V42720 Psdzdata Lite Download Install [top] Guide
To download and install v4.27.20 PSdZData Lite, follow these steps based on standard BMW coding community practices:
Official download links for PSdZData are typically not hosted on public websites but are shared via private message (PM) on major forums to ensure users get the latest compatible version.
Request the Link: Visit the PSdZData Full vs. Lite thread on Bimmerpost and post a request for the latest lite version. A long-time community contributor, typically shawnsheridan, will PM you the link.
Alternative Source: You can also check the Bimmerfest software links for up-to-date repository access. Installation
Once downloaded, the "Lite" version (approx. 2.5 GB) is sufficient for VO and FDL coding.
Extract Files: Use a tool like 7-Zip to extract the downloaded .rar archive. v42720 psdzdata lite download install
Locate Data Directory: Navigate to your E-Sys data folder, usually C:\Data\.
Replace Old Folder: If an existing psdzdata folder exists in C:\Data\, delete it entirely. Do not merge the new files with old ones.
Copy New Folder: Move the extracted psdzdata folder into C:\Data\, resulting in the path C:\Data\psdzdata\.
Verify Setup: Ensure the dist folders are present within the chassis folders (e.g., C:\Data\psdzdata\mainseries\S15A\...\dist). If they are missing, create an empty dist folder in those locations.
Configuration: Open E-Sys and verify the data path in Options > Settings matches your installation location. PSdZData Full vs. Lite - Page 66 - Bimmerpost To download and install v4
Step 3: Backup Old PSdZData (Highly Recommended)
Before replacing, rename the old folder:
- Go to
C:\EC-Apps\ESG\E-Sys\ - Rename
psdzdata→psdzdata_OLD_vX.X.XX
This allows you to revert if the new version causes issues.
Step 7 — Post-install checks
- Start the simulator and load an airport included in the PSDZData Lite set.
- Verify textures, buildings, and objects appear correctly and there are no missing files errors.
- Check performance (FPS) and revert or reorder sceneries if you see major issues.
Why Choose "Lite" over "Full"?
The single most important decision during the download phase is choosing between the Full and Lite packages.
- Full Version (~250GB+): Contains the complete SWFL (flash files) for actually flashing ECUs to a new firmware version. This is intended for dealers or users with very high-speed internet and massive storage who need to perform full ECU programming updates offline.
- Lite Version (~3GB - 5GB): Contains all the XML data, ECU diagrams, and diagnostic logic. It allows you to run ISTA+ perfectly for diagnostics. Crucially, Lite allows you to code (using tools like BimmerCode or E-Sys in conjunction with the database). The only thing missing is the heavy payload data for full firmware flashing—which most DIYers never do anyway because it is high-risk.
The Verdict: Unless you are running a dealership server, the Lite version is the correct choice. It downloads in minutes rather than days and installs in a fraction of the time.

Version v4.27.20 – The Time Capsule
This version corresponds to a specific ISTA/P release (BMW’s factory programming system). 4.27.20 is from around mid-2018–early 2019, supporting:
- F-series (1,2,3,4,5,6,7, X1, X3, X4, X5, X6)
- Early G-series (G11, G12, G30, G32)
- i3 / i8
- Mini (F-series based)
Why would someone choose an older version like this? Because newer PSdZData versions may remove support for older ECUs or break certain custom codings (e.g., anti-dazzle high beams, video in motion). This version is a sweet spot: stable, well-documented, and compatible with most E-Sys setups from that era.
What is PSdZData? Understanding the Basics
Before diving into the specifics of v42720, we must understand the core terminology.
- PSdZData stands for "Programmierung und Codierung Daten" (Programming and Coding Data in German).
- It is the proprietary BMW database containing firmware, CAFD (Coding Application File Data), SWE (Software Engineering) files, and bootloaders for every ECU (Electronic Control Unit) in a BMW, Mini, or Rolls-Royce vehicle.
- PSdZData Lite vs. Full:
- Full (v42720_full): Contains everything, including heavy firmware update files (flashing data). Often exceeds 60–80 GB.
- Lite (v42720_lite): Stripped of the large firmware flashing containers. It retains the essential coding data (e.g., .ncd files, .xml descriptors). The Lite version is typically 3–5 GB.
Why v42720? This specific version supports newer G-series software protocols (I-Step updates) and is often required to code recent 2023-2024 model year features, such as Anti-Dazzle high beams, iDrive 8 modifications, or battery registration for new AGM batteries.
