How do I troubleshoot my Audi's air suspension system?

My Audi Q5's air suspension seems to be acting up. Sometimes it doesn't inflate properly and sometimes it's too stiff. What could be causing these issues and how can I fix them?

First, check your air compressor and valves for any leaks or damage. This could be causing the inconsistency in suspension levels. If everything appears to be functioning properly, it may be an issue with the air springs themselves. Consider having a professional mechanic inspect and possibly replace them.

Make sure your Audi is regularly serviced and all suspension components are checked and replaced as needed. It could also be helpful to consult with your dealership for any potential software updates that could improve the performance of your air suspension system.

One potential cause of air suspension issues could be a faulty suspension control module. This component controls the inflation and deflation of the air springs and can sometimes malfunction. If the issue persists, consider having it checked and possibly replaced by a certified mechanic.
