What causes the abnormal noise when turning the steering wheel on Golf 6?

[Muhammad]

Golf 6 makes abnormal noise when turning the steering wheel for the following reasons: 1. Noise when turning the steering wheel while parked: This is likely due to the friction between the horn wire transmission spring steel plate and the steering wheel. The sound usually comes from inside the car and is a rustling metal friction noise. The solution is to apply some lubricant at the friction point between the spring steel plate and the steering wheel. 2. Noise when turning the steering wheel while driving: The sound usually comes from the front suspension outside the car. If it's a sharp noise, it is probably caused by excessive or insufficient front wheel toe-in, leading to tire scrubbing due to non-parallel steering when turning. If it's a dull sound, it is likely due to excessive wear of the car's half-shaft CV joint causing the abnormal noise.
