Similar SIB was issued for E90's etc. - SIB 240406

- I think this is for '04+ the facelifted X

SIB 240406 was not for the E90's. It was for some E46, E39, and E85 models and it had nothing to do with harsh 2-1 downshifts.

Here is SIB 240106 direct from BMWNA for the harsh downshift for 4.4/4.8 X5 (N62).


(mgruber ......yup the other two TSB #'s are wrong. My bad and mis-information from Al Gores internet)

-Drive FORWARD (Not reverse, so make sure you are out of your garage before you attempt to do the transmission reset)

Do this every other month or when the transmission start slamming again.

Thanks, much better.....

Will this work for a 2002 4.6i X5 as well?

Where did you get this? Do you have any BMW reference for it? (i.e. TIS, SIB, etc.)

I found this information on page 1 of this trend. So, can this be done for an 02 4.6i X5is?

I have this problem still even after trying the transmission reset and the dealer reflashing. I am going to be taking it back soon and see if I can take someone for a ride and show them how to replicate the problem. I will also print out the information on the TSB#.

Thanks for this information!!

So what's the procedure for a 2006 4.8is? The 30-sec throttle push method or something else?
