A mileage blocker is an advanced electronic device that stops your vehicle from recording miles or kilometers while driving. It’s most useful during car testing, dyno runs, or vehicle diagnostics, where accumulating unnecessary mileage can impact value or data accuracy.
Unlike other tools that roll back or alter displayed mileage, mileage blockers prevent mileage from being recorded in the first place—making them completely untraceable.
Mileage Blocker vs Mileage Correction Tools: What’s the Difference?
Not the same. Here’s the breakdown:
- Mileage Correction Tools (also known as speedometer correction, odometer rollback devices, mileage clockers):
These tools edit the numbers already displayed on the dashboard. They’re detectable and often leave digital footprints in the car’s ECU system. - Mileage Blockers:
They communicate directly with the vehicle’s CAN bus system, blocking mileage recording across all ECUs, not just the dash. This makes them 100% untraceable—even with advanced dealer diagnostic tools like Mercedes Star SDS or Bosch Diagnostics.

Modes & Customization: More Control, Your Way
Mileage Blockers UK offer multiple usage modes. Depending on your car model, you can:
- Record 0%, 10%, or 20% of actual mileage
- Switch modes while driving or stationary
- Keep the last-used mode even after restarting the car
This flexibility helps especially if you’ve changed tire sizes or use your car in different test environments.
Why Modes Matter: Tire Size and Data Accuracy
Slight changes in tire size can cause major discrepancies in recorded mileage. Mileage blockers with custom modes help correct those differences—keeping your car’s data accurate for diagnostics and testing.
What Is CAN Bus and Why Does It Matter?
The CAN bus is like your car’s central nervous system. It allows all your car’s computers (ECUs) to talk to each other.
Mileage blockers that work on the CAN bus level (like ours) are more advanced because they block mileage from being stored anywhere, not just from being displayed.
Will the Mileage Jump Up When I Remove the Blocker?
Not with Mileage Blockers UK. Unlike low-quality knock-offs, our modules ensure that the mileage remains as it was when you remove the blocker—no “catch-up” spikes.
What If I See a Warning Light?
If installed correctly, you won’t see any fault codes or dash lights.
All modules are clearly marked for correct installation. Just follow the instructions—no guesswork.
