Why does my Audi A4 make a loud noise when turning left?

I recently noticed that my Audi A4 makes a loud, grinding noise whenever I make a left turn. It doesn't happen when turning right. What could be causing this issue and how can I fix it?

It sounds like you may have a worn-out CV joint. This is a common issue in older Audi A4 models and can lead to loud noises when turning. It's best to take your car to a mechanic to have it inspected and potentially replaced.

Your power steering fluid may be low. Check the fluid levels and top it off if necessary. Low fluid can cause noise when turning as the power steering system is not able to work properly.

Make sure your tires are properly inflated and in good condition. Worn or uneven tires can also cause noise when turning. Consider getting an alignment if needed.
