Hesitation issues.

[PUZZ]

Hi there,
I have a 4.8i with approx. 7,000 miles on it. I often get some hesitation when starting from a complete stop and also some lag before getting slammed into the back of my seat when trying to get around someone quickly in city driving maneuvers. I also note that sometimes it just doesn't accelerate smoothly - kind of choppy like I have bad gas or something.

What gives?

That's fairly normal for that engine.....put the shifter in sport mode and it's virtually gone........Phil

Yes, it seems to be a transmission, rather than engine, issue.

it is mostly the x drive computer adjusting and analyzing traction. try staying in the throttle more often or feed the gas more judiciously. the more drastic the change the more likely the hesitation. even still i have the same issues from time to time.

BMW just hasn't got it right with the 6-speed automatics.

drive by wire issues... (slow loading right now though)... I hate it too... coming from a '95 truck, the difference is night and day... hell I drive my dad's '02 minivan and the difference is huge... why can't they get it right? I almost gave up on the X5 because I felt the delay was bad during the test drives.

Yep, same problem here. Dealer tells me the transmission is in learning mode while driving, but seems it's a very slow learner - and makes me look like one too! Seriously, this is the worst feature of the 4.8i, and I'm really beginning to hate it after 20,000k's in 10 months.

We drive for 200k's at constant speed using the cruise control. Then we hit the first traffic light, and it thinks my dear old grandma is driving. I press a bit harder, nothing, a bit harder, nothing. Then all hell breaks loose! X5 lurching around like a drunk teenager, kids terrified and the wife screaming at me! All I wanted was something in between...

Sport mode will solve the problem, but plays hell with your fuel consumption. And I really don't appreciate having to change modes just to make a smooth exit from traffic lights - isn't that why I bought an automatic in the first place? Never had this problem with any other car.

I feel your frustration, but can't offer a solution other than clear it's memory (ie. give it a good flogging and tell it who's boss). Might be just my imagination, but sure feels better afterwards!!

You need to do 2 things : (a) put shifter in "DS" (sport) mode, or (b) firmly press gas pedal down, dont hesitate when doing that, show it some assurance in what you do - works like a charm for me !
