Mines doing this now but doesn't clear and it came up an engine warning light, plugged it in to gs911 and says lambda sensor bank 2 fault. Apparently a common problem according to Phil crowe. Coil packs are also a common problem

Mine runs like a bag of spanners from cold, especially if the weather is warm. Coughs a couple of times then revs it's nuts off. I've complained about it at each service. They tell me the new software update sorts it but it's never worked. I just put it down to being euro 5 ( or 4 or whatever) . Runs sweet after 30 secs. Been doing it 3 years now
