resetting transmission to factory settings E90 330i

nottibimmer · 11-05-2010, 02:59 PM

So I came across this thread about resetting the AT tranny settings and have not been able to find much more information on the topic. It is very interesting so I thought I would try and bring the topic back to life...

Here is the post:

"1. Key in slot, do not touch brake pedal
2. Still not touching brake pedal, hit start button
3. Floor throttle pedal for a good 30 seconds (used my phone stopwatch, it's longer than you think)
4. Still not touching brake pedal, hit start button again
5. Wait 30 seconds, I waited longer actually
6. Start the car normally"

Since I have a 330i and people are mentioning this works on a 330i, I was thinking of giving it a shot. Can anyone tell me what exactly this will do, how it may affect mpg, how it will affect shift points, basically I just want to discuss it and see what people think about this.

Thanks

it is not a myth in the 530 and you have the same tranny. I do this frequently and it is always clear as day the tranny resets.

I recently had been driving in a non-sporty fashion for about a month. I then reset it and driving as usual in DS I noticed the gears were holding the low gear/high revs all the time and that was not happening at all before the reset.

I can only speak to the 5 series but its not a myth here and it is the exact same tranny so I cant see it wouldnt work for u

Anyone tell me what exactly this will do, how it may affect mpg, how it will affect shift points? Or if this does even reset tranny at all, or if it resets something else possibly being confused with tranny, i.e. throttle position sensor, etc?

mfstout · 11-07-2010, 10:37 PM

if im not mistaken you do NOT hit start button, just put fob in, hold accelerator down for 60 seconds, then press start. i dont think revving the engine does anything.

nottibimmer · 11-07-2010, 10:58 PM

Do you know what this process does, ie reset shift points, reset throttle position, etc?

3002 tii · 11-08-2010, 10:53 AM

can you just disconnect battery?

nottibimmer · 11-08-2010, 02:52 PM

I appreciate everyone's input, but can we please keep this thread to a discussion of what the process does and not if the process works, or how to perform the process. I have already pasted a quote on how to perform the process and it is already confirmed that it does do something on at least some BMWs.

What the process does exactly is why I started this thread. If you know what it does, please contribute.

Thanks

first-it simply resets the shift points of the D and DS mode and sets them back to factor setting with adaptions erased. Does not effect speed of shift-our trannys to not have ability to increase speed of shifts as do some models with a "sports" button. So it depends on what adaptions you have/how you have been driving for what effect you will see. If you were a grandpa on the gas for a long time you will notice crisper, higher rpm shifts for example

second-process is press start ONCE-until your SES light comes on and the other lights come on like a christmas tree for a second--then everything will disappear and your ses light will be on. Car is not started obviously.

Hold brake pedal for 25-30 seconds then start the car

If you do NOT have comfort access I am not sure if you have to put the fob in and hit start once or not-I have not put my fob in the ignition since I bought the car. So start for me brings up all the lights if my foot is off the brake.

The important thing is not having the brake pressed ro else hitting start with start the car. I think you put the fob in and press start once without holding the brake to bring up the lights-then hold it down and then hit start

I take it this doesn't work for the 328?

nottibimmer · 11-08-2010, 08:31 PM

I have read in another thread that the sound you think is the tranny resetting shift points may actually be the electric water pump doing a "venting" procedure. This is for venting the system after a coolant change and is an entirely different process then resetting the shift points.

Can anyone explain if these two procedures are in fact mistaken, or if the "brake for 30 second" method stated in the above post may be the actual procedure for resetting shift points, and the "accel pedal for 30 seconds" method was mistaken by everyone all along for being the way to reset shift points? (this does not entirely make sense since the "accel pedal" method is claimed to work for some BMW owners).

Here is the quote from another thread:

there is not "hold the brake for 30 seconds" -

It is hold the accelerator for 30 seconds.

It doesnt make a sound-any sound you hear is coincidence.

nottibimmer · 11-10-2010, 04:23 PM

Anyone have info on this?

what are you so confused about? can you not read and follow a basic thread. They are two totally different procedures, both happen to involve the gas pedal, the similarities end then... get it?

So far your posts have been fairly informative in this thread, not sure why that ended here...
