What is the best way to fix a faulty air suspension in an Audi A2?

I have been experiencing issues with the air suspension in my Audi A2. The vehicle doesn't seem to be maintaining its height properly and I can feel a lot of bumps while driving. How can I troubleshoot and fix this problem?

To fix a faulty air suspension in an Audi A2, you can start by checking the air compressor, which is responsible for pumping air into the suspension. Make sure it is running properly and has enough air. If the compressor is working fine, you may need to check the air lines and connections for any leaks or damages.
