This package contains two complete firmware datasets for Audi MIB2 MHS2 infotainment units, extracted from original SD update media. Both regions – EU (ECE) and US (NAR) – are included with full metainfo2.txt manifests and all update61858-xxx.dat segments.



The pack is intended for professional retrofitters, ECU engineers, and advanced users who need reference firmware files for analysis, recovery or development work on MHS2-based head units.

What’s inside
Each dataset is a direct dump of the original SD card structure for the corresponding part number:

• metainfo2.txt – full update manifest with MU version, variant, market and model information.
• update61858-000.dat … update61858-50x.dat – segmented firmware blocks used by the SWDL/update process.
• Main component folders (examples):
  • FC1L42xE, FC1L49xE, FC2L37xE
  • GPSReceiver, INIC
  • LTE-ALS6 (ECE) / SXMRReceiver (US)
  • MCM, SpeechAppRes, SpeechRes
  • TNRREF and other resource/configuration folders
• EU and US structures preserved exactly as on the original media (no repack / recompression inside each folder).

Approximate sizes (unpacked from archives):

• 4M0906961CC-MHS2_ER_AU_P2035 – ~3.8 GB
• 4M0906961CD-MHS2_US_AU_P2037 – ~2.4 GB

Typical use cases

• Studying the layout and file structure of Audi MIB2 MHS2 firmware (Delphi platform).
• Preparing region-correct firmware media for ODIS-E or engineering tools (with your own official infrastructure).
• Comparing EU vs US datasets (P2035 vs P2037) for coding / feature research.
• Having a clean reference set when recovering or reworking bricked units.

Compatibility notes

• Designed for Audi vehicles using MIB2 High Scale MHS2 head units with part numbers around 4M0 906 961 CC/CD (e.g. Q7 4M, A4/A5/Q5 B9 and related platforms – verify by your VIN and PR-codes).
• Datasets are region specific (ECE vs NAR). Flash only firmware that matches your hardware, market and feature set.
• No activators, FEC/SWaP keys, map content or component protection tools are included – this is firmware only.

Important

• This is not a plug-and-play SD card image. It is a raw file set intended for experienced users who know how to build proper update media and work with MIB2 in engineering mode.
• Incorrect flashing can permanently damage the unit. Always make full backups and use professional tools and power supply.
• Use at your own risk. The pack is provided for educational, diagnostic and development purposes.
