no need to come off the throttle. just blip it. by blip i mean a slight, quick press. a double-blip would be a slight, quick press followed by a slight quick up and press.

button? if you mean "kickdown" it's not a button but a throttle point. if you mean that "area"/"almost click" you get when you press it all the way, i think it's just the way the throttle fits with all of the cables/linkages behind it. i don't think it's an actual button is it? i may have to go look behind my pedal.

ok, well what do you know. there IS a button...

my guess is that it's some sort of feedback for the DME letting it know that the pedal is completely pressed. anyone else have any information on it?

Hmmm I need to get my 'blipping' sorted as that never works for me, or at least not to the point I could do it an expect a change down. It all feels a bit odd, but that maybe the floor mounted accelerator pedal.

I'd never though but you might be right that its the butterfly on the TB not a button. But it does seem to make a difference what ever it is. - Lol..! Sorry was posting at the same time as you. So there is a button...??

yes, and according to the parts guy at a local stealership, that's the "kickdown switch." i always assumed kickdown was the point on the throttle where there's a little more resistance. i never thought there was an actual "switch" as well. so i guess maybe when you hit resistance on the pedal OR when the DME detects the switch has been actuated, you've hit "kickdown" and it does a shift.

yes, kickdown switch (#6 on the diagram):

Well there you go, So what on earth does it do??? I know it changes down, but will it change to any gear to get to a particular RPM? It also seems to change how long it will hang onto a gear for.

again from my manual (or manuell in porsche-ese):

Kickdown
The kickdown function is active in selector lever position D, even if you temporarily change to manual mode M using the toggle switches on the steering wheel.

For optimum acceleration, e.g. when overtaking, depress the accelerator pedal beyond the full-throttle point (kickdown).

The transmission shifts down depending on the speed of travel and the engine speed.
Upward shifts occur at the highest possible engine speeds.
These gear-changing speeds remain active until the accelerator is released to approx. 80% of the wide open throttle position.

Great, now to practice my 'blipping'...

Thank you.
