M2 your Daily Driver? Reset throttle adaptions!

If your M2 progressively feels more sluggish over time and you DD your car or have spent most of the cars life in traffic, you probably need to reset your throttle adaptions.

Modern BMW's basically use a form adaptive tech that adjusts throttle response to typical/consistent driving scenarios. I'm guessing it's been implemented a bit for comfort and a bit for consumption/emissions.

The main issue with this technology is that the car has no idea on how hard the owner wants to drive on any given day and requires a consistent driving style to update to a new profile.

My typical workday route involves 70% severely congested and claustrophobic traffic. The remaining 30% is instead free open highway. Even in my scenario, where the two driving scenarios are somewhat balanced out, I've noticed that over time the car just doesn't pull that hard anymore.

The fix? Reset throttle adaptions! It takes 5 minutes with no effort at all.

Taken from another thread, the instructions are as follows:

Push Engine button ON (once; do not start engine)
Step on the throttle pedal down (all the way down)
Hold it there for 30-40 seconds
With throttle still down, push Engine button OFF
Release throttle
Wait 2 minutes
Start car normally. Done


I've done the throttle reset for each mode (felt necessary to repeat the above process for Sport+) and the car feels completely healed. Now I can easily do aggressive pulls with responsive feedback without feeling like there's any turbo lag. Just try it out!

Super helpful. Thank you!

How often is this needed? how many miles?

Great post!!!! I have absolutely noticed this. Will try tonight.

I've even noticed that right after you turn on the car, if youre more aggressive with the throttle... Right away, then the car is generally more throttle responsive on that drive ...

I've definitely noticed this on the M2c and my Audi as well. If you drive like a little old lady, they'll start to respond that way. Slower, earlier shifts (the Audi ZF8), general lack of responsiveness (both), feeling boost lag-ish (M2c).

A few hard blasts tends to "reset" things a bit, but in the M2 case, an actual adaptation reset results in a lot edgier, aggressive feel and sound for a while that I really like

Helpful for sure.

The other thing that helps "reset" the adaptive ECU is to take the car to a weekend HPDE/open track event and drive the snot out of it. You'll immediately notice an increase in pep and sharpness on the drive home.

I don't have DCT but wow, automatic transmissions still do this?

Way back in the day I had a 2006 W203 C-Class that had MB's 7G-Tronic auto that I also had to "reset" from time to time. I always felt that the feature was stupid and didn't think it would still be around in 2019 in other formats.

Great tip, thanks! M2c on daily kid duty right now while we wait for wife's car to get registered and it's mostly city stop and go. I was getting her out this fall a bit on the weekends but the weather is turning shite.

Yes. Throttle response is always max in sport plus. Works same in the ZF box too.

BMW advised not to keep resetting throttle body adaptation. Its only meant to be used under certain circumstances.

Can you elaborate on that?

I reset mine per this thread and the car feels blistering fast again... Wonder if there's a way to tune out the throttle adaptation. Sport+ doesn't necessarily fix it. Yes there's sharper response to the pedal but the car started to feel a little "dead". Now it feels quick again.

Yeah, I’ve never seen that driving Sport+ “fixes “ the adaptation softening. I’m in sport+ majority of the time, and a bad commute or 2 in a row will still neuter things. A reset fixes it

Throttle adaptation? OMG

This is a driverís car, the driver should always get the same power response for any amount of throttle asked for by the right foot! Considering which mode it's in of course.

The throttle mode I choose should operate the same way, every time I drive the car.

If Iíve been driving around slowly for a bit, and then I ask for a certain amount of power with a certain amount of throttle pedal input, I should get the power I expect, not less power because of some adaptation that some idiot engineered into the car!

Idiots.

This is so stupid, I canít believe it. Wow.

OP!!! You da man!!!

I just did this and the car feels completely different. It's exactly as you said - it feels like the turbo lag is gone.

I'm convinced that this is 100% psychosomatic, but I'll take the placebo effect all day every day! It's awesome. Thank you!!!
