Can a 4S shop detect odometer tampering?

[HavenFitz]

4S shops can detect odometer tampering. They can determine whether the odometer has been rolled back based on maintenance records and professional diagnostic computer tests. For some automatic transmission models, the diagnostic computer can also check the transmission mileage to verify if the odometer has been tampered with. Odometer tampering is a common phenomenon in the used car market, as consumers purchasing used cars often place high importance on the vehicle's mileage, leading to such practices. Generally, a diagnostic computer connected to the OBD interface can be used to roll back the odometer, but some models require specialized computers matched to the specific vehicle brand. For example, certain German car brands require their own brand-specific diagnostic computers for odometer adjustments.
