I am having the same sort of issues with my 2007 Aurion, I have had it to the mechanic where they did a engine flush and Service replacing oil filter and oil, pressure tested the cooling system. Did a diagnostic scan on Control Module and analyse of live data channels, cleaned the pcv valve. When i got it back it didnt blow smoke for about a week then all of a sudden it started again doesnt do it everytime i start up may not do it first thing but drive 15 ks park for an hour then it does it when i start up again. The mechanic doesnt seem to know is causing it as it never did it while they had it (typical). So frustrating not know what the cause is as other than that have never had a problem with the car in 6 years of owning it. IMG_1931.MOV

Not sure if it varies between states but in WA they need to wired up so that a) only come on with park lights on (instead of headlights) or b) when headlights are on on high beam

I would get it checked out one of my other cars (no longer own) if i filled it over half i would get a strong petrol smell it turned out that the fuel tank had split half way up hence when filling over half would get the smell once i had the tank replaced the problem was gone
