How to troubleshoot suspension issues in an Audi?

My Audi seems to be sagging a bit and the ride feels rougher than before. What could be causing this and how can I fix it?

First, check the air suspension system for any leaks. If there are no visible leaks, check the air compressor and replace if necessary. Also, make sure to check the struts and shocks for any wear and tear. If everything seems okay, it could be an issue with the electronic suspension control module. In that case, it's best to take it to a certified Audi mechanic for further diagnostics and repairs.

Another common cause of suspension issues in Audi cars is worn out control arm bushings. If the car is making clunking or rattling noises while driving over bumps, there's a high chance that the control arm bushings need to be replaced. It's best to have a mechanic inspect the car to confirm this.
