Enable Digital Speedometer

Unlock the large digital speed readout hidden inside the G-series instrument cluster. The hardware is already there on all G-platform cars — you just need to activate it via the KOMBI module.

1 Prerequisites

ℹ️

Requires BimmerCode Expert Mode. The digital speedometer parameter is not exposed in standard mode. Applies to G-series cars with the standard round cluster — cars ordered with the Live Cockpit Professional (large digital cluster) may have this already active.

  • BimmerCode app with Expert Mode
  • Compatible OBD2 adapter (Veepeak BLE+, OBDLink MX+)
  • Ignition ON, engine off or running

2 Coding Parameters

Two parameters in the KOMBI module control digital speed display activation and the display format.

Geschwindigkeit_digital_Einheit km_h or mph km_h Select your preferred unit
⚠️

On some 2020+ G20 builds, the parameter name appears as digital_speedometer in English. The value logic is the same — enable / disable.

3 Step-by-Step

  1. Connect OBD2 adapter and open BimmerCode

    Plug the adapter into the OBD port. Open BimmerCode, allow it to connect and identify your chassis.

  2. Expert Mode → KOMBI

    Tap Expert Mode, then select KOMBI from the module list. Let it read current values.

  3. Search for Digitalanzeige_Geschwindigkeit

    Use the search bar, type Digital. Find Digitalanzeige_Geschwindigkeit and change it from nicht_aktiv to aktiv.

  4. Set your preferred unit (optional)

    If you want mph instead of km/h, find Geschwindigkeit_digital_Einheit and change to mph.

  5. Code and verify

    Tap Code. After success, turn ignition off, back on. The digital speedo should appear in your cluster — typically in the center of the analog gauge area or in a dedicated zone depending on your cluster variant.

4 Toggle via iDrive

Once coded active, you can often toggle the digital speedo display via iDrive settings under Settings → Displays → Instrument cluster without needing to recode. The coding sets the capability as available; iDrive controls the view preference.
