It is now nearly two months since the firm was plunged into a crisis after the US Environmental Protection Agency accused it of cheating diesel emissions tests, which has in turn led to the recall of millions of cars globally, replacement of its chief executive and top comms executive, and a large financial loss in Q3.
Two statements were issued last night by the firm's headquarters in Wolfsburg, Germany, and then distributed by local press teams to journalists. Speaking to PRWeek, a member of the UK press team said he could not comment further on the statement.
The first statement began: "The Volkswagen Group is moving forward with the clarification of the diesel issue: during the course of internal investigations irregularities were found when determining type approval CO2 levels.
"Based on present knowledge around 800,000 vehicles from the Volkswagen Group could be affected." The statement went on to say that it would notify type approval agencies - the organisations in each market who approve cars for public use - and that an initial estimate puts the "economic risks" of this discovery at "approximately" €2bn ($2.2bn, £1.4bn).
The statement also said that the "majority of the vehicles concerned have diesel engines", and that the safety of the vehicle was "in no way compromised".
Matthias Müller, the global CEO of Volkswagen, said: "From the very start I have pushed hard for the relentless and comprehensive clarification of events. We will stop at nothing and nobody. This is a painful process, but it is our only alternative. For us, the only thing that counts is the truth. That is the basis for the fundamental realignment that Volkswagen needs.
"The Board of Management of Volkswagen AG deeply regrets this situation and wishes to underscore its determination to systematically continue along the present path of clarification and transparency."
A second statement, from the firm's supervisory board, said that the board was "deeply concerned" by the discovery, saying: "These irregularities came to light during the clarification process which, as announced, is being relentlessly and comprehensively pursued."
It concluded: "The latest findings must be an incentive for the Supervisory Board and the Board of Management to do their utmost to resolve such irregularities and rebuild trust.
