This would not normally be a problem in the short term, but left for any extended length of time,well it's really anyones guess! The problem may only be a minor one, or it could be more serious. You really need to have the fault codes read. You don't need to take it to the main dealer for this, in fact you could probably do it yourself with a fault code reader. Not sure about the availability of these in australia, but have a look on E Bay if you can't get one locally.
