The updated version introduces substantial changes aimed at increasing measurement reliability and preventing fraud or tampering. The main innovations include:

1. Stricter accuracy requirements for odometers

The 02 Series sets new limits on the accuracy of distance values recorded and displayed by the odometer. Manufacturers will need to ensure that the system measures and reports mileage with greater precision, minimizing allowable tolerances.

2. A new test procedure to verify compliance

To ensure vehicles meet the new accuracy criteria, the regulation introduces a fully updated test procedure. This procedure enables inspection bodies and technical services to verify more rigorously:

• the operation of the odometer,

• the consistency of the recorded values,

• the stability of the measurements under different operating conditions.

3. Stronger anti-tampering requirements

One of the most significant changes is the introduction of new anti-tampering requirements. The goal is to prevent any manipulation of the distance values recorded and displayed, combating issues such as:

• artificial reduction of mileage,

• software alterations,

• unauthorised interventions on ECUs.

These requirements aim to protect both consumers and the used vehicle market by ensuring transparency and reliability of data.
