The Advanced Patch Solution for Resetting BMW 19DA Hybrid EGS Units.

BMW 19DA HYBRIS EGS reset files.webp

This resource provides a specialized patch solution and guide for resetting (virginizing) the EGS (transmission control unit) on BMW Hybrid models, specifically those running the `19DA` software family. This procedure is essential when adapting a used hybrid gearbox to a new vehicle.

What Problem Does This Solve?

The EGS module in BMW Hybrid vehicles is securely linked to the original car's VIN and security data (ISN). When installing a used transmission, this module must be reset to a factory state before it can be programmed to the new car. Standard programming methods will fail without this initial reset. This patch and procedure enable the successful adaptation of used hybrid EGS units.



Supported Hardware (HWEL) & Software (SWFL)

This solution is confirmed to work with the following hardware and software combinations.

Main Hardware (HWEL):
  • HWEL_000019DB_016_016_001
Supported Software (SWFL) for F15 Hybrid EGS:
  • swfl_000019da-000_003_000
  • swfl_000019da-000_004_000
Supported Software (SWFL) for F30 Hybrid EGS:
  • swfl_000019da-000_044_000
  • swfl_000019da-000_046_000
  • swfl_000019da-000_059_000
  • swfl_000019da-000_073_000
  • swfl_000019da-000_083_000
  • swfl_000019da-000_084_000


The Reset Procedure

This is an advanced procedure that involves temporarily patching your E-Sys data folder and using TAL-Processing.

1. Preparation:
  • Back up your original SWFL files from your `\psdzdata\swe\swfl\` folder.
  • Copy the "patched swfl" files from the download archive into this folder.
2. E-Sys Flash:
  • Connect to the vehicle with E-Sys.
  • Go to Expert Mode -> TAL-Processing.
  • Create and calculate a TAL for the EGS module.
  • Execute the TAL to flash the EGS with the patched files.
3. Finalization:
  • After the flash is complete, restore your original SWFL files to the PSdZData folder.
  • Recalculate the TAL and re-flash the EGS with the original, correct software.
  • Perform default coding on the EGS module.
  • Clear all fault codes using ISTA. The EGS is now reset and adapted.


Pro-Tip for Advanced Users

The same hardware (HWEL) listed above may be present in other BMW hybrid models. It is possible to use this patch solution on other models by manually changing the type code in E-Sys and calculating a new TAL based on the patched files. This should only be attempted by users with a deep understanding of TAL-Processing.



System Requirements & Testing
  • Operating System: This procedure uses standard BMW tools, which are tested and confirmed to be stable on Windows 10 LTSC 2019.
  • Required Software: BMW E-Sys, Tool32, ISTA, and a full PSdZData library.
  • Required Hardware: An ENET Cable or ICOM interface.
