Q3 noisy top end when cold
 

Hi,
I'm new to this forum, and I've just purchased a 2015 Audi Q3, and so far very pleased with it.
However, I do have a question, when starting it and the engine is cold, it's noisy from the top end of the motor, sounds like the lifters, then it will go off after about 30 seconds and all is okay.
Is this normal?
Thanks
Brian
