Škoda Octavia pre-purchase inspection — diagnostics revealed a mileage of over 523,000 km
The listing and the odometer showed a mileage of about 183,000 km. During a detailed computer diagnostic, several control units revealed significantly higher mileage figures. One record showed that as of 2026-07-25 the car's actual mileage already reached 523,096 km — confirming a major discrepancy between the declared and actual mileage.
Dashboard
During the inspection, the dashboard showed a mileage of about 183,000 km. The same mileage was stated in the car's sale listing.
Computer diagnostics
During diagnostics, mileage data from individual control units was checked. Several modules showed values exceeding 521,000–523,000 km.
Mileage discrepancy
The difference between the dashboard reading and the diagnostic data was about 340,000 km — a major discrepancy in the car's history that cannot be detected by visual inspection alone.
The point of the inspection
This case shows why, before buying a used car, it's important to check the mileage not just on the dashboard but also across different electronic control units.

The declared mileage of about 183,000 km did not match the data stored in several of the car's control units. Diagnostics revealed over 523,000 km, so a significant mileage discrepancy was identified before the purchase.
