But it does solve the problem. Also I rarely need to put the car into sport mode anymore because the shifts are much better. IF you get a sprint booster read all the threads about installation problems 1st so that you don't do it wrong and set off your engine malfunction light like I did. Still need to get rid of that.

I'm still trying to get used to my new/used 2005 545. There is a hesiitation/stumble coming off the line just as you hit the gas. Car idles fine and has loads of power once the engine begins accelerating. But, it is annoying to feel that hesitation. It's almost as though the accelerator pedal is not attached.....I begin pushing down....and nothing....then as I push further the engine suddenly begins to accelerate rapidly. Makes it difficult for a smooth takeoff from a light. Is there a sensor or solenoid that controls fuel delivery that could be causing this?
I OWN SAME YEAR AND MODEL. HAD SAME PROBLEM. TOOK IT TO BMW DEALER AND DESCRIBED SAME AS YOU. THEY TOOK MY CAR AND RECONFIGURED THE MEMORY PART OF CPU THAT DICTATES TO THE TRANSMISSION. IT TOOK A FEW HOURS BUT CAR DEFINATLEY REACTS DIFFERENTLY NOW. UP SHIFTS AND DOWN SHIFTS IN A MORE LOGICAL PROGRESSION. NOT PERFECT BUT IMPROVED. TECH SAID THEY GET THIS COMPLAINT OFTEN. MY CAR WAS STILL UNDER WARENTEE SO THERE WAS NO COST. CANNOT HURT TO ASK..........................

Reset the transmission, and then get into the habit of doing it once a week! (That's what I do!!) 
I though you got a new tranny?

From all the threads i read so far i came to a conclusion that all 2005 545i have this problem. transmission feels different somehow. i think there is nothing else we can do, just do the transmission reset, software update (which helps too), keep fuel system clean and get used to it.
may be part of the reason is because adaptive transmission is always learning (even after reset) and everyday it feels like a different one. So 25 sec trick every week and it should be better - my opinion

I have a late 2004 545i and was about to post the same sort of issue. A slight hesitation on light throttle...nothing then it picks up when you apply a little more pressure. Very irritating as I like to have a smooth drive when I am in traffic and round town.
I tried the throttle reset but did not notice any difference, maybe I need to go to a dealer to get the ECU upgraded?

I don't know what to say BUT you guys on this forum are AMAZING! I drove my 545i for a year and I did not want to ad a Sprint booster, eventually I convinced myself that this is the way the car accelerates until this morning when I reseted the Tranny. Wow what a difference! It's like I unleashed this wild horse and cannot stop it. Thanks Again....
