App control
The app lets you turn the blocker on for a test session or off-road day and back off afterwards, without touching the module. It’s especially useful on EVs like the MG4 and MG5, where the module sits behind the dashboard.
Fitting
The module installs behind the instrument cluster with no cutting or soldering, using the supplied long cable. DIY instructions and a free video call are included, or add our nationwide fitting service at checkout (UK only). Every module has a 12-month warranty, with express tracked shipping available.
FAQs
Can I remove it later? Yes. Unplug the module and the vehicle returns to normal.
Are mileage blockers legal? Fitting and using a blocker for testing, diagnostics, track days or off-road use is legal in the UK. It is illegal to mislead a buyer about a vehicle’s mileage, so always declare it when selling.
