MAN VDF/CDF Collection is a structured library of MAN Truck & Bus datasets used by workshop
software (MAN-cats II/III/4 and related utilities). Files with extensions .VDF (Variant
Definition File) and .CDF (Calibration/Configuration Data File) describe ECU variants,
coding options and parameter values for engines, chassis and body controllers.



What’s inside

• A curated folder of VDF/CDF files (sample names: BR070706, L05X6178, L21XB232, L2654338, etc.).
• Covers typical MAN modules (e.g., EDC/ME for engines, ZBR/FFR/body, ABS/ESP) across multiple model years.
• Consistent naming so you can quickly match the dataset to the vehicle’s option code or ECU part number.

How workshops use these files

• Identification: load a VDF to map variant/coding options during diagnostics.
• Parameterization: apply the correct CDF to set legal parameters and vehicle equipment.
• Flashing & repair: pair the right dataset with the ECU when replacing or reprogramming hardware.
• Documentation: archive the original dataset by VIN and job number for traceability.

Best practices

• Always match the dataset to VIN, ECU family and emission level. Using an incorrect file may lead to malfunction.
• Back up the current configuration before any change; keep a clean “as-found” copy in your job folder.
• Use only with licensed workshop software and follow the OEM service information for procedures and safety.

Compatibility & minimum requirements

• Dataset files are compatible with MAN-cats tooling that supports VDF/CDF formats.
• Tested on Windows 10 LTSC (2019); also managed on Windows 7/8/10/11 (32/64-bit).
• Suggested PC: dual-core CPU or better • 2 GB+ RAM • 500 MB free for archives/logs.
