If your car is 2020 or older, do not chase the newest version. Stick with v.4.27.20 for stability and free launcher support. Frequently Asked Questions (FAQ) Q1: Can I use v.4.27.20 PSdZData Lite with ISTA+? A: No. ISTA+ (diagnostics) requires its own SDP (Standard Diagnoseprogramm) data. PSdZData is for E-Sys and ISTA-P (programming). However, some users manually copy CAFD files to ISTA’s data folder – this is not recommended. Q2: How do I verify the integrity of my v.4.27.20 download? A: Reputable uploaders include an MD5 or SHA256 checksum file. Use CertUtil -hashfile <filename> MD5 in Windows PowerShell to compare. Q3: Will this data work on a MacBook? A: Only via virtual machine (Parallels or VMware Fusion) running Windows 10/11 ARM. Direct macOS coding is impossible due to Ethernet drivers. Q4: My E-Sys says “PSdZData version mismatch.” A: E-Sys records the version in its registry. Delete C:\Users\[YourName]\AppData\Local\E-Sys\est_softwareversion.xml and restart. Q5: Can I mix v.4.27.20 Lite with a newer full version? A: No. Using mismatched swe and sgbm folders will cause CRC errors during flashing. Keep a single, complete version.
