THROTTLE MEMORY RESET

[G335im]

Try this & see if it works, steps to reset the electronic throttle memory etc, found on another site. If you've been driving like a granny in traffic apparantly your cars memory stores that info & that's how your car reacts to the way you drive. This is meant to reset that;

1) Insert the key & push the start button. (Don't touch the brake pedal & don't remove the key at any time)

2) Press & hold the accelerator down for 10 seconds.

3) Without releasing the accelerator push the start button.

4) Release the accelerator.

5) Wait a full 2 minutes.

6) Start the car normally & drive to see if it's more responsive.

Hmm wonder if this works..

Also found a similar procedure here

****Stay away from your break pedal!****
1. Insert fob into slot (if you have a key, turn it 2 clicks to the right)
2. Press Start/Stop Engine button
3. Depress gas pedal all the way down for ~30s (if you listen, you will hear adjustments)
4. Release gas pedal.
5. Wait about 30 seconds
6. Start car

Wonder if I tried that on my E39?

I am also quite curious about this! The throttle does feel very "sluggish" in response. I have been reading a few threads on the e90 forum and it's divided 50/50 - some say it works and others say it doesn't and it's all in the mind of the other drivers. They say a battery disconnect is also or a better way to do this. Then there's another guy saying that the noise you hear from the automatic gearbox is actually the water pump doing a venting cycle after the throttle has been held down for 10 sec... I don't know. Pity there has to be CDV's, hill assist and adaptive throttle if you don't want it!! :thinking:

Okay, so I just gave it a try - scared a corsa driver or two...

In the garage, ignition on and the throttle in for 5 seconds, ignition off and off throttle for 2 minutes. Started the car and went for a drive to get the engine up to temperature. Didn't feel a difference and then stopped in a well lit parking area. Repeated the steps but held the throttle in for just over 10 seconds. Tried again and I think it's all in the mind, maybe there is a slight improvement in response, or maybe I was just more focussed and inadvertently compensating, don't know.

Is this indeed a legitimate ability to "reset" the adaptive throttle or just a "bullshitbafflesbrains"? I mean even my diesel Isuzu bakkies throttle is more responsive - whenever I go back to driving the bakkie I am revving the engine like a learner driver!

Anyone try this with success? Is there a permanent way around this? Adaptive throttle off!?

I reset the adaptive settings on my gearbox the other day as it was getting "clunky", smoothed it right out.

I reset adaptive settings about once a month on both of my cars, and I can usually feel the differance straight away, not always, but most of the time.

Again, I dont know if reseting the engine adaptive settings if I every REALLY noticed a differance or if it is my pip playing a trick on me, but I swear it works.

I however DID notice a differance on my gearbox after the reset, that I am positive about, its silky smooth again, guess it got used to some rough changes.

 

[Philip Foglar]

With the electronics these days and drive by wire anything is possible. I mostly think it was my mind playing tricks on me, but after the second reset attempt it did seem as though my quicker gear changes were smoother than before - the 1st to 2nd in particular. And it's the normal driving speed type pace, not a "launching" type pull off which I find isn't difficult to do smoothly - just the occasional hint of slipping clutch thanks to the CDV...

Gearbox adaptation reset is not recommended, except after rebuild or valve body rebuild/replacement. Apparently it places quite a bit of stress on the gearbox and causes excessive wear... Thats from what I've read. Also, when you are training it, say the first 1000km after reset, avoid short trips where the gearbox doesn't fully warm up, because then it will learn the cold values and most likely be clunky when warm...

Oh, and apparently worn engine mounts can also cause clunky gearshifts...

Bhawahaha...you nasty dude!

I normally just start gunning the car.....consistently try and keep it above 4 thousand revs...After about 5 minutes of sluggish response the car starts becoming alive. All this "green" and efficiency tech BMW implements....

 

[Philip Foglar]

What's wrong with scaring the odd corsa here or there?

 

[Hellas]

My car is a manual and the reset button has 5% alc per volume... :mmm: JUST KIDDING!!

I'm guessing this doesn't work on 1999-2001 E46's??:hammerhead:

From my reading last night it does seem to be a similar procedure for the E46's - you turn the ignition on and then hold the throttle down for 10 sec, then ignition off. Not sure if you have to wait 2 minutes as well but from what I read it seems to be very close...

 

[Sankekur]

Well it would be kinda hard to reset the throttles on those models since they use cables to control the throttles I think.

 

[Philip Foglar]

It makes sense that it would only be for the drive by wire throttles - found this E46 thread somewhere else: Throttle reset

 

[Sankekur]

I tried the one for the e46 this morning before coming to work, it seems to work but I can't say for sure.

That's the funny thing with mine as well. When I gave it a try on the second attempt it did "seem" to allow for a slightly more responsive throttle, but it was definitely back to normal the next day. And for that matter it may have been the placebo effect as they call it - all in the mind. But from what I have read, it's suppose to be the computer multiplier value or whatever they call it that changes and then affects the throttle response be it cable or drive-by-wire. And from my googling it's present on most modern cars, Mercs, Audis, VWs and etc. Stuck throttle toyodas!

 

[Sankekur]

The main thing it seemed to do was when I pull away from a standing start my car seems to get away a bit quicker as the revs start to climb almost the moment I press the accelerator where noramally there would be a slight lag. But I don't know :dunno: might just be the placebo effect, but the throttle also felt a bit more responsive while driving.

 

[Philip Foglar]

But has it reverted back to normal or still the same? The theory is that it is suppose to gradually adjust to the most typical throttle behaviour that it sees - so unless you're belting around a racetrack all day it is going to tame town the throttle response. But if (and that's a big if) it did change the throttle response on my car it was back to normal the next day. What I noticed was that the throttle seemed more lively on standing start and lower gear changes - 1st to 2nd etc.

 

[Sankekur]

Whether this works would could only really be tested if hook up an oscilloscope to the pedal output and the throttle position sensor, then you could quantitatively determine at least the pedal to throttle response.
