Will try this later and report back


ps: shouldn't this be in the Technical Section??

[jimmylad]

done this myself a few times & something does seem to sharpen the car up but.................

I always thought this was for a gearbox reset which some claim cant be done.

Something does happen though.

Didn't seem to make any difference to my car.

Same here, but if some folks with manual cars are also noticing a difference...

My car's only done 10K miles, will it need done? reason I ask is I've often thought in normal D mode pulling away, kickdown and general driving the throtle is slow to react and v.sluggish.......I'll try it later however and report back! also 325i Auto.

[DavS1]

Done it the other day, drove it a few times since....feels like a new car almost! throtle response is 100x better, not slow and lazy like before, car feels like its in M mode, haven't tried it in M yet but can imagine it will be better!

DO IT.

[philreid]

I've had to do it a few times since I originally posted this, but it makes a difference every time. Also did it on my Dad's 330D and it even made his perform better!

I did this today and it DOES WORK, everyone go do it now, trust me, my car lots all its pep well it's back, I read about this last night, today went for a drive and it felt wrong, pulled over followed the steps and instant power, I remembered when I test drove the car it felt so fast, It does again, this site is awesome...

After owning my 330d auto for 2 months and finding it a bit sluggish from standstill and rolling acceleration, i did what i thought was the adaptation reset which did not really make much difference, however after coming across the sequence in this thread i tried it today and it has absolutely made a difference to the way the car responds, much smoother and free flowing and sharp acceleration. I must add though that the adaptation learns quite fast and if you do not drive how you want to drive it will adapt to a lazy setting again very quickly,

A must try if you feel your auto is a bit delayed or feels sluggish

I know this is an old post but I have an 06 330i with 108k and my throttle response isn't lazy anymore. My car would leap forward when I would shift from 1st to 2nd manually. Problem solved. Transmission shifts smooth like its supposed to.

[Alexandru.k_24]

Just one simple question, the accelerator pedal should be pressed with the kick down button or without it? Thanks

[bazz780]

I just press all the way

I've always thought my car was a bit sluggish in the throttle response, especially when in D - and this was confirmed when I drove my Dad's car. Of course, his is a 330D and mine is a 325i so there are going to be fundamental differences since his is a faster car and is also a diesel where mine's a petrol, but I just felt like my car was underperforming.

So I dug around a bit and uncovered this forum post which outlines a process called 'Throttle Body Adaptation Reset'.

I was pretty skeptical at first, but I tried it and I swear it's like driving a new car. The throttle response is much quicker, the car revs a little higher before changing up the gears, and it's altogether a lot more fun to drive.

Of course, I could have just put it into DS or manual mode, but I found that those modes are both more performant now, too.

Have any of you guys tried this? There seems to be some discussion around whether this is a genuinely functional process and whether it's just some kind of placebo - but I swear it worked for me.

Basically the process I followed was:

1. Never touch the break pedal & key remains inserted the entire time
2. Insert key and push START Button
3. Press and HOLD accelerator pedal for 30 seconds (some say 5, some say 25 seconds - I did 30 to be sure).
4. WITHOUT RELEASING THE ACCELERATOR PEDAL, push the START Button
5. Release accelerator pedal
6. Wait full 2 minutes
7. Start car normally

I'm probably going to be at the petrol station a bit more often now, but I feel like the car now drives the way I'd hoped when I bought it.

But maybe it is just a placebo and I've gone mad.

Hey,
I've tried it and i can say it works. One question, how often do you need to do reset it? or does it stay that way?
Thanks.

I imagine the problem is the car adapts to how you drive most of the time, half throttle max, minor adjustments etc, but when you want to push on, it has numbed the response to try and help with MPG.

So unless you reset it and then drive like a maniac all the time, you'll probably have to reset it in the future.

I'll try this on mine and see if it does anything.

I've got a 330i auto, and have tried this procedure before, but it only seems to make a difference for a single ride. I think it forces it to go into a sportier map or something like that, but once you switch off the car it goes back to the way it was before.

What I have noticed, that my car seems to hold on to the 1st gear a little bit longer than I would like and the shift up into second is a little rough, but it is fine and smooth once it's gone into the second and past it. I've also noticed, that the car does take off in the second gear occasionally, making it so much smoother and also faster take off. Sometimes I even force it take off in the second gear, by manually going into second before moving off and then switching back to auto as the car starts moving. Kind off wish it always started off in the second unless I was on a hill.

[palitsyn]

I've tried this procedure again last night. Works for the first ride, but is back to normal the next time you drive. This is what makes me think, that this procedure forces the box to use a certain map.

[Digitalize]

I will add that I did this last night, and I don't see the point really.

Yes the car 'felt sharper', but all it was is the fact the the throttle was more responsive, making the car feel quicker as it was putting on more throttle than before. To me it was just annoying as it made driving with light throttle much harder, and by the end of today it was pretty much back to normal with its numbed feel for the first 1/3rd of the throttle, exactly as I want it.

This helps mine but after a few hours / days driving in traffic it goes back to being sluggish again. Normal I guess, hard driving for a while re-learns again after a while but this is quicker.

[mantis]

has anyone tried DS after doing the reset? or is the reset actually putting the car in DS mode?

[Sambuca1]

Old thread revival....I've tried this method on my 325i auto many times, no change at all....feels exactly the same as before.

That's the problem. If you are all the time driving in traffic and trying not to burn lots of fuel it will re-adapt back to that style. This is why you need mode buttons etc.
