My car seems to have the same problem. I've had it about 2 months but in the last 1-2 weeks 5-6 times it hasn't started first time (my last car a 10 year old Escort always started first time) Also have the thing where say you were doing 50-60 and come up to lights, drop thew clutch just below 10 mph on the clock it drops the revs down to about 600 then it pops up to about 1,500-1,900 and dips again. So I'll be booking it in for this update which'll hopefully fix that.
I see some of you think the car is more rippy after that? I hope so because the car seems a tad slow for a small car w/ a 2 litre 150 bhp engine! My old 1.6 Escort seemed faster and more fun! If it doesn't change much soon I think'll have to trade it in for a something else which is a shame 'cos it looks nice.
