wiring issues are also troublesome—corroded wires or loose connections can lead to intermittent signals, causing the system to fail. I recommend first checking the power steering fluid level and belt tension yourself. If those are fine, use a mobile app with an OBD scanner to read trouble codes. A weak battery can also affect power supply, as both the power steering and electronic devices rely on it. If the steering becomes heavy or a warning light comes on, don't delay—head to a professional repair shop immediately, as safety is far more important than saving a few bucks. Routine maintenance, like checking steering components during oil changes, can prevent problems before they occur, especially since steering failure at high speeds is terrifying.
