Audi A8 - How to troubleshoot a malfunctioning air suspension?

I recently noticed that my Audi A8's air suspension is not functioning properly. The car's ride is bumpy and uneven, and there are strange noises coming from the suspension. Is there a common issue with the air suspension system in Audi A8? How can I troubleshoot and fix it?

First, check the air compressor and make sure it is working properly. This is often the cause of suspension issues in Audi A8s. If it's not the compressor, check the air lines for any leaks or damage.

If the compressor and air lines seem fine, the issue may be with the air springs or shocks. These components can wear out over time and need to be replaced. It's best to have a professional mechanic inspect and replace them for you.

Another possible cause of air suspension problems could be a faulty control module. This can be diagnosed with a diagnostic scan tool. If the control module is the issue, it will need to be replaced by a qualified technician.
