Key events

On September 18, 2015, the US Environmental Protection Agency (EPA) publicly announced in a “Notice of Violation” that irregularities in relation to nitrogen oxide (NOx) emissions had been discovered in emissions tests on certain vehicles of Volkswagen Group with type 2.0 l diesel engines in the USA. In this context, Volkswagen AG announced that noticeable discrepancies between the figures achieved in testing and in actual road use had been identified in around eleven million vehicles worldwide with type EA 189 diesel engines. On November 2, 2015, the EPA issued a “Notice of Violation” alleging that irregularities had also been discovered in the software installed in US vehicles with type V6 3.0 l diesel engines.

In the months after the International Council on Clean Transportation (ICCT) study was published in May 2014, the test set-ups on which the ICCT study was based were repeated in-house at Volkswagen AG and confirmed the unusually high NOx emissions from certain type EA 189 2.0 l diesel engines in the USA. The California Air Resources Board (CARB) – a part of the environmental authority of California – was informed of this result, and, at the same time, an offer was made to recalibrate the type EA 189 diesel engines in the USA as part of a service measure that was already planned in the USA. This measure was evaluated and adopted by the Ausschuss für Produktsicherheit (APS – Product Safety Committee), which initiates necessary and appropriate measures to ensure the safety and conformity of Volkswagen AG’s products that are placed in the market. There are no findings that an unlawful “defeat device” under US law was disclosed to the APS as the cause of the discrepancies or to the persons responsible for preparing the 2014 annual and consolidated financial statements. Instead, at the time the 2014 annual and consolidated financial statements were being prepared, the persons responsible for preparing the 2014 annual and consolidated financial statements remained under the impression that the issue could be solved with comparatively little effort as part of a service measure.

In the course of the summer of 2015, however, it became successively apparent to individual members of Volkswagen AG’s Board of Management that the cause of the discrepancies in the USA was a modification of parts of the software of the engine control unit, which was later identified as an unlawful “defeat device” as defined by US law. This culminated in the disclosure of a “defeat device” to EPA and CARB on September 3, 2015. According to the assessment at that time of the responsible persons dealing with the matter, the scope of the costs expected by the Volkswagen Group (recall costs, retrofitting costs and financial penalties) was not fundamentally dissimilar to that of previous cases involving other vehicle manufacturers, and, therefore, appeared to be controllable overall with a view to the business activities of the Volkswagen Group.

This assessment by the Volkswagen Group was based, among other things, on the advice of a law firm engaged in the USA for approval issues, according to which similar cases in the past were resolved amicably with the US authorities. The publication of the “Notice of Violation” by the EPA on September 18, 2015, which, especially at that time came unexpectedly to the Board of Management, then presented the situation in an entirely different light.

Extensive inquiries were also conducted at AUDI AG in relation to the potential use of unlawful “defeat devices” under US law in type V6 3.0 l diesel engines. The investigation conducted by Jones Day for Volkswagen AG also comprehensively covered this issue.

The AUDI AG Board of Management members in office back at the relevant time have stated that they had no knowledge of the use of unlawful “defeat device” software under US law in V6 3.0 l TDI engines until they were informed by the EPA in November 2015.

Within the Volkswagen Group, Volkswagen AG has development responsibility for the four-cylinder diesel engines such as the type EA 189, and AUDI AG has development responsibility for the six-cylinder diesel engines such as the type V6 3.0 l diesel engines.

Nothing from the publications made up to the time this report was prepared or from the ongoing investigations and interviews on the diesel issue has presented the Volkswagen AG Board of Management with any conclusive findings or assessments of fact that would result in a different assessment of the associated risks (e.g. investor lawsuits).

Additional expenses of €3.2 billion were recognized in fiscal year 2017. This is due to an increase of €2.2 billion in expenses for warranties and of €1.0 billion in expenses for legal risks. The main reason for this rise in provisions is that the buyback/retrofit programs for 2.0 l TDI vehicles in North America, which have to be implemented under the settlement deal, are more complex. Continuous monitoring of the program has shown that the scheme is more comprehensive and technically more challenging than expected; this also entails an extension to the program period.
