We have used OBDSTAR X300M, X300 DP Plus to do mileage correction on Benz W204 before. After sorting out the data, we came to the conclusion: Mercedes Benz W204 (C Class) mileage can be adjusted by OBDSTAR X300M, X300 DP Plus and Digiprog3 on the table.
1.With OBDSTAR X300 DP Plus:
Insert the key to turn on the ignition on
Connect X300 DP Plus and Benz W204 instrument
Run X300 DP Plus programmer tablet
Tap Diagprogram>> ODOMETER>> BENZ>> BENZ newest version>> C CLASS>> W204>> Odometer recalibration
Read the original kilometer is 1664km
Input the new mileage 666 to write and modify data, wait a moment
Odometer correction complete
Now the mileage on the dashboard is 640km, it’s OK.
Remove dashboard and plug in a MB CAN Filter before mileage correction.
After connection, operate by this path: Vehicles >> Cluster Calibrate >> Benz >> Benz V30.35 >> C series >> W204
Then follow the prompt to adjust mileage.
For the full operation steps, check Mercedes C Class W204 Odometer Adjustment via OBDSTAR X300M
X300M only does C class W204 mileage correction. Need luck with other W204 series. If it says “Unknown version” it means this cannot be done.
