Noticeable rattling noise on low rev cold start. Gear Box Issue? Help Please... New bought Audi A4 2.0 TDI AUTO 2010

Hi Guys... I am a newbie to the forum. And thanks for looking at this post.

Recently I have bought an 2010 AUDI A4 2.0 TDI AUTO with 29000 miles on the clock from a franchised dealer. I have owned the car for 2 weeks now. I think I have got an issue now. The car will give a very noticeable rattling noise on low rev (Just above 1000 RPM but not idle e.g. around 30 miles cruising speed in D gear). This rattling noise only occurs when car is cold. The noise will go away after the car has been fully warmed up.

I am not sure about the issue.

Maybe a gearbox oil change is required?
Would you give me some advise please?
How should I approach to the dealership to explain this problem?

Many Thanks

Take it back to the dealer and explain the issue as you have here - it's their responsibility to find the fault and fix it. Sooner you mention it to them the better.
