G30 8HP50 EGS Units Reset.webp

This resource provides a complete patch and a detailed step-by-step guide for resetting (virginizing) the ZF 8HP50 transmission control unit (EGS) in BMW G30 models. This procedure is necessary when adapting a used gearbox to a different vehicle.

What Problem Does This Solve?

The EGS module in the G30 is locked to the original vehicle's security system. When installing a used unit, it must be reset to a factory state before it can be programmed to the new car. This "2ab2 patch" solution utilizes a multi-stage process involving E-Sys and Tool32 to securely virginize the module.



Supported SWFL Versions

This patch solution is designed for the `2ab2` software family. Your EGS must have one of the following SWFL versions:
Code:
swfl_00002ab2-030_034_001
swfl_00002ab2-030_034_002
swfl_00002ab2-030_037_002
swfl_00002ab2-030_037_003
swfl_00002ab2-030_043_001
swfl_00002ab2-030_044_000
swfl_00002ab2-030_055_000
swfl_00002ab2-030_057_000
swfl_00002ab2-030_058_000
swfl_00002ab2-030_059_000
swfl_00002ab2-030_063_000
swfl_00002ab2-030_066_000
swfl_00002ab2-030_067_000


The Step-by-Step Reset Procedure

Follow these steps carefully. This process involves modifying your PSdZData folder temporarily.

Step 1: E-Sys - Initial Flash
  1. Open E-Sys and connect to the vehicle.
  2. Go to Expert Mode -> Tal-Processing.
  3. Load the TAL named `egs tal-step1` provided in the patch archive.
  4. Execute the TAL to perform the first update on the EGS.
Step 2: Tool32 - First Reset
  1. Open Tool32.
  2. Load the file: `gszfb1.prg`.
  3. Find and select the job: `steuergeraete_reset`.
  4. Run the job to perform the reset function.
  5. Close Tool32.
Step 3: E-Sys - Patch Flash
  1. Go to your PSdZData folder: `\psdzdata\swe\swfl\`.
  2. Copy the "patched swfl" files from the `2ab2-patch.zip` archive into this folder, replacing the original files (always make a backup of the originals first!).
  3. Go back to E-Sys and load the TAL named `patch tal-step2`.
  4. Execute the TAL to reflash the EGS with the patched files.
Step 4: Tool32 - Second Reset
  1. Open Tool32 again.
  2. Load `gszfb1.prg` and run the `steuergeraete_reset` job one more time.
  3. Close Tool32.
Step 5: E-Sys - Finalization
  1. Restore your original SWFL files to the `\psdzdata\swe\swfl\` folder.
  2. Go back to E-Sys and load the TAL named `original tal-step3`.
  3. Execute the TAL to reflash the EGS with its original, correct software.
  4. After the flash is complete, code the EGS with the "Code" button to apply the vehicle default settings.
Step 6: ISTA - Final Checks
  1. Connect with ISTA.
  2. Delete all fault codes from the vehicle.
  3. Find and close the "transport mode" if it is active.
  4. The gearbox is now fully reset and adapted!


IMPORTANT: Recovery Procedure

The patch archive includes "2ab2 multi prog recover" files. These are for use with universal programmers like Multi-Prog, etc.
If your EGS loses communication during the process, you can use these files to recover the EGS on the bench and then restart the reset procedure.
