As part of a fraud investigation, German authorities have raided Audi's German HQ in search of evidence related to the diesel emissions scandal.
"Audi spokesman Moritz Drechsel said that the raids were focused on the company headquarters in Ingolstadt and at its plant in Neckarsulm in the neighboring state of Baden-Wuerttemberg."
The raid hopes to uncover evidence to prove the theory that the emissions scheme went on for a decade, and executives knew all along.
Volkswagen's offices were also raided.
The decision to cheat on emissions has cost Audi $1.73 billion in earnings worldwide, according to Bloomberg.
