C4gp 1.6hdi egs6

Unread post by Jakedarrenhughes25 »

Wondering if anyone can help, bought my first grand picasso 2009  it's a 1.6hdi with the egs6 box only had it 6 months but it's developed a judder when setting off only when cold once warmed up it goes away and goes through gears spot on no hesitation, (if I let the car run for 15mins before I need it it doesn't do it at all) , hoping this isn't the clutch or dmf car has done 98k loads of service history from Citroen themselves, read some posts it could be injectors but they seem fine all engine mounts have been changed in my ownership plus fuel filters etc, I have read possibly could be egr or dmf and clutch I don't know enough about these cars to set to on it. Any advice would be great thank you ☺️

Welcome along.

At 100k it's likely to be the clutch if there's no history of it being changed. You could try the reset procedure which is simply to accelerate hard from stationary till it changes up to 3rd a few times. This might improve it a bit, but you should probably prepare for new clutch...

AHH 😖 when you say accelerate hard are we talking full throttle ?? The clutch doesn't slip atall in any gear, thankyou
