What are some common issues with the Audi A4's suspension system?

I recently purchased a used Audi A4 and noticed some strange noise coming from the suspension. What are some common issues with the A4's suspension system that I should be aware of?

One common issue with the Audi A4's suspension is a worn out strut mount. This can cause clunking or popping noises while driving, and can also affect the car's handling. My advice would be to have it checked by a mechanic and replaced if necessary.

Another common problem is with the control arms of the suspension. If they become worn or damaged, it can cause vibrations while driving and affect the car's alignment. My recommendation would be to have them inspected and replaced if necessary.
