Compilation of Volkswagen’s minimum standards

Our whistleblower system

Compliance with legal requirements and internal rules is a top priority at MOIA. Our company’s success is based on integrity and compliance. In order to live up to this aspiration, it is important to learn about possible misconduct by employees and prevent it. That is why we have commissioned the Central Investigation Office to operate an independent, impartial and confidential whistleblowing system on our behalf.

The qualified and experienced staff members at the Investigation Office check every report thoroughly and follow it up systematically.

An important pillar of our whistleblowing system is the principle of fair procedure. It guarantees the greatest possible protection for whistleblowers, affected parties and employees who help investigate the reported misconduct.

We also offer an anonymous reporting and communication option. We will not take any action to identify anonymous whistleblowers who do not abuse our whistleblowing system. Discrimination against whistleblowers or anyone who contributes to MOIA investigations will not be tolerated. The persons concerned are presumed innocent until the relevant violation is proven. Investigations are conducted with utmost confidentiality. Information is processed in a fair, fast and protected procedure.

Do you have any questions or feedback regarding a MOIA product or service?

If you have any questions about your new or used vehicle, feedback or complaints about services provided by MOIA or our business partners (e.g. car dealers, workshops), please feel free to contact

We ask for your understanding that the whistleblower system unfortunately cannot address, process or, in particular, forward customer concerns.
