I did a quick search but found nothing :/
All I can suggest is a full service and replacement seals and fluids.
Pinkbike have done a tech Tuesday article on them so have a read through that and maybe give it a go: http://www.pinkbike.com/news/Tech-Tuesday-Reverb-Refurbish-2012.html
If it is still under warranty though, you might as well send it back. See what other people say first though...
