Ok, I have a service light on my dash and can't for the life of me figure out which service it is. Had one at 19500miles for oil. The car is on 21000 and it's light is back on. I'm nipping over to JC's tomorrow to get the fob checked but the icon that's showing isn;t in the manual. It's a circle with some liquid in it. Checked the water/coolant and that's fine, oil checks out ok. Anyone know what it means before I go in?

Cheers. .
