Legal & safety notice

When replacing an instrument cluster, it is important that the displayed mileage accurately reflects the vehicle’s true distance traveled. Always record the original mileage before removing the old cluster and keep clear documentation of the replacement process.

Mileage-related systems are regulated in many countries, so any synchronization or correction should only be done to match the vehicle’s actual, documented mileage. Never use this type of procedure to misrepresent a vehicle’s history.

Maintain transparent service records and follow local regulations to ensure the vehicle remains compliant and properly documented.
