The Ross-Tech videos provide a helpful guide for conducting brake system tests using VCDS. While brake systems may vary slightly between models like the 2005 Golf and Passat, the general testing procedure remains consistent. The VCDS system function test focuses on verifying the functionality of the brakes and related components.
The test can be likened to navigating a crowded parking lot. Imagine searching for a parking space, making a U-turn, and then straightening the steering wheel once aligned with the desired spot. Similarly, the VCDS system requires a specific driving maneuver to complete the test. Once the steering wheel is straightened after a turn, signaling the completion of the maneuver, the warning light should extinguish, indicating a successful test.
Completing the test can be challenging, often requiring patience and persistence. Driving in circles, figure-eights, and various other maneuvers might be necessary before the system registers the test as complete. In one instance, after numerous attempts, success was achieved on a U-shaped road. Upon straightening the steering wheel after navigating the curve, the warning light finally turned off. Identifying a suitable location for conducting the test simplifies future procedures. Knowing the specific requirements and having a designated testing area can save time and frustration.
