DS3 cylinder 3 misfire

[Libby143]

I'm hoping someone can help as my car has been to the garage twice now and I feel like I'm throwing money away.
My DS is a 2012 petrol, and when driving it starts to judder, its fine when in higher gears but its particularly bad when trying to accelerate in second and third gear and often goes into limp mode.
I've had a diagnostic check and its comes back with cylinder 3 misfire.
It had new spark plugs in the last few year's

Hi Libby, have you tried replacing the coil pack in cylinder 3? I had a similar diagnostic message, replaced sparks and just that cylinders' coil pack and never saw it again. Mine was a 12-plate 1.6 120 VTi petrol.
