The Delphi and Autocom 2021.11 software release (specifically the "C4B" or similar versions) is a popular update in the automotive diagnostic community, known for providing modern car coverage for older VCI (Vehicle Communication Interface) hardware like the DS150e or CDP+. Key Highlights of the 2021.11 Release
Modern Vehicle Coverage: This version typically includes car and truck databases up to 2021, making it a "sweet spot" for technicians who need to work on newer models without upgrading to expensive subscription-based hardware.
Feature Rich: Beyond standard fault code reading, users frequently utilize it for advanced service tasks like VANOS resets, fuel pump pressure checks, and throttle body adaptations.
User Interface: Delphi is often cited as having a more intuitive, structured layout for daily service tasks compared to the classic Autocom interface. Common Discussion Topics in the Community Community posts on platforms like MHH Auto often focus on:
Installation & Activation: Since this version is frequently shared via Google Drive, many posts deal with bypasses for "Hardware ID" (HWID) activation or resolving "Unknown VCI" errors during firmware updates.
Firmware Matching: For the software to work reliably, the firmware on the physical VCI (e.g., version 1622 or 3201) must be compatible with the 2021.11 software build.
Troubleshooting: Users often share diagnostic logs to solve specific issues, such as blinking check engine lights after DPF/EGR deletes that show no DTC errors.
