It was a used one that went in Dan. As far as I know new injectors are £100+ each??

Right, bit of an update.
After fannying around getting refunded for the mismatched ebay injectors, I went to pick up a set in person from a local VAG breakers. They initially wanted 120 quid but I got them for 80.
I sent these to Steve Biggs aka Mr Injector (not sure if he's any relation to Ronnie) on the back of @Tfsi_Mike's advice. A shade over 100 quid and a few days later I received my refurbed injectors complete with new seals and a data sheet showing before and after flow. Job's a good un.
I got these fitted at Statller along with an RS4 fuel return valve (made sense to stick one in while the inlet mani was off as I'll be going k04 in the future).
So, after six days of varied driving all seems well. Although I'm not taking the absence of misfires as proof of the fix (being so sporadic anyway) there are a couple of improvements I've noticed. One is that the car turns over in the morning with much less drama; it wasn't terrible before but it did cough into life a little bit on a cold engine. This could indicate that an injector that was causing the misfire might also have been causing a slightly rough startup. The other is that the tinkling/jangling noise I assumed was a loose wastegate is now gone. Apparently this could have been caused by the standard return valve. Who knows. But it's gone.
Big trip to Wales is now back on in a week, so I'll have a good few more miles of 'testing' (mega Welsh B-road fun) complete.
Fingers crossed.
