My front driver side height level sensor broke, which wouldn't allow the front suspension to rise just to be driveable. I ended up replacing my compressor and 2 front air bags since they were leaking air also. And my compressor had started to make a loud knocking sound. Either way, I recommend converting to shock and spring. They make kits for this car. The air suspension height level settings are barely messed with, and its not worth the unreliability issues.
