Whistleblower System

Welcome to the homepage about the Volkswagen Group Whistleblower System.

Complying with statutory regulations and internal rules has top priority at Volkswagen. We can only avoid damage  to our company, our employees and business partners if rules and standards are respected. Consequently, misconduct must be recognized swiftly, processed and immediately remedied.

That calls for vigilance on the part of everyone along with a willingness to draw attention to possible serious regulatory violations on the basis of concrete evidence. We also value information of this nature from business partners, customers and other third parties.

The whistleblower system guarantees the greatest possible protection for whistleblowers and persons implicated. An investigation is only initiated after very careful examination of the facts and concrete evidence of a regulatory violation. There will be strict  confidentiality and secrecy throughout the investigative process. Information will be reviewed fairly, promptly and in a sensitive manner.  




A list of all internal and external contact points is available from this page.

Where do I send my report?

All contact options along with details and comments on the disclosure of personal data can be found below.

Ombudspersons of the Volkswagen Group

"Ombudsman" is a term taken from the Swedish word for mediator or legal representative. Dr. Rainer Buchert and Thomas Rohrbach, the external ombudspersons appointed by the Volkswagen Group, act as special counsel to accept reports of potential statutory or internal violation of regulations or any other kind of harmful conduct in the Group, and to review these with respect to plausibility and substantiability. They consult with the whistleblower if necessary and if the identity of the whistleblower is known. Finally, they forward all the information that has been agreed with the whistleblower to the Investigation Office for further processing.

All information is treated as confidential and it is the whistleblower who decides whether he or she wishes to protect his or her identity vis-à-vis the Group. The ombudspersons appointed by the Group ensure that reports from whistleblowers who do not wish to be identified by the Company are forwarded to the Investigation Office anonymously.

If you want to get in contact with the Ombudspersons you can find their contact point on the following homepage: http://www.ombudsmen-of-volkswagen.com/

How do I make a report?

It is important to make sure the information contained in the report you submit to the Investigation Office is as concrete as possible so that it can be processed and investigated in the appropriate manner.

It is helpful if your report covers the following five questions:

- who?
- what?
- when?
- how?
- where?

Please make sure that the descriptions contained in your report can be easily understood by persons who are not specialists in your field. Maybe you would be available to answer further questions? That would be very helpful. If you would be willing to do so, but wish to remain anonymous and do not wish your identity to be disclosed to the Company, please contact the ombudspersons to make your report.
