I've got a 2010 model with 28K which now has started running rough on initial cold start-up. It's almost like it's misfiring but tough to say. Quite a strong smell of petrol as well. After a couple of minutes, she comes good and no issues at all when running part-warm or hot and no engine warning lights on. It's just the initial start-up when cold that's the problem. Trying to drive the car within a couple of minutes of cold start-up before the 'roughness' has stopped is a bit of a spluttery affair.
I installed a Shark Stage 1 remap a year ago but back to running factory map at the moment because car was in getting final service at dealership under warranty period a couple of weeks ago. Only other mod is Blueflame cat-back exhaust which means I've blanked off the factory rubber exhaust valve pipe by screwing in a small bolt but that was done almost a year ago and the cold-start problem just started fairly recently. Dealership forgot to reset my service indicator so I'm getting the "Service Due" warning every day but can't believe that's connected. Like I said above, car runs spot on otherwise and MPG hasn't deteriorated, it's just this annoying spluttering on cold start-up that's a pain
Any suggestions where to start with this would be greatly welcome!
