Bosch MD1CS004 ECU Tuning & Remapping Guide

New AutoTuner Protocol Update!

The OBD protocol of the Bosch MD1CS004 ECU for 2.0L TDI VAG engines benefits from new improvements. 🔥

🎉 About the H80 hardware: some versions can be handled in OBD mode, as this method uses an approach specific to the VAG manufacturer. However, the BENCH method relies on a specific Bosch service mode, directly tied to the ECU. Therefore, an H80 ECU cannot be handled in BENCH mode, but might be handled in OBD mode.

Better coverage: The protocol now supports a greater number of Cboot versions. As a result, new VR files have been added and several corrections have been made for even more complete coverage.

We have also developed a better detection for VAG group ECUs, which allows you to know right from the identification if your ECU is supported.
New versions of some ECU references have been introduced by VAG. Those are not yet supported and are identified as Gen2 (for example: MD1CS004 Gen2).
