Volkswagen Mileage Blocker Installation Service

Ensure your Volkswagen’s odometer stays accurate during dyno testing, track days, or off-road use with our professional mileage blocker installation service in Slough. We have extensive experience with VW Golf R, GTI, Passat, Tiguan, and Arteon models, offering precision installation and reliable performance.

A mileage blocker allows your Volkswagen to record precise performance data without adding unnecessary miles to the odometer. These devices are designed for off-road and testing purposes, and while we provide professional installation, we cannot guarantee they are undetectable.

Our Slough workshop ensures model-specific installation, giving you confidence that your VW remains fully functional and safe while using the mileage blocker. We combine expertise with local knowledge, providing Volkswagen owners in Slough with a trusted service.
