This article guides you through locating the Lane Departure Warning module using VCDS (Vag-Com Diagnostic System) for Audi A6/A7 (2012-Current) models equipped with Active Lane Assist. We’ll delve into the coding process and address common questions regarding calibration. This guide assumes your vehicle has Adaptive Cruise Control (ACC) and the necessary hardware for Active Lane Assist, including the 85-On Board Camera and 8E-Image Processing modules.
The windscreen camera crucial for both Adaptive Cruise Control and Lane Assist.
Understanding Active Lane Assist and its Module Location
Active Lane Assist helps prevent unintentional lane departures by providing steering assistance and warnings. It relies on the 8E-Image Processing module, often referred to as the Lane Departure Warning module in VCDS. This module processes data from the front camera to identify lane markings. You’ll find it listed as “8E-Image Processing” within the VCDS software. This module is key to enabling and configuring the Active Lane Assist system. Before 2012, these systems were only capable of Lane Departure Warning, a passive system providing vibration alerts without steering intervention.
VCDS Coding for Active Lane Assist
Accessing the 8E-Image Processing module via VCDS is crucial for activating and customizing Active Lane Assist. While the module’s physical location isn’t directly accessible through VCDS, the software allows you to modify its coding to enable the system. Here’s a breakdown of the coding process using VCDS:
Important Modules: Ensure modules 10 (Park/Steer Assist), 16 (Steering Wheel), 17 (Instruments), 44 (Steering Assist), 85 (On Board Camera), and 8E (Image Processing) are recognized in VCDS.
Coding Steps:
-
Module 10 – Park/Steer Assist: Enable “Lane Maintenance Assist (PR-7Y4/7Y5) installed” in Byte 1, Bit 5.
-
Module 16 – Steering Wheel: Change Byte 2, Bits 6 & 7 to “C0 Lane Assist with Heading Control installed”.
-
Module 44 – Steering Assist: Enable “Lane Assist installed” in Byte 2, Bit 0.
-
Module 8E – Image Processing (Lane Departure Warning Module): Crucially, within this module, change Byte 1, Bits 5 & 6 to “40 Lane Assist and Lane Change Assist installed (PR-7Y5)”. This step directly impacts the Lane Departure Warning functionality.
-
Module 17 – Instruments: Potentially enable “Lane Assist Installed” in Byte 4, Bit 6 (test functionality before enabling).
-
MMI Activation: Activate the Lane Departure Warning menu within the MMI (Multi Media Interface) system.
Calibration Considerations
Calibration may not be required after coding. The system often calibrates during factory production alongside Adaptive Cruise Control. If a fault code in module 8E indicates calibration is needed, consult a dealership.
Remember, Active Lane Assist is a driver-aid, not a substitute for attentive driving. Always maintain control of your vehicle. This guide, adapted from AudiWorld forum member IKnowHuhA6’s work, aims to simplify the process of locating and coding the Lane Departure Warning module in VCDS for your Audi.
