BMW i4 Mileage Blocker

Choose your generation, chassis and installed display. Contact us with your vehicle make, model, model year or generation, and a photo of the instrument cluster if unsure.

Only the combinations listed in the vehicle selector are currently mapped.

Yes — the device works on all regional and continental variants of the supported chassis generation. Whether your vehicle was manufactured in Japan, Mexico, the USA or Europe, the mileage blocker connects to the same CAN bus network and operates identically. Country of manufacture has no effect on compatibility; what matters is the chassis code and instrument cluster generation listed in the vehicle selector.

Yes — the device is fully universal and automatically adapts to whichever unit of measurement is configured in your vehicle. Whether your instrument cluster displays miles per hour or kilometres per hour, the mileage blocker reads and interacts with the raw CAN bus data, which is unit-agnostic. No additional setup or configuration is required on your part.

No. The mileage change made while the device is active is permanent and irreversible — it will never jump, correct itself or display a different figure after the device is removed. The instrument cluster stores the modified value and treats it as the true odometer reading. There is no stored real mileage waiting to reappear.

Yes — we ship to most countries worldwide. Standard shipping rates are calculated at checkout for the majority of destinations. If your country is not listed at checkout or you would like a shipping quote before ordering, please contact us directly and we will provide a cost and estimated delivery time for your location.

No — the speedometer is completely unaffected. The mileage blocker targets only the distance-counting signal and leaves all other CAN bus traffic untouched. Safety systems including ABS, stability control and traction control continue to operate normally, and no warning lights or fault codes are triggered during use.

Yes — the i4 M50 is included where explicitly listed in the vehicle selector. The M50 uses the same Curved Display (iDrive 8 / 8.5) architecture as the other i4 variants, so the device operates identically across the range. Check the compatibility list to confirm your specific software version before ordering.

Yes — MileageBlocker.com is the developer and manufacturer of every device we sell. We do not resell third-party units or white-label products sourced from overseas distributors. Each device is engineered, firmware-programmed and quality-tested in-house at our workshop at Jessops Riverside, Sheffield, before it is dispatched. This means that when you buy from us, you are buying directly from the people who built the product — and who can support it properly if you ever need help.

No — and this is expected behaviour, not a fault. The device affects distance parameters exchanged between modules on the CAN Bus network. The module responsible for calculating board computer values sees the adjusted distance figure, so any reading it derives from that — including average MPG, fuel consumption, and estimated range — will not reflect real-world values while the device is in a non-100% mode. Your actual fuel consumption is not affected in any way; the engine burns exactly the same amount of fuel regardless of which mode is active. The inaccuracy is purely in the displayed calculation. Switch to 100% mode to restore accurate readings at any time. If you have questions specific to your vehicle, please get in touch and we will be happy to confirm.
