Researching the German used car market means looking beyond a single history report. As in the wider used car market, records may be incomplete or held by different organizations. Data protection, including the BDSG (Bundesdatenschutzgesetz), can affect access to personal information, but it is not a blanket ban on recording mileage or accidents.
Vehicle Records and Data Protection
Discussions on Reddit sometimes attribute every gap in a German vehicle report to privacy law. The reality is more nuanced. In its 9 November 2023 judgment in C-319/22, the Court of Justice explained that a VIN number can be personal data where it allows the holder to identify a natural person. It also dealt with the access that independent operators are legally entitled to. That doesn’t mean a complete accident record is publicly available; compare the coverage described in individual service reviews.
Service Book – Scheckheft

A service book, or Scheckheft, and digital service records can help document maintenance. Ask for invoices and, where possible, confirm the entries with the workshop that made them. As with VIN decoders, what counts is the information that’s actually there. Neither buying from a dealer nor a stamped book proves on its own that the history is complete or authentic.
Online Verification

Platforms like informa HIS GmbH may help. This company manages the Indications and Information System ("HIS") of the German insurance industry, aiming to identify and prevent insurance fraud. HIS serves as a tool for insurers to verify information in insurance applications and investigate suspicious damage claims. However, the process can be complicated, and you have to enter all the required information.
VIN Verification at Dealerships
An authorized workshop may be able to tell you what records it holds and when it can share them. Ask about access with the seller’s help, or their consent if that’s required. A dealership VIN check is one more source of evidence, but neither a workshop nor Vin Decoder Providers will necessarily have details of work done elsewhere or of every past incident.
Conclusion
Vin Decoder Providers can’t include records they never receive. Use service documents, available reports and an inspection together. The European Court of Justice case discussed in the original article has since been decided, as explained above, and the ruling shouldn’t be read as a promise that every vehicle history will become publicly accessible.
