Why does the Audi A4L make noise when turning the steering wheel?
2 Answers
The following are the reasons why the Audi A4L steering wheel makes noise when turning: Lack of oil in the shock absorber's plane bearing: Listen near the engine hood to see if the sound is coming from the top of the shock absorber. If the noise is from the plane bearing of the shock absorber, you can apply some grease to the plane bearing. If the noise persists after greasing, replacement is the only option. Loose stabilizer bar bushing: Check if the stabilizer bar bushing is loose or damaged. A loose or damaged stabilizer bar bushing will not only cause noise when turning the steering wheel but also when driving on uneven roads. A loose stabilizer bar bushing can be fixed by adding shims, but if it is damaged, it must be replaced.
As a daily driver of an A4L, I hear a creaking sound whenever I turn the steering wheel, which is really unsettling. My car is about three years old, and it might be due to wear and tear on the tie rods or ball joints, or friction from aged rubber—especially more noticeable in winter. Sometimes, uneven tire pressure or excessive tread wear can also cause this, particularly during low-speed turns. Another common issue is with the shock absorbers, especially if the front struts are leaking oil, leading to squeaky noises. I suggest driving slowly on a flat road to pinpoint the source of the sound. If it’s coming from the front right, it’s likely a suspension component. Occasionally, faults in the electric power steering system, like unstable power supply or motor hesitation, can also cause noise. For safety, don’t delay—head to a 4S shop or professional repair center for a check-up, as unusual noises might indicate hidden risks.
