BMW Z4 Mileage Blocker

About the BMW Z4 Mileage Blocker

The BMW Z4 Mileage Blocker is a plug-in CAN-bus module made specifically for the BMW Z4 (See generation options). It fits in-line on the wiring behind the instrument cluster using connectors that match the factory loom, so there is no cutting, splicing, soldering or software coding. With the module active, the distance signal reaching the cluster is paused or reduced according to the mode you select; the speedometer and everything else on the dash keep working as normal.

Because it works at the wiring level rather than through the OBD port, it does not write anything to the car’s memory, does not trigger warning lights, and can be unplugged at any time to return the vehicle to standard. It is intended for dyno sessions, remapping and testing, track and off-road use, and vehicle development.

Options

• Short cable – standard length, sized to sit directly behind the cluster.
• Extended cable with quick removal (+$89) – roughly 45 cm (18 in) of extra cable plus a quick-release connector, so the module can be tucked behind a kick panel or lower dash trim and unplugged in seconds when needed.

Operating modes

• Operating modes are version-specific. Select the matching chassis, installed display and software for the applicable device sequence. Different devices have separate mode sequences; do not combine them.

Only the selected device’s mode set applies. Modes from different devices must not be combined.

How to change mode: shown for your selected vehicle and version below.
