Jerking and Hestitation at low speeds

Hi all,

A few threads here have discussed the issue of Jerking, Hesitation, OR acceleration delay.

I think it would be interesting to get some numbers that would show how common or uncommon the problem is.

Hope to see many participations.

Thanks!

In order to form an objective view, you should define which engine and transmission you're talking about. This has been an issue, but as far as I know, it's only affected petrol engines.

I think its psychological -the product of drive-by-bit throttle + fuel efficiency maximising transmission program, and the uncompromising("its not me, its the car") driving mindset/habits
After a while of driving around sedately, I wanted to drive sporty again, but I found the car jerking a bit, as the current 'program' it was running (thank you HighlandPete) was for such a response. But as soon as I realized what was happening, I 'got' what the car was doing, and naturally your own behavior 'learns' to play well with the car.
There is no way out, unless you don't want any of the varying trans. programs etc. but that is not really possible with the 'Sport'/'+' settings..
The layers of technology and smart programs can be improved, but the settings are a 'mean'(average) for all drivers to share, there is just no individual adjustability if that is the way to solve it.
Granted, it may be a challenge for someone used to driving a different 'system' to adjust, however it is necessary, or the cars would never improve. To the bmw ppl who perfect this stuff, I think its close to perfect as you can get. The gap lies in we can not all drive like bmw ppl, perhaps they need to dumb it down a bit more.. we are not ready for their systems.

add: I can't find a category to vote, as I can cause the 'problem' when I want to, and can avoid it also.. so I can't call it a 'problem'. It's more like an 'effect'. Because we kind of understand why its there, and I'm not sure making it go away would be a good thing (you might get worse mileage, delayed emergency response etc. -everything is a trade off)

It's not psychological. Unless the dealer re-setting the adaptive portions of the transmission re-set my psyche as well. Because the drive is a LOT better.

All I can say to the above is BS...! I have driven for over 50+ years everything from everyday cars to very high performance race cars and this problem is not normal. BMW needs to address this so that their reputation is not damaged on future vehicles.

I thought about doing the poll per engine type and size. But then I relized I'd have too many polls or too many options. I wanted to make it as smiple as possible, to get a quick snap shot.

But I think you're right, it would be more informative if i did it per engine type.

Maybe some cars do have an issue but I do know that if I am rough with my car's accelerator pedal the car can become a bit snatchy to drive but also if I am gentle with it and feed the power in it's smooth. Same goes for a manual car, if you let the clutch out sharp it isn't going to be a smooth start off or gear change.

Has there been a software fix yet, besides the reboot?
The placebo effect is very subconscious. When brought to our attentive, we find it hard to believe how suggestive we are.

All the experience is perhaps the 'problem', though I wouldn't call it that. You are used to, and 'want' a certain driving feel. But why do bmw make their cars this way? Everyone wants different things. The f10 steering is targeted to the average (more sedate than you) driver. So we could still be talking about this 10, 20 yrs from now, but then there would just be more to complain about. Too bad no car maker makes it the way YOU want it. Get a lotus. Bmw sells to soccer mom now.

I totally agree. BMW needs to get more testing, and programming under their belt to get these issues resolved before introducing the car.

There is one and only 1 reason that BMW is making cars this way. It is because they are being forced too with Regualtions and Rules that they have to meet.......or pay high fines, or be excluded from certain markets around the world. (True...they want the Soccer Mom business as well.)

Case in point. The new flatter nose design of the F10 / F11 (although good looking in my mind) isn't a result of a design theme that BMW wanted to pursue............but rather becuase of European standards now in place that minimize injury when hitting a pedestrian. Now I agree, that is a worthy endevor............but don't blame BMW on it. (Volvo's, Audi's, etc all have this new theme as well....most which are uglier in my mind than BMW.)

The same issues apply to all the efficiency and emmisions rules. Hence, Turbo's, Electric steering, Eight speed transmissions, Direct injection, Alternator clutches, Electric cooling fans, Stop start,.......the list goes on and on. Great technolgy.........but technology that has to rely more heavily on software and programming to run it. BMW would love nothing better than for the new 5 to feel like the car they made 20 years ago. But this increasingly becomes harder to do once you have all these gadgets. I still think they make a great car, the best on the road, but they are falling behind on the software and need to do better.

Sorry..........I will get off my soapbox.

I have found that the jerking issues have largely gone away as the car is now fully broken in (Oct '10 build, 550xi, 6k miles). I do notice, however, that if I am driving at fast/aggressive highway speeds, then come up on slowed highway congestion (which is common in Chicago) then it takes the trans. programming 30 seconds or less to "figure out" that I am in stop/go traffic then seems to adjust to that. Seems reasonable to me that there would be several programs to control how auto trans. should respond.

Good turn out... thanks to all that participated.

Is a trend developing that says you either have this problem or not? And that there isn't a fix for it so far?

let's keep in mind that many people with no problems at all might not feel the need to go online and join a forum that discusses such problems. So, the results don't necessarily mean that most cars sold have a transmission problem.

I think that fact the few say it got better over time is very comforting for the rest of us that have this issue.

Hope to see more votes... and if you got it fixed, please post "how"... if it was through software or by replacing a mechanical part.

Mine was "fixed" by the regional BMW tech with a complete software update, but this was done once before and the fix only lasted about three weeks.
BMW keeps telling me that my driving style could be causing the adaptive tranny to behave this way,

Sorry, I don't.. It was a complete SW re-load.
I was told that it's the latest SW and was released about two weeks ago.

Thanks for sharing FG... I think I'm going through the same process you've been through.

First time, my dealer did the throttle Adaptation reset, and the car was smooth for about a week. Then the same issues came back.

The second time, he uploaded the latest software for transmission. It was the latest version from BMW (ISTA/P 2.41.1), and was meant to resolve these throttle issues. It made things perfect for about 3 days, then it went back to it's old ways.

How long has it been since you got it fixed?

Interesting I have stumbled across this - I was test driving the 520d F11 and I had the same complaint. Putting it into sports mode will help.
