After the trip to the dealer they've apparently done a software update to fix the problem. Having driven the car a bit over the past few days I've not noticed the hiccup so maybe fixed! Need to drive the car a bit more before making a final judgement.
Dealer also said they'll need it back in to do a regen (I didn't leave enough fuel in it for them to do one) which should also help with the same issue apparently.
