Changed Spark Plug & Coil Pack-But still have missife on Cylinder 2,What Next ?

those just point to the battery being disconnected or going flat

Yea could be 1 option, BUT...

The battery has not been off and is not flat!.. Ive tested battery & alternator and is fine. Im getting different faults arising all the time!!!

[Hurdy]

 An intermittent fault could point to a dry connection in the ECU, a poor wiring connection or a core break inside a wire. Have you disconnected any circuit connectors or wiring recently (or the dealer?)

I was thinking ECU 

I might take it off and send it to BBA for testing and repair, or is there another way to test?

Nothing's been disconnected before the faults occurred

Also my low boost fault i'm thinking could be the vanes stuck in my turbo as everything has been replaced that could be a possible cause!. Ive seen a turbo cleaning set for it?

LOL, that doesn't suprise me one bit. You need to take it to a specialist. Sounds like its under warranty though - good luck.

p.s. the petrol GTi's don't have variable vanes on either K03 or K04 turbos, so unlikely to be that.

If it is registering misfires then there is definitely something wrong!

I took for a blast tonight, and didnt feel too bad. I cant hear the turbo though to be honest with windows up, just alot of engine revving. It feel's like it did before when the DV went wrong!!.

....anyway, got home and sat in it for 2 mintues, and i could feel the engine miss-fire  . It's crap, How the hell can I diagnose a miss-fire with and without my vag com, and VW have it for 4 days and cant find a thing wrong with it.

Now what to do!!

[johnford60]

Someone recommended to change the Fuel pump in the tank!.

So ive done that today, and seemed to go good on the way home. I'll go for a blast tonight and update.
