Connect the scanner to the OBD2 port, turn the ignition ON, and enter diagnostics. Select Skoda and use automatic vehicle detection.

From the main menu, open the Service section and select Odometer.

The scanner reads mileage values stored in multiple control modules.

On this vehicle, the values were:

• Engine control module: 488,059 km
• Instrument cluster: 488,059 km
• Power steering: 488,059 km

At this point, everything appears consistent.

Go back to diagnostics, open Control Units, and enter the engine control module (01 – Engine).

Enter Live Data and search for the parameter “control module distance driven”.

This parameter is not shown in the basic mileage function and must be accessed manually.

The engine control module reports the distance in meters.

Value recorded in this case:

• 541,923,491 m

Converted to kilometers:

• 541,923 km

Dashboard and service function:

• 488,059 km

Engine control module (live data):

• 541,923 km

Difference:

• Approximately 50,000 km

The mileage stored inside the engine control unit is significantly higher than the value shown on the dashboard and in other modules.

This indicates that the displayed mileage has likely been altered.
