Unfortunately, it seems that this new "trick" will need to become a regular and recurring part of the maintenance process. Here's a second vote for the demise of adaptive transmissions!!!!
I know this is an old post, but I had the same update done at the dealer. Thought it was the $379.25 "transmission software update" they did to my 2005 545... I wish I saw this post prior to paying them to take the 30 seconds.

I have tried this - and thought it made a difference.

Now, I'm not sure what to think.

I recently bought a copy of the E60 service manual from Bentley Publishers. It has a good section describing the function and features of each type of transmission available. In the Automatic Transmission details, it describes a feature referred to as: Adaptive Transmission Control (AGS) According to this, there are 2 maps for each position of the gear shifter (D or M/S) These maps are XE - extreme economy and E - economy and S - Sport and XS - extreme sport. AGS uses these maps to adapt to different driving styles based on several criteria: kick fast (how rapidly you press the gas pedal) Cornering aggressiveness, and braking aggressiveness.

All of this seems to align with what I presumed about the transmission - that it could adapt to my individual driving style - OVER TIME.

The last bit of info - puts that theory in question.

The last sentence states clearly that Driver Adaptation is RESTARTED each time the vehicle pulls away from a standstill.

Has anyone else ever heard this described in this manner elsewhere? Bentley is a respected publisher for such material... but would still like to have some corroborating information on this.

Thoughts?

So who says it's supposed to work on every car? What works on a 2004 545i might or might not work on a 2008 528
