Noise When Starting Car

[jackr1]

Hello,
When i start my car from cold when it starts it makes a noise for a while, sounds like a belt noise, However after ive driven around it no longer makes the sound.
Any idea what this is and how to fix it?
My car is a A3 2011 2.0tdi 170.

Thanks in advance,
Jack!

Mine makes a noise occasionally, for literally two seconds as the engine turns over, doesn't sound like a belt noise but more a slight vibration, like a slightly loose engine cover I think. It only makes this noise once every 20 or so startups.

I have checked the engine cover and the front rubber grommet has slightly corroded and the cover is slightly loose at the front BUT I'm convinced it's not that for some reason.

Once I've driven up the road and re started the engine it's completely gone.

Weird.
