2009 Focus 1.8 tdci

[RDG1976]

Hi Everyone

New to the site, just after some advice. I have a 2009 1.8 tdci Focus, car drives well apart from when accelerating.

So when I'm approaching a junction or roundabout, where you would usually drop it in to second gear just to keep moving. when i press on the throttle there is a serious lack of power just feels flat. so i drop it into first when moving and have to slip the clutch a little. seems like lagging from the turbo, but im unsure. I'm not able to drive the car in a normal fashion, if you have to pull off quick it doesnt really happen as there is to much lag, so give it a rev and pull off faster the required, there is no middle ground.

Cheers
