How to fix a squeaky suspension in an Audi A4?

My Audi A4's suspension has been making an annoying squeaking noise. It's starting to affect the performance of my car. What could be the cause and how can I fix it?

The most likely cause of the squeaky suspension is worn out bushings or ball joints. You can visually inspect these components for any signs of wear and tear. If they need to be replaced, it's best to take your car to a certified mechanic.

Another possible cause could be a lack of lubrication in the suspension system. You can try greasing the joints and bushings to see if it reduces the noise. If not, it's best to have a professional check it out as it could be a sign of a more serious issue.
