Change modes via smartphone app or press and hold the Return button ↩️ for approx. 10 seconds.

The mode is confirmed by sounding the “warning signal”. (Mode 1 is always active during installation)
Example: 1x warning signal = mode 1, 4x warning signal = mode 4

Repeat the process to switch from mode to mode.

Mode 1
The mileage counter is stopped 100%

The speed indicator doesn't work

10% of the driven mileage are counted and 1/10 of the actual speed is shown on the speedometer.

EXAMPLE: You drive 60mph and the speedo will show 6mph

Mode 3
The mileage is halved (50%) and the speedometer also shows 50% of the actual speed.

Example: You drive 100 mph on the speedometer 50 mph are displayed

Mode 4
The mileage counter is stopped 100%

The speed indicator works

Mode 5

If the speed in your vehicle does not work properly, a calibration is necessary.

To start the calibration press the return key 10 times when the module is on.
Ideal for calibration is a speed of 60KM/h or 60MP/h.
After that you can adjust the speed with the arrow up and down keys. (Please press the buttons in larger intervals & observe whether the speed changes during the ride on the speedometer).
If the speed is set correctly, please press the OK button until an acknowledgement appears (speedometer needle drops to 0KM/h or the vehicle beeps 1x briefly).
Finally, press the Return key 12 times to exit the calibration mode.

Mercedes C-Class, W204, Kilometer Stopper tool always maintains the last applied settings. Hence, you don’t have to change the settings before starting a car next time.

The device can be activated or deactivated, either while in motion or when stationary.

What is Mercedes C-Class, W204, Odometer Blocker or Mileage Correction Tool?

Mercedes C W204, Mileage Blocker / Odometer Blocker is meant for stopping the mileage in a car while testing its performance. At Super Kilometer Filter you can buy the best module with genuine components. Whether the digital odometer of your vehicle counts mileage in miles or kilometers (km), the device will work equally efficiently. Our programmers write software specifically for each maker and model to make sure that it works flawlessly. Install the module and use pre-determined key combinations to change from mode to mode.

We don’t sell Mileage Correction tools for Mercedes C W204, as they are meant for deceitful purposes and can solely remove the mileage figures from odometers. They are usually used to rewind / rollback the distance traveled. However, cars have multiple data storage units and roll back tools still fail to reverse the mileage altogether.

We offer a wide variety of Mileage Stopper devices for various vehicles. The Mileage Blocker tool works perfectly on a diesel-gasoline engine, as well as, Plug-in Hybrid Electric Vehicles (PHEVs) and Electric cars. The installation process is the same for all the models and doesn’t require in-depth knowledge of a vehicle’s maintenance. Plug it between the port of the speedometer and the instrument cluster and you can enjoy all the benefits of this unique module.

Mercedes C W204, Mileage Blocker can be activated or deactivated anytime, whether the car is in motion or stationery.

The Mileage Blocker unconditionally removes the mileage. The mileage figures will remain unchanged even after removing the module from the car. You can use our Mileage Blocker to alter the mileage and remove it anytime. Stopped mileage will not increase spontaneously after removing the module. However, in most cases, error messages should be deleted after removing the tool. Can Communications save any interruption messages as error messages. These are sporadic errors that do not necessarily have to be deleted, but it is recommended.
