How can I optimize the handling of my Audi A4's steering?

I've noticed that my Audi A4's steering has become stiff and unresponsive. What can I do to improve the handling and make it smoother?

First and foremost, make sure your tires are properly inflated. Low tire pressure can affect the steering and handling of your car. Also, check the alignment of your wheels and get a wheel alignment if needed.

Another thing to consider is the condition of your suspension system. If it is worn or damaged, it can greatly affect the steering and handling. Get it checked by a professional if you suspect any issues.

Check the power steering fluid level and top it up if needed. Low levels can cause the steering to feel heavy and hard to turn. Also, consider replacing the power steering fluid if it is dirty or contaminated.
