VW Golf Active Info Display VCDS Coding Guide: Retrofit Your Digital Dash

Upgrading your VW Golf with an Active Info Display (AID)? This guide provides a comprehensive walkthrough for retrofitting and coding an AID using VCDS (Vag-Com Diagnostic System) for a VW Golf, specifically focusing on achieving proper functionality and display settings for variants like the Alltrack/SportWagen.

This retrofit provides a significant visual upgrade, replacing the standard monochromatic MFD with a vibrant, customizable digital instrument cluster. While the physical installation is straightforward, coding the new cluster can be challenging. This guide details the necessary VCDS coding steps to ensure your AID integrates seamlessly with your Golf.

Parts Required for AID Retrofit

Before starting, gather the following parts. Using your Golf’s VIN and consulting a VW parts department will help ensure compatibility:

• Active Info Display Cluster: 5G1 920 791 (source from reputable suppliers like e-acca.com or your local VW dealer).
• AID Bezel: 5G0 857 189 B FQZ (Polar Night). Note: This bezel color might not match your existing interior trim. Consider vinyl wrapping for a consistent look.
• Fiber Optic Splitter Cable: Search for “18e1 Kabel CD Wechsler Audi MMI 2G” on eBay. You only need the dark yellow splitter cable from this harness.

Pre-Installation Steps & Fiber Optic Cable Routing

1. VCDS Mapping: Using VCDS, create a complete backup of modules 17 (Instrument Cluster) and 5F (Information Electr.). This provides a crucial reference point should any issues arise during coding.
2. Trim Removal: Carefully remove the trim pieces surrounding the instrument cluster and the infotainment system. Refer to online resources or videos for guidance on disassembling these components without causing damage.
3. Cable Routing: Run the fiber optic splitter cable from the back of the infotainment unit (located in the glove box) to the instrument cluster opening. Fishing the cable through existing openings in the dashboard may require some patience.

Dealer Coding with ODIS

Have your VW dealership perform initial coding of the AID to your car and immobilizer using ODIS (Offboard Diagnostic Information System). Ensure both your keys are present during this process. Crucially, reconnect module 5F before ODIS coding to prevent potential coding conflicts. After ODIS coding, the AID will be functional but might display incorrect vehicle graphics (e.g., a standard Golf instead of a Variant/SportWagen).

Fine-Tuning with VCDS: Achieving Correct Display Settings

This is where VCDS comes in to fine-tune the AID’s display settings.

Module 17 (Instrument Cluster):

• Byte 2, Bit 3-6: Change to 50 (Model: Variant A) to correctly represent your Golf Variant/SportWagen. The default setting after ODIS coding might be 10 (Model: Variant 2).

• Optional: Byte 1, Bit 0 and Bit 3: Enable needle sweep and lap timer functionality.

• Byte 12, Bit 2: Enable Alternative Dimming Function.

• Adaptations – Display depiction: Change from Version 1 to Version 2 to enable navigation map display on the AID.

• Adaptations – Tube_version: Change to variant_2 for Alltrack/SportWagen specific speedometer and tachometer displays.

Module 5F (Information Electr.):

• Byte 22, Bit 0: Uncheck “Instrument Cluster Graphics [STANDARD]” to allow the AID to control the graphics.

• Optional: Byte 14, Bit 3: Enable toggling between FM and Satellite radio only (disables AM).

• Adaptations: Change the following channels:

  • Dashboard_Display_Configuration-ability_switch_nav_maps: On (enables touchscreen toggle for navigation maps)
  • Dashboard_Display_Configuration-call_picture: On
  • Dashboard_Display_Configuration-fastlist_most: On
  • Dashboard_Display_Configuration-navigation_map_compression_mode: H264
  • Dashboard_Display_Configuration-navigation_map_transmission_mode: MOST_streaming

After completing these VCDS coding steps, your VW Golf’s Active Info Display should be fully functional and correctly configured for your specific model. Enjoy the modern and customizable digital dashboard!
