"FRANKFURT — German officials included the offices of both Volkswagen’s chief executive and the head of the Audi division when they raided company premises last week as part of an investigation into emissions fraud, according to a copy of the search warrant.

The warrant, whose contents were viewed by The New York Times, was first reported on Sunday by the German newspaper Bild am Sonntag. It does not identify Matthias Müller, Volkswagen’s chief executive, or Rupert Stadler, head of the Audi luxury car division, as suspects in the case.

Investigators do not yet have enough evidence to determine who is responsible for illegally manipulating diesel motor software to deceive American clean-air regulators, according to the warrant."
