New AT Protocol!
Dear Users,
A premium upgrade has arrived for VAG’s most prestigious diesel segment! We are thrilled to announce that the Bosch MD1CS014 (including gen2) and the brand-new MD1CS064 ECUs are now officially supported on your AutoTuner Tool.
This protocol targets the absolute pinnacle of high-end German diesel engineering: the mighty 3.0 V6 TDI powerplant, widely used across the 45 TDI and 50 TDI ranges, as well as the famous performance-driven Audi S models (S4, S5, S6, S7, SQ5).
Furthermore, this release includes the cutting-edge MD1CS064 ECU, granting you access to unlock and tune the latest mild-hybrid (MHEV) V6 configurations found on vehicles all the way up to 2026 models!
🔒 A highly secure workflow (Mail-in ➡️ Bench): To safely bypass the advanced factory protections on these modern modules, a seamless two-step process is required:
Bench (AutoTuner Tool): Once returned to your workshop, you gain full Bench access to read and write calibrations directly on your workbench with complete peace of mind.
Supported Highlights (3.0 V6 TDI / MHEV Engines):
Audi S & Performance Lineup: S4, S5, S6, S7, SQ5 (3.0 TDI EU6)
Audi Sedans & SUVs: A4, A5, A6, A7, A8, Q5, Q7, Q8 (45 TDI & 50 TDI variants)
