Engine noise when starting. Help!!
i have an A4 2002 with 2.0L petrol engine (ALT) , when i start the car in the morning i hear a chain noise for like one second and it goes away, i have replaced the cylinder head chain with the adjuster but the noise is still coming. Any idea??

My Jetta and Audi do this, NO IDEA what it is but the jetta has been doing it for about 70k miles now and the audi has been doing it since I bought it, I don't think it is doing anything bad, I know its irratating but I don't think there is anything wrong with the cars.

Every cardoes this, as there is no oil on top of the motor after sitting for awhile. It does it even for a few seconds more right after an oil change because you've just drained all oil out and it needs to circulate through the filter also. No big deal! This is what it soumds like your talking about anyway.

i have been told that you need to check on the bucket tappets, you may need to replace them. i know at some point the car doesthis even at cold weather or till the oil reaches up when i start the car.

Cpagelll is correct. Also, the cam chain tensioner in the head (which drives the intake cam off the exhaust cam) tensions with oil pressure, so until pressure builds up, the chain will rattle. It's common and normal in these cars.
