If you’re carrying out diagnostics or performance testing on your Vauxhall, a mileage blocker is a reliable way to prevent unnecessary mileage from being recorded. This smart, plug-and-play device stops your vehicle from tracking distance while it’s in use — ideal for garages, workshops, and private off-road testing.
In this guide, we’ll explain how the Vauxhall mileage blocker works, when to use it, and why it’s the better alternative to traditional mileage correction tools.
The Vauxhall mileage blocker is a precision-built module that prevents your car from logging mileage during operation. It does not erase or roll back your odometer — instead, it temporarily stops the system from recording any new distance.
It works across all key control units, including your instrument cluster and ECU, which means no mileage data is stored while the device is active. This makes it perfect for off-road, professional use.
The mileage blocker is designed for responsible use in workshop environments and off-road settings. It’s commonly used for:
ECU diagnostics and fault testing
Dyno or emissions testing
Post-repair test drives
Performance tuning
⚠️ Important: This tool should never be used on public roads or for dishonest purposes. It’s a legal solution only when used in appropriate testing scenarios.
The device prevents mileage from being recorded not just on the dash, but across all ECUs. This makes it fully undetectable via OBD or diagnostic tools.
Manage the blocker with ease via the SKF Speed App. Turn it on or off from your smartphone — even while the vehicle is moving.
Installation is quick, clean, and doesn’t require cutting wires. Simply connect the blocker using your Vauxhall’s original plugs.
Whether you drive a Corsa, Astra, Insignia, Mokka, or Combo, each version of the mileage blocker is designed to be fully compatible with your specific model.
Activate or deactivate the blocker while driving using the app or, if supported, your vehicle’s steering wheel buttons.
This tool is only intended for legitimate, off-road use. Using it to mislead potential buyers or alter a car’s history is illegal and can result in severe penalties, including fines or prosecution.
By contrast, when used properly, the mileage blocker is a responsible and effective way to test or maintain your Vauxhall without impacting its recorded mileage.
The mileage blocker is the ideal solution for technicians, mechanics, and enthusiasts who need to perform testing or tuning without altering mileage records. It’s undetectable, easy to install, and built specifically for your Vauxhall.
Use it ethically, install it properly, and enjoy complete control over your vehicle’s mileage tracking — legally and safely.
