Thanks for that advice. This is the first time I've logged in for a couple of weeks and during that time I took it to an auto electrician. He had it for half an hour, mentioned something about fixing a connection and, presto, no more faulty warning light. Looks like your suggestions below covered what was wrong.

It should close to help reduce engine vibration, if it does not then the FCV has failed or the wiring conection is bad. The part number for the FCV is 5142799AA and is available online in the states for about $260. Is there a reasonable place to get OEM parts in Australia without ordering through a dealer? The $1800 price quote you received would be considered highway robbery in our opinion.
It is highly doubtful that the ECM needs to be replaced, it it was bad there would also be a code P0606 and most times the vehicle just will not start. We hope this proves helpful.
