Fault codes already checked? We can help

If you’ve already retrieved a fault code, researched it online, or been advised of a code by another garage, we can take the next step. 

A fault code provides a starting point, but it does not always confirm the root cause. We carry out structured diagnostic testing to determine whether the issue relates to a sensor fault, wiring concern, software irregularity or an underlying mechanical problem.

For Audi vehicles, we currently list and explain common Audi OBD fault codes to help you better understand potential causes before booking in .

FAQs

What’s the difference between your diagnostics and a basic scan tool?

Many garages rely on generic code readers that only provide surface-level fault information. These tools may display stored fault codes but often lack the ability to carry out deeper system testing.

At VGS Performance, we use dealer-level diagnostic platforms including ODIS, VCDS and Advance Diagnostics equipment, allowing access to detailed vehicle data, control modules and live sensor readings across a wide range of Volkswagen Audi Group vehicles. This enables structured fault investigation and accurate testing, rather than simple fault code clearing

Can you diagnose issues with warning lights or intermittent faults?
Yes. Whether it’s a persistent dashboard light or an issue that comes and goes, our advanced diagnostics allow us to pinpoint the cause accurately, not just clear the fault code.
Do you offer Audi car diagnostics for S-line or RS models?

Yes. We carry out diagnostics on a wide range of Audi models, including S line and RS performance variants.

Using dealer-level diagnostic equipment and manufacturer-compatible software, we can perform in-depth fault diagnosis, module configuration and coding updates (subject to vehicle compatibility) across models ranging from the Audi A1 through to higher-performance vehicles such as the Audi RS6. Please contact us to confirm compatibility for your specific model and year.

Can I book a diagnostic check alongside a service or MOT?
Yes, we can run a diagnostic alongside your scheduled service or MOT visit. It’s a good idea if you’ve noticed a warning light, reduced performance or any electrical issue.
Is a diagnostic check worth it before replacing parts?
Yes. Fault codes alone do not always confirm which part has failed. A proper diagnostic check confirms whether a component is faulty, affected by another issue, or operating outside expected values. This helps avoid replacing parts unnecessarily and ensures the correct repair is carried out first time.
Do you have pages for individual fault codes?

Yes. We have dedicated pages for individual Audi OBD fault codes to to help you better understand what a specific code may relate to before booking in. Each page outlines what the code typically indicates, common potential causes, and why further structured diagnostics are often required to accurately confirm the root issue. For example, you can view our guide for Audi fault code P060900 for more detailed information.
