I recently purchased a 2009 ATX Aurion (3.5L SemiAuto) from a Toyota dealer, the vehicle has covered 70k since new. I have recently noticed a ticking noise (barely audible but definitely there!)on startup from cold. After a couple of KM's when the engine has warmed up, the noise disappears. Apart from that, the engine is fine - no oil loss or leaks / rough driving etc. The only change I have made prior to the noise being noticed is that for the past couple of weeks, I have filled the car with E10, the handbook advises this is ok to use. The noise is not sufficient (at the moment)to take it to a garage/dealer to have a look at but these kind of noises tend to get worse not better! Any advice appreciated.
