Want a clear, digital speed readout on your Volkswagen’s dash? This guide shows you how to activate the large digital speedometer, often called the “big speedo,” on your Multi-Function Display (MFD) or Driver Information System (DIS) using VCDS. This modification works on various Volkswagen models, including the Mk6 Golf, Mk3 Scirocco, Passat, EOS, and T5.1 Transporter.
Activating the VCDS Big Speedo: A Step-by-Step Guide
This modification requires access to a VCDS diagnostic tool. If you have VCDS, follow these steps:
-
Connect and Select: Connect your VCDS interface to your vehicle’s OBD-II port and launch the VCDS software. Select “Control Module 17 – Instruments.”
-
Access Long Coding: Navigate to the “Long Coding” section within the Instruments module.
-
Modify Byte 0: Locate “Byte 0” and focus on “Bit 4-7.” This section controls the region settings for your vehicle’s display.
-
Change to “Rest of World”: Change the current setting (likely set to your specific country) to “Rest of World.” This crucial step enables the MPH display and allows access to the big speedo feature.
-
Save and Exit: Click “Exit” and then confirm the change by clicking “Do It!” This saves the new coding to your instrument cluster.
-
Configure Your DIS: Disconnect your VCDS interface and turn your attention to your vehicle’s DIS.
-
Adjust DIS Settings: Navigate to the settings menu within your DIS.
- Deactivate Alt Speed: Uncheck the option labeled “Alt. Speed DIS.”
- Enable Digital Speedo: Go to “MFD Data” and check the “Digital Speedo” option.
- Set Units to MPH: Return to the main settings menu and select “Units.” Choose “Consump./dist.” then scroll down and select “mpg (UK), mi” to display speed in miles per hour.
After completing these steps, the small KPH display in your DIS/MFD will be replaced with the prominent digital speedometer showing speed in MPH.
