The SIB below is for the 545 model.
The following software errors were corrected with the release of CIP 17.01(Target data Status E060-05-06-500).
Vehicles equipped with 6HP26 up to 4/05, customer complains of harsh downshift. Refer to SI B24 03 05.
Here is the SIB240305 bulletin:
Harsh 2-1 Downshift
E60 (545i); E63/64 645(Ci/Cic) with 6HP26 up to 04/05
Customer may complain of the following:
An excessively harsh 2-1 downshift when decelerating to a stop, or
Transmission "bangs" into gear when accelerating from a full or a "rolling" stop (vehicle did not come to a complete stop).
On a customer complaint basis only, reprogram/recode complete vehicle using SSS with CIP on-line update 17.01, or higher.
Transmission temperature must remain below 50 deg C and trans shifter must be placed in P position prior to the start of CIP programming.
Great info, my 05/05 built 545 has this issue and I'm getting the run around from the dealer I bought the car from. I'm sure if I show him this, he'll say the cars build date falls outside of the SIB dates...but I'll give it a shot.
