I think this issue has been mostly appearing on 2014 cars and with the fuel pump recall it doesn't surprise me however my car is from August 2014 and it is not covered by the recall (01/09/2013 – 30/04/2014). I have bought a car vertical though and it says my car was manufactured in 2014/01/01 but it did say "The date may be approximate".
Some people have said that getting the car tuned and removing the cold start fixes it others had their fuel pump replaced with the recall had also some new software that fixed it apparently as well.
I just don't fancy buying a fuel pump and then realising its a software issue. I will try logging the fuel pressures and see if they're within the norm when doing a cold start.
One thing I didn't mention is that it only happens after the car has been parked overnight.
