Odometer Fraud Still Happens Frequently
Anyone buying a used car wants certainty about the vehicle’s mileage. Unfortunately, odometer fraud is still a common problem, especially with imported vehicles. In cases of odometer fraud, the mileage of a car is rolled back to make the vehicle appear less used than it actually is. This can have major consequences for both the value of the car and future maintenance costs.
Maintenance History Helps Verify Mileage
When you suspect possible odometer fraud, it is important to investigate the vehicle’s history as thoroughly as possible. One of the most valuable sources of information is the maintenance history. During maintenance visits, garages almost always register the service date, mileage, and workshop details. By comparing these records chronologically, unusual mileage jumps or inconsistencies often become visible very quickly.
Paper Service Books Can Be Manipulated
In the past, this information was mainly stored in a paper service booklet. However, paper maintenance books also come with risks. Service booklets can be forged, stamps can be copied relatively easily, and handwritten mileage entries do not always guarantee reliability. A fully stamped service booklet is therefore not automatically proof that the mileage is genuine.
Why Digital Service Records Are More Reliable
This is exactly why reliable digital data has become increasingly important. The most valuable information often comes directly from the manufacturer through official dealer maintenance records. These records are stored in the vehicle brand’s Digital Service Register (DSR), also known as the digital service book.
Within a DSR system, maintenance events are digitally recorded together with dates and mileage readings. Because this data comes directly from official dealer systems, it is generally considered more reliable than a traditional paper maintenance booklet.
Access to DSR Data Is Often Limited
The challenge is that DSR information is not always easy to access. Every manufacturer uses its own system, and the data is usually only visible to official dealerships or sometimes the current owner of the vehicle. For someone trying to verify a used car before purchase, it can therefore be difficult to review this information in advance.
Digital Maintenance Data Can Reveal Fraud
Even so, these digital records can be crucial when investigating possible odometer fraud. That is why it is wise not to rely solely on a paper service booklet, but also to request digital maintenance records, invoices, and dealer history whenever possible.
The more independent sources confirm the same mileage readings, the more trustworthy the vehicle’s history becomes.
VehiclePass Helps You Access DSR Maintenance Data
VehiclePass helps make Digital Service Register (DSR) data more accessible. Maintenance registrations stored within the digital service book usually include mileage readings as well. These records can provide a strong indication of whether the current mileage shown on the dashboard is logical compared to the vehicle’s historical usage.
By reviewing official maintenance data, you can often better estimate how many kilometers a vehicle has driven per year and whether the timeline matches the story being presented by the seller.
