Help Needed With Acceleration Judder

[Guest JENKIC01]

Hi guys

 

im new to this forum as recently bought the other half a citroen c3 pluriel.

 

The car runs fine and only covered 16k miles 2003 1.6 auto

 

now the only thing that doesnt seem right is when setting of or reversing the car seems to judder more so when cold and on hill starts.

 

It feels as though the accelerate cable is slack, however i am aware that the peddle is drive by wire or electronic

 

can anyone help as to how i fix this as can be annoying asit feels like the car labours.

 

Also there is a very faint whine/buzz coming from the rear, is this normal sounds like a electric motor.

 

thanks for any help
