The suit says VW failed to disclose to U.S. investors that its "clean diesel" cars were exceeding vehicle emissions limits.
The automaker is in "advanced discussions" over an agreement that would further extricate it from the diesel emission cheating scandal.
The acquisition of PayByPhone gives the automaker "a charter to focus on general mobility services.”
The loss reflects VW's writedown of $18.2 billion for costs related to the scandal and analysts predict the final number could reach $32 billion.
"The emission crisis might cause lasting damage to VW’s once-solid reputation with adverse effects on its future earnings and cash flows," says Moody's.
