The Lane Assist feature on some MY2016 vehicles can feel underwhelming, often oscillating between lane lines. A simple VCDS tweak to the A5 control module can significantly improve this by enabling Adaptive Lane Tracking.
This enhancement is achieved by modifying the Intervention moment adaptation channel. The default setting is typically Late. However, selecting either Early (setting via menu) or Late (setting via menu) using VCDS (specifically, SA 20103) unlocks a new option: Adaptive lane tracking within the Lane Assist menu.
Choosing the Early setting within VCDS effectively activates Adaptive lane tracking. This results in a noticeable improvement in lane keeping performance. Instead of bouncing between the lines, the system actively centers the car, providing a more refined and confident driving experience, akin to autopilot.
With the menu option enabled, you can easily switch between the standard and adaptive lane tracking modes without needing VCDS. This allows you to experience the difference firsthand and choose your preferred setting.
This modification may be limited to MY2016 vehicles with specific A5 module versions. For instance, a Canadian MY2016 Golf R with the Technology Package (equivalent to the US Driver’s Assistance Package) and an A5 module part number 5Q0-980-653-G successfully enabled this feature. Conversely, a MY2017 model with the newer frameless rearview mirror and a different A5 module (3Q0-980-654-G) lacked this adaptation channel. The newer module has significantly fewer adaptation channels, limiting modification possibilities.
This VCDS tweak offers a substantial improvement to the Lane Assist system in compatible vehicles, providing a more stable and centered lane keeping experience. If you own a MY2016 vehicle, using VCDS to enable Adaptive Lane Tracking is worth exploring.
