Fraud and modifications in used car markets

Overview

The used car market faces various forms of fraud and unauthorized modifications that can impact vehicle performance and value.

One issue involves unauthorized engine software modifications, commonly known as ‘chip tuning’. Buyers can detect these changes by comparing ECU software versions and checksums against manufacturer databases, checking flash counters in controllers, or looking for physical signs of manual programming on screws and seals. Such modifications can lead to denied warranty claims and increased mechanical wear.

Odometer tampering remains a widespread problem where sellers artificially manipulate mileage to inflate prices. Recent research by carVertical, covering 18 countries, indicates that approximately 30.3% of European buyers have purchased a vehicle with tampered mileage or know someone who has. A significant gap in consumer awareness exists, as 75.8% of European buyers do not know how to report odometer fraud or how to recover lost funds.

New data suggests a correlation between vehicle damage and mileage manipulation. Across the 18 countries studied, 61% of vehicles with modified odometers had recorded damage, compared to 47.8% of those with authentic mileage. In Romania, 67.1% of vehicles with rolled-back odometers had a history of damage.

In Denmark, an analysis of vehicle inspection reports from the Danish Road Safety Authority’s Motor Register indicates that approximately one in fifteen used cars—roughly 6.75 percent of the total stock—is suspected of having its mileage tampered with. The prevalence of fraud increases with vehicle age; for cars at least ten years old, the suspected proportion rises to 10.2 percent. A primary indicator of manipulation is a decrease in recorded mileage between consecutive inspections.
