Some Land Rover Range Rover Sport owners report experiencing a "Normal Height Only" message due to a faulty air suspension compressor, which is often linked to malfunctioning air suspension pumps. This issue can lead to a rough ride, poor handling, and decreased fuel efficiency. While the "Normal Height Only" message generally allows for safe driving to a local service station, it is advised to perform a fault code retrieval of the suspension system for diagnosis. The warning message may also appear with the Air Suspension Warning Lamp, indicating slow pressure increases or an inability to pressurize without air leaks. In some cases, owners may need to have the RLM Module flashed to ensure compatibility with the correct compressor. Additionally, some Land Rover dealers may suggest replacing the entire compressor assembly or changing the dryer, which can incur significant costs.
