Okay, heres the deal. I was driving my friends 2002 325i 4 door auto, it had the steptronic in the middle, but not on the wheel. Anyways...I was racing him through this gated area, and it was driving real nice, but then I was like "ohhhhh", and pushed the pedal down to the bttom, and there was this little button under the pedal on the ground, and if you pushed the pedal down and pushed the button on the floor, it accelerated real fast, almost like a boost. strange......I had never seen or felt such a thing. Any opinions or comments?

"You gotta fix the nut behind the wheel before you fix the bolts on the car"
its the kick down putton. your car should have it too. i have one and my car is an 87 325. what it does is, to give u a boost it will put u in 3rd gear(the car will accelerate) and for the automatic tran to shift up you have to lay off the gas a litttle and then it will shift. pretty sweet. check in your bmw manuel. it will explain it much more clearly than i can. peace out
wait, were you in 3rd in steptronic mode or in auto mode? if you were in steptronic then it wouldnt have kicked down for you. the only thing i can think of is that the new electronic throttles kinda advance the timing slightly at full throttle to take full advantage of stuff like double vanos, but i could be way off, maybe TECH has an explanation. i'll move this to e46 for now.
There should be a kickdown swtich for any auto bmws.. (as far as i know of).. it helps makes the engine revs higher and therefore changes the gear later.. it will also drop the gear when neccessary.. I had it on my previous auto transmission, (1992 318i M40).. It works great with the S-mode, as it will rev till near red line before shifting gear.
My dad's W124 Mercedes 260E also has a kickdown switch.. you can feel a click when u press fully..
if you cant feel it, the switch might be gone (due to wear and tear).. it cant click' anymore, u can get it replaced easily..
