The case is part of legal action Mosley says he's taking in more-than 20 countries around the world.
Hamburg state court said Mosley was not present for the case's opening hearing Friday. The session ended with the court giving attorneys until Oct. 26 to provide more information.
Mosley successfully sued a British tabloid over a 2008 story headlined "Formula One boss has sick Nazi orgy with five hookers." Mosley has acknowledged the orgy, but says the story was an "outrageous" invasion of privacy and the Nazi allegation was damaging and "completely untrue."
