After a restart it would go away.
Today it's at BMW for a service, and I've asked them to check what's wrong.
They've called to say no codes stored except an exhaust flap issue. They've confirmed this would cause the issues I've mentioned.
Is there ANY possibility they are correct? I can't imagine how this is remotely connected given the way it drives.

They are way off the mark. The error code would be due to the exhaust flap plug being disconnected. Pull the piece of carpet away from the passenger rear light and plug it back in. The error will go away and the problem will still be there.
I had the same issue of rough running under load and it was caused by the o2 sensors. Mine would throw an error light every few days.
