Saab 9-7x low air suspension issue persists in cold weather on Saab 9-7x

Some Saab 9-7x owners report experiencing low air suspension issues in cold weather, which may be attributed to several factors. These owners have noted that a leak in the rear air suspension system can prevent proper calibration, resulting in the vehicle sagging. Additionally, colder temperatures can cause the rear suspension to lose pressure overnight, leading to a bumpy ride. Some owners find that the compressor fails to activate when the vehicle is started, which may indicate wiring or fuse/relay problems. Furthermore, if the compressor runs excessively even when the engine is off, it could suggest an insufficient battery amp issue or a malfunctioning sensor. To resolve these issues, owners are advised to check for leaks, monitor suspension pressure, and inspect the compressor system for any functional problems.
