Is It Normal

[Martin Gillespie]

Hi guys and girls, i have noticed when pulling away i get a slight hesitation,a bit like someting was holding the car back for a split second.

IS IT NORMAL

yeh on mordern autotrans there is a slight delay of a second sometimes a second or two before power is transmitted to the rear wheels when the vehicle is stationary! mine does do this occasionally but not all the time..I think it is to do with the ECT-i (Electronic Controlled Transmission -Intelligence) communicating with the ECU to work out what the driver is intending to do i.e. crusie, accelarate fast etc..

so ounce you dip the throttle i think signals are sent to the ECU with this data and the car works out what the driver wangt from it hence there is a slight pause to gather this data before it moves its to do with the fact that drive by wire is used rather than a cable linking to the throttle opening. dont worry it happens on BMW's, mercs and Audis too.. but if the dalay is severe i.e. 5 seconds or more then you might have to get it looked at hope this helps.

hi

i have to say i have never experienced hesitation once the car has warmed up - however on cold mornings the gearbox is a bit sluggish for 2 or 3 minutes - i have read this is a safety feature of the gearbox therfore normal

No delay on mine to be honest, bearing in mind it does 0-60 in about 6 seconds, there surely shouldn't be?
