Can someone in a DSG try and fool the box and see if the delay is noticeable?

You mean by accellerating hard and then dropping a gear :shocked:
Would you do it with a manual? :undecided:

I'll stick with a 400ms unexpected DSG shift as even a manual gearbox change would be longer than 0.4 of a second. :wink:

R32UK, I hope you never break your left leg.   You'll wish you had DSG then.  :tongue:

I still think there is a slight movement in the left paddle which would explain a sensor for the down-change - which would make sense!

Can anyone have a go and comment?

doesnt the computer preselect the gear down under heavy braking?

this seems sensible, as under hevay acceleration it pre selects the gear up?

i think its vice versa where the 400ms comes into it, eg hard brake gear up, hard acceleration gear down.

does this make any sense?

....I did a series of emergency stops recently (on purpose to test my brakes), in M-mode (Manual on DSG) and the gears did not automatically drop down!! She will in D and S modes of course.

No matter hard I accelerate she doesn't change gear in M-mode until she's into the red zone (as I remember) - I usually change gear at around 5,000 revs max.

you've totally misunderstood my there red, i did'nt say it would downshift or upshift, i simply stated that i thought the box would pre-select the gear down rather than the gear up under heavy braking in preperation for a downshift.

If I come up to a junction in M mode and I forget to change gear, the computer changes down to 1st. Must be different under heavy braking.
