Got this car with 1.2 i-vtec a few weeks ago, did a deep check over the engine at the weekend - Valve clearance adjust, remove and clean injectors, clean throttle, new spark plugs, clean EGR valve, MAP and MAF sensors.
I now feel I know the engine pretty well but there are a few solenoids I can't figure out the purpose of. What are they?


And for those wondering like me, this one doses collected fuel vapours from the fuel tank in to the engine. You can hear it clicking during running sometimes.
