How to troubleshoot air suspension issues in an Audi A6?

I have been experiencing issues with my Audi A6's air suspension system. The car feels bumpy and unstable, and the warning light keeps coming on. How can I diagnose and fix this problem?

First, check the air suspension compressor for any leaks or damage. If necessary, replace it with a new one. Then, inspect the air springs and struts for wear and tear. It is recommended to replace them every 80,000-100,000 miles for optimal performance.

Another common cause of air suspension issues is a faulty control module. This can be diagnosed using a diagnostic tool or by a mechanic. If needed, replace the control module to solve the problem.
