Official download links are generally not hosted on public, permanent sites due to licensing. Instead, they are distributed through enthusiast communities.
Requesting Links: The most reliable way to obtain the specific v4.27.20 files is to request them in established BMW forums like Bimmerpost or CarTechnology .
Version Compatibility: Note that newer versions of PSdZData (e.g., v4.44.31) are typically backwards compatible. If your tool does not support the latest data, v4.27.20 is often used as a stable legacy version . Installation Steps
Once you have the files, follow this standard installation procedure for E-Sys: Prepare the Data Directory:
Navigate to your C:\ drive and create a folder named Data if it doesn't already exist. Inside C:\Data, create a folder named psdzdata. Extract the Files: Open your downloaded PSdZData Lite archive.
Copy the contents of the archive's psdzdata folder into C:\Data\psdzdata.
Crucial: Ensure you do not have a nested folder structure like C:\Data\psdzdata\psdzdata. The final path for chassis folders should be C:\Data\psdzdata\mainseries\... . Fix Missing "dist" Folders:
If your E-Sys "Target" list is empty after installation, you may need to add empty "dist" folders to every chassis subfolder (e.g., C:\Data\psdzdata\mainseries\F020\F020_xx_xx_xxx\odx\dist) . Configure E-Sys Settings: Open E-Sys and go to Options > Settings > Directories. Ensure the "Data: path" is set to C:\Data .
