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:

SUBJECT
Harsh 2-1 Downshift


MODEL
E60 (545i); E63/64 645(Ci/Cic) with 6HP26 up to 04/05


SITUATION
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).

CAUSE
EGS software.

CORRECTION
On a customer complaint basis only, reprogram/recode complete vehicle using SSS with CIP on-line update 17.01, or higher.

Important:

Transmission temperature must remain below 50 deg C and trans shifter must be placed in P position prior to the start of CIP programming.
First off, thank you.

It's amazing that this isn't covered under CPO warranty, that you have to plead for a 'goodwill' case in order to have the software upgraded. Especially since they released this TSB for the same problem.

My appointment is for tomorrow morning. I'm not going to authorize them to do anything other than test drive the vehicle. If they want to charge me for the upgrade, I will go the same route you did. Any advice on that?
