The Audi A3 8V, built on the MQB platform, shares many similarities with the Golf Mk7, including the cornering light system. However, coding these lights with VCDS can be tricky, and a common mistake is confusing “Abbiegelicht links/rechts” (cornering light left/right) with “Abblendlicht links/rechts” (low beam left/right). This article clarifies the correct VCDS procedure for A3 8V cornering light coding.
Understanding A3 8V Cornering Light Functionality
On the Golf Mk7 (and likely the A3 8V due to the shared MQB platform), static cornering lights function differently depending on the headlight type. With incandescent headlights, the fog lights (Leuchte12NL LB45 and Leuchte13NL RB5) are utilized for static cornering. VCDS adaptation channels within the “static AFS Light” group control this function.
However, for vehicles equipped with OEM HID headlights, the cornering function is managed by module 55 (hexadecimal), also known as the J745 module. While the BCM uses the same adaptation channels for both types of cornering lights, “Abblendlicht links/rechts” commands are typically absent in the factory settings for HID-equipped Mk7s and likely the A3 8V as well. This suggests that the low beams aren’t directly involved in the cornering function for HID systems.
Correctly Coding A3 8V Cornering Lights with VCDS
Instead of modifying “Abblendlicht” settings, the proper approach for coding cornering lights in an A3 8V with HID headlights likely involves configurations within module 55 (J745). This module controls the individual components of the HID headlight assembly, including the cornering light elements.
Further research and consultation with the VCDS community or relevant documentation may be necessary to pinpoint the precise adaptation channels or long coding modifications required for specific cornering light behaviors on the A3 8V with HID headlights.
Conclusion: Avoiding Common Coding Errors
When coding cornering lights on an A3 8V using VCDS, understanding the distinction between headlight types (incandescent vs. HID) is crucial. Avoid mistakenly adjusting “Abblendlicht” settings for HID systems. Instead, focus on configurations within module 55 (J745) to effectively control the cornering lights. Always refer to reliable sources and community forums for precise coding instructions specific to the A3 8V. This ensures proper functionality and avoids potential issues.
