Gti 6 problem :( juddering

[Niall]

What did you use to clean the ICV? Also it might jjust e out right nackered in which case no amount of cleaning will help.

Also if you are going to change the plugs i would recomend bosch super 4's used these in all my gti6`s and they are feckin good

Not so sure about super 4s. I've heard of people having issues with coil packs after using them. I swapped my super 4s for just standard ngk and it ran miles better.
