This article explores potential VCDS modifications for the Audi A3 S3 8V platform, specifically focusing on initial findings from a base 1.2T model. While this particular vehicle had limited optional equipment (Xenon headlights, rear LEDs, and Audi Sound System), some interesting modification possibilities were discovered using VCDS 12.12.
Decoding the 1.2T’s Control Modules
An autoscan of the vehicle revealed the following modules: Engine (01), ABS Brakes (03), Auto HVAC (08), Central Elect. (09), Airbags (15), Steering wheel (16), Instruments (17), CAN Gateway (19), Door Elect, Driver (42), Steering Assist (44), Door Elect, Pass. (52), Xenon Range (55), and Information Electr. (5F). Several fault codes were present in the Engine and ABS modules, likely due to a previously attempted external chip installation.
Promising Discoveries: Torque Steer Compensation and Tire Diameter Adjustment
Despite the limited modules and the lack of English labels in VCDS 12.12, two key findings emerged:
-
Torque Steer Compensation: A setting within the system suggests the potential to enable torque steer compensation. This feature could be particularly beneficial for tuned vehicles with increased power output. Further investigation is needed to decode the specific options and confirm functionality.
-
Tire Diameter Adjustment: An option to adjust tire diameter was also discovered. This functionality allows for compensating for variations in wheel and tire sizes compared to the factory specifications. Again, further decoding of available options is required.
Unanswered Questions and Future Exploration
Due to the challenges presented by the German labels and the lack of a comprehensive label file for module 09 (Central Electronics) in VCDS 12.12, determining the feasibility of enabling turn signals in the LED strip remains unresolved.
Furthermore, many anticipated modification options were unavailable due to the absence of corresponding hardware in the base 1.2T model. Features like lap timer, mirror dip, fog lights, and start/stop functionality were not present.
Looking Ahead to the 1.8T
Future investigations will focus on a 1.8T model, which is expected to offer a wider range of modification options due to its higher trim level and potentially different module configurations. This will allow for more comprehensive exploration of the Audi A3 S3 8V’s VCDS modification potential. Stay tuned for further updates.
