Hi guys, newbie here. I would like to confirm that the procedure of inserting the fob and pressing the gas pedal for an amount of time ‘is not RESET OF ADAPTATION VALUES’ is it ?

Resetting the adaptation value of the tranny can only be done through software alterations, isnt it ?

And actually does the gas pedal thing rally solve anything ?

I have transmission faulty 4f8d.

Gas pedal method is a reset of throttle body adaptations.

You can reset the trans adaptations in ISTA.

I would first research the code, many change the fluid

Thanks for the reply. I see. Can i know if there is any harm in me trying the gas paddle method if i get the transmission faulty warning ?

ISTA, i am guessing that it is via external software, right ?

I read around about the code, its either leading to a change of the tranny, tranny adaptations reset or changing the mechatronic seal. I did not find a solid feed back on what was the outcome.

I think i read that the tranny adaptations reset may lead to more issues, i could be wrong.

I recently changed the fluid.

If you changed the fluid register that within ISTA, it might fix your problem as it’s expecting old fluid and adjusts as such.

You can do the throttle adaptation, it won’t mess anything up.

I see. Thank for the feedback. Appreciate it. I will read more about the ISTA.

Is meddling with the ISTA, a part of resetting adaptations ? Trying to get the terms correct.

See if you can do it in bimmercode or bimmerlink, they are apps but you have to pay.

ISTA is a software you get over the internet and buy a cable to use it, but it’s a bit tricky to install but doable

Ok. But i am not going to jump into it at once as i am mot familiar with the car it self.

What i am trying to ask is if, if i meddle with Bimmercode or bimmerlink or ista, and i reset/input the details of the recent oil change, is the processes known as reset of adaptations ? Or resetting adaptations is completely different process ?

In ISTA it’s called fluid change or something like that. I have no experience with bimmercode. At 100,000km I drained my trans and refilled with new fluid and perform fluid reset. It shifted better, next time I may change the filter

Got any more info on the ISTA reset for new fluid?

I've never heard of this but I'm intrigued. I changed my fluid at 95k for the first time and didn't mess with anything in ISTA. Definitely shifts nicely now but I wonder if I should do that anyway?

Do it! The Tcm needs that info for optimum shifting and service life

It’s under service functions, power train

Something like that
