Finding the correct VCDS security access code for your Audi A4 can be crucial for performing certain diagnostic and coding procedures. This article explores potential security access codes for accessing ABS basic settings on an Audi A4, specifically focusing on module 03. While there’s no guarantee of universal compatibility, this investigation stems from an interesting observation in an EPS installation guide.
Exploring Potential Security Access Codes
An EPS installation guide for a VAG vehicle suggests using security access code 40168 for both steering assist (module 44) and ABS brakes (module 03). This raises the question: could the same security access code work across different modules and even different Audi models?
For instance, on an 8V Audi A4, the security access code 19249 is confirmed to work for accessing basic settings in steering assist (module 44). However, finding the correct code for module 03 (ABS) proves more challenging. VCDS doesn’t offer a helpful hint or “balloon” for this module’s security access code.
Code 19249: A Possible Solution?
Given the precedent of a shared security access code in the EPS guide, could 19249, known to work for module 44, also unlock access to module 03’s basic settings? Online forums and discussions offer conflicting information regarding the effectiveness of 40168 on 8V models, with some reporting success and others failure. This uncertainty makes experimenting with 40168 potentially risky.
Therefore, 19249 emerges as a possible alternative. While there’s no documented evidence of its use for ABS basic settings access on an 8V A4, the logic behind this theory rests on the observation from the EPS installation guide. It’s a novel approach that warrants further investigation.
Proceed with Caution
It’s important to remember that these are just potential solutions, not guaranteed fixes. Incorrect security access codes could potentially lead to unintended consequences. Before attempting any modifications using VCDS, always back up your existing settings and proceed with caution. Consult official documentation or seek expert advice if you are unsure. Further research is needed to definitively confirm the correct VCDS security access code for ABS basic settings on an Audi A4 8V.
