Whilst i had the dash out, i checked to see what bulbs i didn't have, but found one that i did have that doesn't seem to do anything, and isn't even mentioned in the manual, its a green icon with a wheel spinning of some sorts with what looks like dirt being kicked up

Anyone know what this icon means?
Also, does anyone else engine management light come on and stay on until the engine is running? as mine doesn't go out until you start the engine..
