BMW 8 Series G14/G15/G16 & M8 F93 Mileage Blocker

Overview

The BMW 8 Series mileage blocker is a vehicle-specific electronic module for compatible G14, G15, G16 and M8 F93 models.

It connects behind the instrument cluster using the existing vehicle wiring, without cutting or soldering. The module manages new mileage recording through five selectable modes, with speedometer behaviour determined by the installed BMW software.

The correct instrument-cluster configuration is essential for compatibility, particularly where the vehicle has received software or firmware updates.

The BMW 8 Series mileage blocker supports:

• BMW 8 Series G14
• BMW 8 Series G15
• BMW 8 Series G16

Key Features

• BMW 8 Series and M8 compatibility: Designed for supported G14, G15, G16 and F93 instrument-cluster configurations.
• Plug-and-play installation: OEM-style connectors fit the original wiring without cutting or soldering.

• Working speedometer: Maintains speed display in the specified modes, except Mode 2.

How Does the BMW 8 Series Mileage Blocker Work?

The BMW 8 Series mileage blocker uses a microcomputer connected between the vehicle wiring loom and instrument cluster to filter mileage-related signals.

Depending on the selected mode, it stops, partially records or normally counts additional distance. Operating behaviour varies with the installed software, particularly between pre-2019 and newer configurations.

When the module is switched off, standard mileage counting resumes.

Vehicle-Specific Guidance

BMW G14, G15, G16 and F93 models may have different instrument-cluster and software configurations affecting mileage-recording modes.

Mode 1 is specified for pre-2019 software, while Mode 2 is described for newer software and does not provide a working speedometer display.

Compare the fitted dashboard with the product images and confirm the vehicle software before ordering.

Installation

The module connects inline with the original BMW instrument-cluster wiring.

1. Switch off the vehicle and allow its electrical systems to shut down.
2. Access and remove the instrument cluster using the correct vehicle-specific procedure.
3. Disconnect the original dashboard or instrument-cluster plug.
4. Connect the module between the vehicle wiring loom and instrument cluster using the supplied OEM-style connectors.
5. Where a Pin 1 marker is present, align it correctly and connect the cluster side first.
6. Ensure all plugs are fully seated and secure the wiring away from sharp edges or moving parts.
7. Refit the instrument cluster and surrounding trim.
8. Switch the vehicle on and verify normal display and vehicle functions.

No cutting or soldering is required.
