German carmaker Volkswagen and parts upplier Bosch have asked a US Federal Judge to reject requests from European investors and vehicle owners to access more than 20 million pages of records turned over to investigators as part of the "Dieselgate" scandal investigation.
While Volkswagen has asked the judge to deny the request for documents which it claims are not sufficiently restricted to the case.
Bosch has in a separate filing asked the same judge to reject the request stating the request had not been filed properly.
Volkswagen has already agreed to pay over $15 billion dollars as compensation to the US government and owners after admitting to using a defeat device (designed with the help of Bosch) to cheat US emissions tests.
VW claims that German investigators have rejected document requests believing the documents would undermine their own investigations into the scandal that shook up the German car industry last September.
Bosch though claims that the two million documents it released to investigators contain "sensitive information, including competitively sensitive business documents and information that is protected under foreign data privacy laws."
Volkswagen is currently facing around 1,400 cases related to the DieselGate Scandal at the courthouse in the German city of Braunschweig, which is located about 37 kilometres away from Volkswagen's home base at Wolfsburg. The carmaker could end up paying out $9.1billion in damages to various investors.
