Opel Mileage Blockers – Advanced Canbus Filters for Opel Vehicles

Take full control of your Opel vehicle’s mileage recording with our state-of-the-art Mileage Blockers. Engineered for precision and safety, these devices are perfect for preventing unnecessary mileage during vehicle testing, diagnostics, or controlled use.

What is a Mileage Blocker?

A Mileage Blocker is a smart device designed to stop your vehicle from recording mileage. Whether you’re testing your Opel on the road or running diagnostics, this device ensures no unwanted mileage is added, helping to maintain your vehicle’s value.

How Does It Work?

Our Mileage Blockers connect to the Controller Area Network (CAN Bus) — the system your Engine Control Unit (ECU) uses to communicate with other modules in your car. The blocker intercepts the CAN Bus signal going to the speedometer, preventing mileage from being recorded, while allowing all systems, including the speedometer, to function normally.

Easy, DIY-Friendly Installation

Installation is typically done behind the speedometer and requires no advanced technical skills. Clear DIY instructions are included, and we offer free video call support to help with both installation and removal.

Fully Untraceable & Vehicle Safe

Our Mileage Blockers for Opel are completely untraceable by any diagnostic tools — even dealer-level equipment. No data is stored, and when removed, there is no mileage jump, ensuring total discretion. Unlike low-cost alternatives, our devices are built with premium-quality components that won’t harm your Opel’s ECU or electrical systems.

Mileage Blocker vs Mileage Correction

Mileage correction tools only change what’s displayed on the dashboard while the actual mileage continues to be recorded. In contrast, our Mileage Blockers stop recording altogether, making them truly untraceable — even during official service visits.

Legal Use Guidelines

Mileage Blockers are legal to install and use in most countries, including the UK, US, and across Europe, for personal and testing purposes. However, using them to mislead or defraud buyers is illegal. Always use responsibly, for diagnostics, tuning, or testing, not deception.
