Cool Pete, keep me posted please.
PeteM:
Spent a bit of time looking at VCDS and popped up to a local mechnic I know and both point to injector, so looking to replace the injector in C2 to solve it. I'm away until next week now so won't get a chance to sort it for a week. Will let you guys know how I get on.

Finally got around to some investigation work.
Light came on solid last night and read the code and still said misfire on cylinder 2
Swapped the coilpacks on 2 and 3 and went out.
Drives better now :confused: and very feint misfire.
Logged blocks 15 and 16 and cylinder 2 had a misfire AND cylinder 3.....ARRRGGGHH
Goes into VW on the 31st so they can check the coilpacks as they are covered by warranty. Though might try and run some cooler grade spark plugs as it's remapped and using standard OEM plugs. I know some say you shouldn't need them but other say you should.
Was hoping for bad misfire on 3 so I knew it was the coilpack.....
Will report back end of the week, hopefully it will return so I can pinpoint the problem.

I think the revised OEM plugs are one grade cooler. (on the Cupra anyway)
I imagine new coils and plugs and the car will be silky smooth again.
Have you used any sh*t fuel recently?

Yes.....had to pop in £10 of standard unleaded at sainsburys and an Esso....had a feeling it might be that so brimmed it with Vpower as usual and will plan better in future and not get caught short.
