I'd like to know too :fencelook:

Found this amongst quite a few, question now is which one :=)::=):

1. Get in your car, it doesn't matter if you close the door or not.
2. Turn the key to the on (not start) position, the position just before the starter turns over. BMW: press start button – foot off brake - all idiot lights on.
3. Press the gas pedal to the floor with the key in the "on" position. BMW: All idiot lights on.
4. Hold the pedal to the floor for five seconds, then turn the key back to the "off position". BMW: foot off brake press start button - all idiot lights now off (don't remove the key), then release the gas pedal.
5. Wait a full 2 minutes for a full electronic alignment. Don't remove the key.
6. Start engine, drive the car, notice the difference.

Or:

1.turn key to on position[not start] position,just before the starter turns over.
2.press accelerator pedal to the floor,with the key in the on position.
3.hold the pedal to the floor for 5 seconds,then turn back key to off position [dont remove key] then release accelerator pedal.
4.wait for 2 minutes for full alignment.
5.then drive off as normal.

Or

1 Place key in ignition and turn to detent 1 and count for 10 seconds ( only postion 1 do not start the engine. )
2.Turn key back to 0 postion and count for another 10 seconds
3.Now turn the key all the way to detent 3 to start the engine

Or

SUBJECT M54 EDK Throttle Adaptation Procedure
MODEL All with M54/MS43
SITUATION The EDK (electronic throttle control) adaptation must be reset after a new engine control module, or a new EDK unit is installed.
PROCEDURE The adaptation process takes approximately 20 seconds to perform. If the adaptation process is not performed, the vehicle will not start, or run in "fail-safe" mode.
If the vehicle does not start, or runs in "fail-safe" mode after replacing the DME or EDK, perform the following procedure:
1. Turn ignition ON (KL15) for 10 seconds. DO NOT ATTEMPT TO CRANK / START THE ENGINE.
2. Turn the ignition OFF for 10 seconds.
3. Start the engine.
WARRANTY INFORMATION
For information only

or

First, with the key removed, sit in the driver's seat and insert the key.
Turn the key to position "2". Position "2" is one position before the car engages and starts.
Wait 10 seconds and then turn the key back to position "0", which is the initial position.
Once again wait 10 seconds and then start the car up.
You should now have your throttle response reset and your driving pattern from this point on
will dictate how your throttle response adapts.

A couple say the same thing - just the key and no loud pedal, so I guess it may be a trial and error thing unless anyone has better ideas? :fencelook:

thanks @graan13 i think that answers the questions above lol

The main thing here is to find out if the gearbox does have Driver Adaptive Electronic module installed.

I did this on my Zed and it worked. no need to hold down the accelerator though.

"First, with the key removed, sit in the driver's seat and insert the key.

Wait 10 seconds and then turn the key back to position "0", which is the initial position.

This was what I did and it worked.

I tried two of them, using the 2 keys of the car. The one that seemed to change the pick up and throttle response and gear changes the most was the one that you turn key, count 10, flatten loud pedal for 5, turn key off for 10 and leave for 2mins. I noticed it straight away. I will redo the other key this eve just doing the key on, hold 10, key off and hold 10 and leave. Will report on that one and compare, but definitely the first one worked and that is on a 2002 330i auto individual. Car has 251k km's and don't think its ever been done before - certainly not whilst I have had car!

This is not a gearbox adaptation reset. Gearbox adaptation reset should only be performed when the valve body gets replaced, otherwise you might see an improvement for about 1000-10000km (combined with accelerated clutchpack wear) and after that it will never settle to a good state again and shifts will become harsher.

What this does is only reset the throttle position calibration data for the engine, but since the gearbox uses the raw throttle position data, doing this reset will change how the engine interacts with the with the gearbox, since the gearbox adaptations are based on throttle position.

So is it a good thing or not to do?

Hi Guys,

I found this quiet interesting and haven't seen this on our forum yet. Sorry if i missed it or re-post.

this is basically to clear driving style memory. It should work on all auto cars that have Driver Adaptive Electronic modules

Steps:
push in your key
press start button without pressing the brake
all dash lights should come on
press in your accelerator peddle right down to the floor
hold it in for 5 seconds
with your foot off the break press the start button again, all dash lights should go off
do not remove the key
now let go of the accelerator peddle
do not remove the key for 2 minutes (nothing less

after 2 minutes it will have reset.

Start the car and take it for a drive :rollsmile:

i actually noticed a big difference on my 330d. It feels more sharper when changing.

Its good to do this if you use your car as a daily then decide to go on a track.

Do this at your own risk. Im just sharing information i came across.

Sorry for posting on this old thread... But want to try this tommorow...

I see some keep the pedal in for 30seconds...

1. Insert fob into slot (if you have a key, turn it 2 clicks to the right)
2. Press Start/Stop Engine button
3. Depress gas pedal all the way down for ~30s (if you listen, you will hear adjustments)
4. Release gas pedal.
5. Wait about 30 seconds
6. Start car

Does this work, making gears smoother and change quicker...
