Hi guys, I'm driving a A6 2009 2.0TFSI.
Since 2 years ago I have noticed that I get a rattle when starting the car, it is very briefly aprox 1 second.
One thing I have noticed is that it never rattles when the temperature is below 5-6 celcius.

Video clip.

Could this have something with the tensioner to the chain behind the engine? I've heard that the oil leaks down on them and the building up of oil pressure generates this sound. Keep in mind that in the video it sounds like its coming from under the car, but it's only the sound that bounces when the hood is closed.

Never had CEL' Oil pressure drop or anything, Oil pressure is checked manually and its good.

Some history about the car.
* Long Life service up to 60 000km with maximum of 19 000- 20 000km after that every 10 000 - 15 000km.
* I've used 5W-30 Long life oil since this summer, after my tune I went with 5W-40 Castrol
* Never had a problem with anything on the car
* Things I've changed just for procotion: PCV Valce, Dump valve, Cam follower.
* This summer I've changed belt and waterpump and everything that goes with it, all OEM.
