Solution is to reset the TBA ( Throttle body adaptation ) and here is how:

- Put the power on but do not start the engine.
- Floor the throttle for 30-60 seconds
- Keep the throttle to the floor and put the power OFF
- Release the throttle and wait 2 minutes.

During the 2 minutes you should feel or hear some kind of mechanical sound.

That should tell you the reset is complete.

Start the car and go notice that the "lag" is gone. The first 5 - 10 % is now engaging the transmission.

I've done it on my X1 and on the X3 of a friend.

Better this way.

Let me know how that work for you please ...

This should work for any Auto Tranny ( 1 series, 3 series, 5, X1, X3 ... ).

Have a nice day !
