For the Volkswagen Group compliance is: Adherence to legal requirements, internal corporate policies, ethical principles, and self-imposed values for the protection of the company and its brands.


A company can only be sustainably successful if it acts with integrity, complies with statutory provisions worldwide and stands by its voluntary undertakings and ethical principles. Compliance must be second nature to all Group employees.

The group wide Code of Conduct (Our Code) is basis for all decisions taken in the company and offers guidance for ethical conduct. Other publications of the Volkswagen Groupoffer further detailed information and advice.

Compliance also means that each and every speaks up when the status quo appears to be problematic.

Our whistleblower system

Complying with statutory regulations and internal rules, and the principles laid down in our Code of Conduct and the Code of Conduct for Business Partners, has top  priority at Volkswagen Group Services GmbH. The success of our company is based on Integrity and Compliance. To meet these standards, it is important to learn of potential employee or supplier misconduct and to put a stop to it.

Therefore, we entrusted  the Central Investigation Office to operate an independent, impartial and confidential Whistleblower System on our behalf.  

A key pillar of our Whistleblower System is the principle of procedural fairness. It also guarantees the greatest possible protection for whistleblowers, persons implicated
and employees contributing to the investigation of reported misconduct.  

This also includes offering opportunities for anonymous reporting and communication. We assure not to perform any steps in order to identify anonymous  whistleblowers, who do not misuse our Whistleblower System. Retaliation of whistleblowers and all persons who contribute to investigations at Volkswagen Group Services GmbH will not be tolerated. Persons implicated are presumed innocent until the violation is proven. Investigations will be conducted with the utmost confidentiality. The information will be processed in a fair, fast and protected process.

How do we process your report?

The qualified and experienced colleagues at the Investigation Office examine every report for potential misconduct by a Volkswagen Group employee thoroughly and follow it up systematically.  First, you will get a confirmation of  receipt. The Investigation Office then assesses your report. This includes gathering facts particularly from the whistleblower. Only if this initial evaluation shows grounds for suspicion of a violation an investigation by a dedicated Investigating Unit will be started. Afterwards, the results of the investigation will be assessed by the Investigation Office and appropriate measures will be recommended. Information about the status* and the outcome of the procedure will be given to you without undue delay.

Potential violations of the Code of Conduct for Business Partners by suppliers, including serious risks and violations of human rights and environment by direct and indirect suppliers, can also be reported to the Investigation Office -  as well as reports requiring otherwise immediate action. The Investigation Office will inform the responsible departments, who will process the issue accordingly. This particularly includes taking the necessary measures to minimize or end violations and/or risks.

* The processing time varies depending on the subject of the procedure.
