New AT Protocol!
The MG1CS031 protocol was highly anticipated. After several months of R&D, we are now able to offer you an exclusive, reliable and fully functional OBD solution. 👀
However, this release does not cover all vehicles equipped with this ECU. The MG1CS031 ECU exists in several sub-variants, integrating different levels of protection.
⚠️ To date, we ensure support for this protocol only for 06N907309A ECUs. These ECUs are installed exclusively on Audi A4, Audi A5 and Audi Q5 models, equipped with a FlexRay architecture.
🔎 Quick reminder: this is an OBD method. Therefore, there is no limitation related to the H80 protection present on the ECU. All 06N907309A ECUs, without exception, are compatible with our method.
🔎 Practical tip: as the engine ECU is easily accessible, its reference is visible as soon as the hood is opened. This makes it possible to ask the customer to check the reference before scheduling an appointment, in order to avoid any ambiguity.
As always, our R&D team is working tirelessly to deliver the most advanced solutions possible. Our goal remains to cover all variants, but the new security measures imposed by manufacturers significantly increase development complexity.
Nevertheless, this protocol already allows you to take advantage today of part of the long-awaited MG1CS031 ECUs. 💪
Thank you for your trust. Your recent positive feedback is a real source of motivation and drives us to always go further.
