Choosing the right BMW i4 device depends on the chassis, installed display and software, not the registration year alone. Select your vehicle and device version to view the applicable instructions. Different devices have separate mode sequences; their modes must not be combined.
- Quality connections — premium-quality plugs and heat-resistant cables for a neat, vehicle-specific fit.
- Discreet installation — integrates with the vehicle wiring at the specified fitting location.
- Matched to your BMW — choose the generation, model and installed display to see compatible device versions.
- Instructions follow your selection — activation, mode percentages and speedometer behaviour are shown for the chosen device only.
- Live Cockpit or Curved Display versions — only the display types explicitly listed for this series are supported.
- Not detectable after removal — once removed, use of the device cannot be detected through diagnostics. Remove it before any diagnostic inspection.

How it works
Every modern vehicle uses a CAN-bus network — a high-speed digital communication system that links the engine control unit, instrument cluster, gearbox, ABS, and dozens of other modules. Distance data travels across this network continuously, and the instrument cluster reads those signals to update the odometer.
The BMW i4 Mileage Blocker installs in-line on the specific CAN-bus line that carries distance pulses toward the instrument cluster. It intercepts those signals at the wiring level — before they reach the cluster — and, depending on the selected operating mode, suppresses them entirely or reduces them to a set percentage.
The device uses vehicle-specific, original-type connectors and fits entirely within the existing wiring loom. No wires are cut, no soldering is required, and no coding or software changes are made to the vehicle. Removing the device restores the vehicle to its exact factory state.
Because the device operates at the physical wiring layer — not through the OBD-II port or any software interface — its presence cannot be detected by standard diagnostic equipment. It leaves no trace in the vehicle's fault memory and does not trigger any warning lights. The device retains the last selected mode between ignition cycles.
