looks like a while ago now you were asking, but thought i would post just incase....
I had the EXACT same problem (on the exact same car, 55 plate sxi 1.2).... sweeping lefts seem to activate the warning light, and until I have made complaints the garage ignored the fact it was when i made left turns, and this is now the third time the cars in the garage in 2 weeks.
heres what they did so far:
1st time - new coil pack + sparks due to the misfire message on the computer,
2nd time - done tests and found contaminated fuel (still showing misfires on the computer) - flushed the engine/tank and new filter/fuel as your garage did the first time,
as neither of these seemed to work and i still got the issue on a sweeping left, a complaint was made and they now took the car in for a third time and have told me that they found a crack in the canister letting water in, and its going to take a few days to fix.... so hopefully this is the end of it, if it turns out to be anything else, i'll come back and update this again!
