Mercedes-Benz Mileage Blocker Installation Service

Ensure your Mercedes-Benz mileage is accurately managed during dyno testing, track days, or off-road use with our professional mileage blocker installation service in Slough. Our expert technicians specialise in luxury and performance Mercedes models, including AMG, E-Class, S-Class, and G-Wagon, providing safe and reliable installation that does not permanently alter your odometer reading.

Using a mileage blocker helps maintain precise performance data during testing and protects your vehicle’s long-term value. While these devices are designed for off-road and testing purposes, it’s important to note that we cannot guarantee they are undetectable.

At our Slough workshop, we provide brand-specific installation and guidance, ensuring your Mercedes remains fully operational and safe while using the blocker. Our team is highly experienced with luxury vehicles and high-performance cars, delivering professional, trustworthy service tailored to your exact needs.

Frequently Asked Questions

What is a mileage blocker?

A mileage blocker temporarily pauses the odometer during dyno testing, track days, or off-road use, ensuring extra miles aren’t permanently recorded in your Mercedes-Benz’s ECU.

Can I use a mileage blocker on all Mercedes-Benz models?

Yes — our service supports AMG, E-Class, S-Class, G-Wagon, and other Mercedes vehicles. Each installation is tailored to the specific model for optimal performance.

Does installing a mileage blocker affect my vehicle warranty?

When used correctly for off-road or testing purposes, mileage blockers generally don’t interfere with your warranty. However, unauthorised use on public roads may have implications.

Are mileage blockers detectable by dealerships or service centres?

We cannot guarantee they are undetectable. These devices are sold strictly for off-road and testing use.

How is a mileage blocker installed?

Installation is plug-and-play by trained technicians at our Slough workshop. We ensure your vehicle’s electronics remain fully functional while the blocker is active.

Can the mileage blocker be switched on and off?

Yes — most modules allow manual activation and deactivation, giving you full control during dyno runs, track testing, or off-road trips.
