revision on the adaption reset --->Don't need a tool.

With the car off get in, don't put your foot on the brake.
Press the start button once.
Press and hold down the accelerator pedal for 25 seconds.
Start as usual.

Everything will be reset.

I had the same problem, and this worked like a charm. This site has been very helpful thus far.

Cheers!

What start button?
Do they mean turn the key to position 1? Position 2?
How do you do this one time? Do you turn the key all the way (to engage the starter) & then turn it right back off (key position 0) before you let the engine start?

You obviously wouldn't push the gas pedal all the way down for 25 seconds with the engine running........

Inquiring minds want to know!

Your car doesn't have a start button? Must be from Mexico.


I think one push of a start button is one click in an ignition

OMG...not this bull_ _ _ _ again. The only way to reset the transmission is with diagnostic equipment. There is no driveway simple reset procedure for our generation of BMWs.

These silly internet (rumor) reset procedures are just owners that are ill-informed about ATC (adaptive transmission control)...and are unaware that they are only engaging the adaptive sport mode by duplicating the driving style of an aggressive driver...and thus have duped ATC into thinking there's an aggressive driver behind the wheel. ATC selects the adaptive sport mode...and this change in the way the transmission is shifting...makes them believe the transmission has been "reset"...when all it has done is select one of the 3 shifting patterns it would normally select based on the driver's natural driving style (extreme economy (aka granny-toe), economy, or sport mode). The transmission selects one of these 3 by the way the driver is "mashing" the accelerator pedal.

This rumored & false reset procedure, has the driver turning the ignition on (which sets up the modules to read driver input), then mash the accelerator pedal to the floor and hold it there for a few seconds (this suggests that the driver is aggressive)...due to the two previous actions...ATC will select the adaptive sport mode...again, thinking that there's an aggressive driver behind the wheel. If the continuing driving style is not maintained...and the driver is actually a normal or extremely timid driver...then after a few minutes...the shift pattern will change to how the driver is actually driving the car...and can go back into extreme economy or economy mode.

Driver influenced adaptive tranny data isn't stored but renews with each restart. AGS tranny stuff...like how the tranny reacts to wear over time is stored...BUT requires softwear/hardware for a proper reset:


Below is how the driver influenced features of ATC works. The driver influenced adaptation occur each time the vehicle is started and are NOT stored...and the shift pattern is selected by how the driver uses the accelerator pedal and kick-down feature:

I have to admit I fell victim to this "hoax" when I first bought my E38. My transmission has a 'launch' problem after it heats up but when it was new to me I didn't quite realize what was happening and tried this and thought it fixed it...until the next time I drove the car! If only those posts could be DELETED.
