Most likely an air leak that is small enough that your compressor can keep it filled. You need to get it fixed before it wears out the compressor.

This thread needs to be moved down under Tech and Suspension.

Fran,
Just like 2ManyMarks said, you probably have a leaking rear air spring ... just like having a leaking tire.
The Club recommends Arnott replacement air springs.
What have you done since posting?
