I have a 2004 idea 1.4 and yesterday the little yellow triangle with the ! in the middle lit up. The car runs fine and all fluids seem to be at the correct levels. It's not due a service for about 4000 miles but i don't want to wreck the engine by waiting that long to get it seen to. If i have to take it in i will but i would rather fix it myself than pay fiat big labour charges for a 2 quid component that just plugs in.
