Technical Service
PERFORM THE PROCEDURE OUTLINED IN THIS SERVICE INFORMATION ON ALL AFFECTED VEHICLES BEFORE CUSTOMER DELIVERY OR THE NEXT TIME THEY ARE IN THE SHOP FOR MAINTENANCE OR REPAIRS.
SUBJECT
Service Action: Reprogram GM6 EGS on MY'07 E90, E91, E92 Vehicles
MODEL
E90, E91, E92 with N52KP, N51 and GM6 produced from 07/25/06 up to 09/15/06
SITUATION
The GM6 EGS software, as originally installed, may cause an uncomfortable transmission shifting characteristic, mainly, a harsh 3-2 downshift while coasting down to a stop.
Updated GM6 EGS software is available which addresses this situation.
BMW will conduct a Service Action to reprogram the transmission control module on all affected vehicles. With the completion of this campaign, the software in the vehicle's control units will be updated as described in SI B09 05 01 (Coding, Individualization, Programming) Procedure B.
AFFECTED VEHICLES
This Service Action involves 328iA/xiA/xiCA/iTA vehicles with N52KP engines and GM6 transmissions, and 328iCA/xiCA vehicles with N51 engines and GM6 transmissions which were produced from 07/25/2006 up to 09/15/2006.
In order to determine if a specific vehicle is affected by this Service Action Campaign, it will be necessary to utilize the "Service Menu" of the DCS (Dealer Communication System) or the Key Reader. Based on the response of the system, either proceed with the corrective action or take no further action.
The Chassis Number Ranges listed are only for informational purposes and are not to be considered as the only deciding factor.
CORRECTION
Update and recode complete vehicle as per SI B09 05 01 (Coding, Individualization, Programming)
Procedure B using Progman V23.01.00 (Target Data Status E89x-06-09-530), or higher.
LABEL INSTRUCTIONS
This Service Action has been assigned code number 478 After the vehicle has been checked, and corrected if necessary, obtain a label (SD 92-295) and:
a. emboss your BMW dealer warranty number in the middle of the label (1);
b. punch out code number 478 printed on the label and,
c. affix the label to the B pillar as shown.
If the vehicle already has a label from a previous Service Action/Recall Campaign, affix the new label next to the old one. Do not affix one label on top of another one because a number from an underlying label could appear in the punched-out hole of the new label.
