[NEW] CORRECTION
On a customer complaint basis only, reprogram the EGS control module using the "Manual entry"
Important:
It is not necessary to replace the automatic transmission for this type of complaint.
[NEW] PROCEDURE
To reprogram the EGS control module using the "Manual Entry" method:
1. Connect a BMW approved battery charger to the vehicle.
2. Start a programming session, using the latest version of Progman, and select the appropriate series vehicle.
3. Select "Load Software" and answer "No" to the prompt if modules have been replaced.
4. Select: EGS / Programming / Manual Entry from the column on the right of the screen.
5. Enter the programmed and basic numbers from the listings below, beginning with the programmed number first.
IMPORTANT:
The basic and programmed control module numbers depend on the production model year of the vehicle (MY '03 or MY '04) and DME version (MS43 or MS45.1) in the case of the 325i. The vehicle's model year can be easily located in the VIN: the TENTH digit from the LEFT side indicates a production model year (e.g., in WBABW33424 PL29106, the tenth digit 4 indicates MY '04).
6. Enter the new part number of the programmed EGS control unit first, using the Progman screen keyboard.
