Hi guys, I've had a search and and cant find anything that matches the noise my Aurion makes when it starts up! This is intermittent but more harsh when its cold or when the engine has rested but still warm. I get around 1-2 seconds of rattling on start up that is as loud rubbing a metal bar along a corrugated fence. It is so loud people in the car park look over! just a bit worried as they could not demonstrate the problem at the service done last week (typical hey)
