BMW & Mini 2.0T/3.0T Diesel MHEV ECUs Unlocked (DDE9: MD1CS015, MD1CS115)

New AT Protocol!

Dear Users,

We are deploying a massive update designed to drive immediate volume to your dyno! We are thrilled to announce that the latest-generation Bosch MD1CS015 and MD1CS115 DDE9 ECUs are now officially supported in Bench mode on your AutoTuner Tool.

This high-value software release focuses entirely on the latest generation of Mild-Hybrid (MHEV) Diesel powerplants from the BMW Group. It unlocks a massive fleet of 2022 to 2027 vehicles powered by the newest 4-cylinder and straight-six diesel configurations (B47 & B57), as well as the brand-new Mini Countryman (2024+).

💡 Capture a High-Demand Premium Market

Modern BMW Mild-Hybrid diesel vehicles are the ultimate everyday cruisers and represent an ever-growing share of the high-end European car market. This protocol allows you to confidently offer Stage 1 calibrations, massive torque delivery, and optimized fuel economy on ultra-recent passenger cars and SUVs that are often still covered by factory warranties.

🔒 Advanced Secured Workflow (Mail-in ➡️ Bench):

Mail-in Unlock: The ECU must first be sent to our headquarters for a secure hardware unlock by our engineering team.

Bench: Once returned to your workshop, factory software restrictions are gone. You gain unrestricted Bench access to safely read and write calibrations directly through the ECU connector pinout—no physical opening required.

🚗 Elite Electrified Fleet Supported:

  • 4-Cylinder Diesel Range (18d, 20d, 23d MHEV / MD1CS015):
  • BMW: 2-Series Active Tourer (2022+), 5-Series (2023+), X1 (2023+), X2 (2023+).
  • Mini: Countryman 2.0d MHEV (2024+).
  • 6-Cylinder Diesel Range (30d & 40d MHEV / MD1CS115):
  • BMW: 5-Series (2023+), 7-Series (2023+), X5 (2023-2027), X6 (2023+), X7 (2023+).
