2007-2010 X3 Automatic Transmission Problem Master Thread!
I'm making this a sticky and merging all new AT threads from the main page into this one (I can not move older threads into this one because it will insert the previous messages above/before this post).
Thanks to AzNMpower32 for this summary:
The problem: A portion of 2007-08 X3s built between 9/2006 and 11/2007 my have possible faulty transmission software programming. This affects X3s equipped with the 6-speed automatic gearbox. The gearbox may fail to respond to throttle inputs, fail to engage a lower gear, or downshift very roughly in normal Drive mode. The problem is not exhibited in manual mode. Cold temperatures may or may not make the shifting quality worse.
The BMW fix There is a software update, this is the latest release as of 10/07
Please post all future complaints and/or attempted resolutions on this thread! Thank you.
This Service Information bulletin supersedes SI B24 08 07 dated May 2007.
GM6 - Various Transmission and Driveability Complaints MODEL
E83 (X3) with 6L45R (GM6) automatic transmission produced from 8/2006 up to 10/2007
The customer may complain of transmission shift quality or driveability issues, as described in the situations below:
1. There is a delay in throttle response through the 1-2 upshift when accelerating from a stop.
2. There is a lack of power or hesitation when reapplying throttle, during either a 4-3 or 3-2 tip-in downshift. This may occur after slowing with a closed throttle.
3. Harsh downshifts when slowing on a roadway with a rising gradient (EGS is in a hill program).
EGS software calibration DME software calibration
In the event of a customer complaint, reprogram the EGS using only Progman V27.02.00 or higher. The latest X3 EGS software may be identified as: 0489RZ0RS450 R0FN10 using the following diagnosis path:
Control-module functions / EGS transmission control Diagnosis requests / Status, data reference
It is important that the DME is also at the latest software level. Refer to SI B12 17 07 for more information concerning the DME software identification and improvements.
DO NOT perform the transmission adaptation under Service Functions, as prompted on the Progman screen. This test module is not functional and will be removed in a future DIS DVD release.
Always refer to SI B 24 11 07 for more information regarding GM6 transmission terminology, adaptation functionality, and adaptation procedures. Important notes:
* The transmission must be in the "Park" position, otherwise the programming may abort with the following error:
EGS –Diagnostic trouble 2089 (COAPI) - Programming mode changeover faulty
* Only use an approved BMW battery charger set to PS (Power Supply) mode and properly configured for the applicable battery AH rating.
