FAQ
What is a mileage blocker?
A mileage blocker is an electronic device that pauses mileage recording on your vehicle’s odometer. It’s designed for testing, diagnostics, or transport purposes—not illegal odometer tampering.
How does a mileage blocker work?
It intercepts signals between your car’s speed sensor and ECU, freezing mileage counters while driving. Our devices leave no error codes when installed correctly.
Will it damage my car’s ECU or trigger warnings?
No. Mileage Blocker devices use non-invasive modulation—they don’t rewrite ECU data or activate dash alerts.
Is it detectable during inspections or diagnostics?
Not if installed properly. Unlike cheap OBD tools, our blockers don’t store manipulation logs.
Can I install it myself?
Yes! We provide step-by-step video guides and wiring diagrams. For complex models, professional installation is recommended.
Which car brands/models are compatible?
Our blockers work with most vehicles (2000–2024)—BMW, Mercedes, Audi, VW, Toyota, etc.
Does it work on digital odometers?
Yes. Modern digital dashboards use the same sensor signals as analog ones.
What if my blocker malfunctions?
Contact our 24/7 support team. All devices include a 2-year warranty against defects.
Do mileage blockers really work?
Yes, mileage blockers do work. These advanced tools are designed to pause the mileage recording system in real-time, preventing distance data from being stored in the vehicle’s control units. However, they are intended strictly for off-road, testing, and diagnostic purposes.
What is a mileage blocker on a car?
A mileage blocker—also called a mileage freezer—is a compact electronic device installed in specific vehicle models. It temporarily halts the odometer from tracking distance traveled. When active, it prevents mileage data from being recorded, even across multiple control units, making it undetectable during standard diagnostics.
How to find if a mileage blocker is installed in a vehicle?
Detecting a mileage blocker can be challenging, but here are key steps to uncover potential tampering:
Check service and maintenance records for consistent mileage logs.
Inspect the overall vehicle condition—interior wear vs. displayed mileage.
Review official MOT and vehicle history reports.
Run a full diagnostic scan using professional-grade tools.
Consult a trusted mechanic with experience in odometer systems.
Examine tires and brake wear for signs of extended use.
Look for aftermarket modifications or tampered wiring near the dashboard.
How to install a mileage blocker?
Installation usually requires basic automotive knowledge. In most cases:
Remove the instrument cluster or speedometer by loosening screws.
Disconnect the relevant connectors at the rear of the speedometer.
Attach the blocker module securely between the speedo and the vehicle’s cable harness.
Reassemble the dash and test functionality.
⚠️ For best results and safety, we recommend professional installation—or choosing a plug-and-play solution from our Shop.
What kills high-mileage cars?
Over time, high-mileage vehicles experience engine wear, particularly in components like piston rings, valve seals, and gaskets. These parts can lead to increased oil consumption and loss of compression, reducing performance. Other culprits include poor maintenance, low-quality fluids, and neglected timing belts.
What happens when you remove a mileage blocker?
If you’re using a high-quality mileage blocker like the ones we offer, your odometer reading will not jump forward or display incorrect data once the blocker is removed. Our modules are designed to prevent mileage corruption and keep your vehicle’s systems stable.
What reduces car mileage efficiency?
Several driving habits and conditions can lower fuel economy:
Aggressive driving (rapid acceleration & braking)
Excessive idling
Under-inflated tires
Poor engine maintenance
Carrying unnecessary weight
Using low-grade fuel or oil
Smart driving can improve fuel economy by up to 30%.
How do I clear or reset car mileage?
Clearing mileage is illegal if done to mislead buyers. For older mechanical odometers, this involves removing the unit and manually rolling back the numbers—often leaving signs of tampering. For digital odometers, specialized tools are used. However, odometer fraud is a criminal offense under UK law.
How is mileage tracked in vehicles?
Mileage is tracked through the vehicle’s odometer, which receives signals from the wheel speed sensors and ECU (Engine Control Unit). For personal logs, drivers can also manually record trip details including:
Date and time
Starting and ending mileage
Purpose of trip
Location details
Maintaining this record is useful for tax deductions and business mileage claims.
Do mileage correction tools work?
Yes, mileage correction tools are used to recalibrate or adjust the odometer—legally in cases like dashboard replacement. However, some people misuse these tools for fraudulent purposes. That’s why it’s important to use such devices transparently and only for legitimate needs.
