I couldn’t find a verified or safe download for a “v42720 psdzdata lite repack” from official sources. PSdZData (used for BMW coding/programming with tools like E-Sys) is typically distributed through paid or subscription-based platforms, and “lite repacks” are often unofficial modifications.
This specific version is compatible with newer BMW "G-Series" models and updated "F-Series" software. Common Sources & Links v42720 psdzdata lite repack download
If E-Sys gives you a version error when trying to read the VCM or connect to the car, it means your PSdzData version is too old for the software currently installed on your vehicle by the BMW dealer. Upgrading to a newer pack (like v42720 or later) solves this. I couldn’t find a verified or safe download
