around 20 dolla approx each. No point of guess till it gets scanned and log on a diagnostic 1st.

Is it more a hesitation rather than juddering? It sounds like what mine was doing when a coilpack was on its way out.

yes mate it does feel like it wants to go, it does pull still but there a slight juddering, how could you find out which coilpack has had it?

I took it for a blast until the engine light came up and then it told me on vagcom.

Or you could replace all 4 which is the nicer way of doing it.

Expensive way of doing it though, just buy one, and keep replacing it and doing trial runs until you find the bad coil pack
