The most likely cause is a leak of one or both of the air springs or perhaps the compressor drier. Spraying slightly soapy water around the compressor and drier assembly as well as on the rubber part of the air springs may reveal a leak. Sometimes, however, the leak on an air spring is located in a place you cannot see unless the spring is extended, as when hanging on a lift. A careful inspection is in order.
