You have not shared any information about what this "audit" of her prior marriage was about. If you are stating that she attempted to adjust her status based upon a past, fraudulent marriage and that her petition was rejected, she's going to be subject to a great deal of scrutiny the second time around. And whatever your motives, the prior marriage and long-distance relationship you describe do suggest a high potential for a determination that her intentions are fraudulent. She should consult an immigration lawyer.
