"Stadler has requested that the Supervisory Board release him from his position in the Board of Management of AUDI AG and in the Board of Management of Volkswagen AG," Audi said in a statement.

Stadler's suspension from board duties will be temporary until the circumstances of his arrest are clarified, Audi said.

Audi, part of Volkswagen was forced to search for a new leader following the arrest of 55-year-old Stadler on Monday, almost three years after Volkswagen group admitted to rigging U.S. emissions tests on diesel engines.

Munich prosecutors said Stadler was being investigated for suspected fraud and false advertising and for his alleged role in helping to bring cars equipped with illegal software on to the European market.
