What are mileage blockers? 1

Technicians install Mileage Freezer on CAN-bus or FlexRay communication protocol to give the user control over each data set, such as driving speed, mileage data, or service information, which can then be modified to suit their needs.

The mileage blocker is an electronic device that stops counting miles/kilometres on vehicles while driving. Mileage blockers are designed to prevent a vehicle’s mileage recording during functionality testing. These top-of-the-line products are installed as a standard electronic control unit, be it a Range Rover, Ferrari or BMW.

What sets mileage blockers apart in the realm of automotive technology?

Mileage blockers, hailed as the savvy solution for odometer tampering, represent a technological marvel in the automotive industry. These ingenious devices, discreetly nestled within a vehicle’s intricate electronic architecture, serve a singular purpose: halting the relentless march of miles on the odometer. Unlike conventional odometer correction tools, which manipulate displayed mileage readings, mileage blockers intercept signals within the CAN-bus or FlexRay communication protocol, effectively freezing the odometer’s tally without leaving a trace.

Beyond their covert operation, mileage blockers boast unparalleled sophistication in evading detection. Diagnostic testers, renowned for their ability to scrutinize every byte of vehicle data, find themselves confounded by the elusive nature of mileage blocker modules. Advanced systems like Mercedes Star SDS Xentry or diagnostic tools from SnapOn, Launch, or Bosch are left perplexed, unable to retrieve any trace of mileage data from vehicles equipped with these blockers. Moreover, the installation process is a study in stealth, with no need for invasive wire cutting or splicing, ensuring a seamless integration that leaves no telltale signs of tampering.

What is the difference between mileage freezer and mileage correction?

The main difference is the purpose of the module. Many speedometer calibration and odometer rollback tools are available to change the mileage readings displayed on the speedometer. The device may be called differently:

  • speedometer correction;
  • odometer correction;
  • mileage correction;
  • speedometer rollback, etc.

All devices deal with displayed numbers.

The mileage locking tools interface with the Can-Bus system. It is called:

  • Run Stopper;
  • Odometer stopper;
  • Kilometre Stopper;
  • Can filter;
  • Stop-km;
  • Kilometre Freeze;
  • Speed blocker.

Compared to mileage correction tools, the main advantage of Odometer Stopper modules is that their operation cannot be tracked, since the data is not stored in any control unit. Diagnostic testers also do not detect stopped mileage when using the module. This does not apply to all devices and depends on the provider.

Can a mileage blocker be found?

Once installed, the module is hidden behind the dashboard, entirely invisible to the eye.

Many diagnostic machines, such as Mercedes Star SDS Xentry or even SnapOn, Launch, or Bosch Diagnostics, cannot read any data about the vehicle’s mileage.

Since no wires need to be cut or spliced when removing the jammer, no evidence is left on the tail that it was ever installed.

Finally, when the mileage blocker is removed from the vehicle, the mileage will not increase since all mileage data is filtered like the speedometer.

Mobile applications for mileage blocker devices

Most Mileage Freezer tools require vehicle buttons to switch from mode to mode and to turn the module on or off. However, some manufacturers have developed a smartphone application that allows you to change modes. App-enabled modules are already available on some vehicles and will soon be available from all manufacturers.

But remember that mileage blockers are designed to stop counting unnecessary miles when testing car productivity.
