Crazyxa it ended up that it did have a flat battery, but for no apparent reason eg lights left on ect. The battery had been replaced 6 months earlier and has been charged and tested as ok as has the charging system but this vehicle has had a few electrical issues causing ECT faults causing loss of throttle whilst driving as well. Throttle body has been replaced but it still has random ECT fault on the dash, Mostly on cold start up . Car has come home back to me from melb with the ETC on the dash but has not played up since.
