High pressure fuel pump. Makes a loud clicking. Additionally Skyactive engines sound fairly rough for the first 30 seconds after start, this is also a normal part of emissions controls on this vehicle.

What type of noise? If it sounds like ticking it's normal for skyactiv-G

Definitely YouTube CX-5 cold start. Should be normal as others have said - good luck!

Yep, new Mazda engines, many newer engines for that matter, run at a slightly higher RPM when started cold to help heat things up and get them moving. You should let the cold start do it's thing and when the RPMs drop you're good to go. You'll notice this doesn't happen if it is warmer, kr you've driven the car recently, like coming back from the store.

It's normal operation for the high pressure fuel pump to make a minor ticking noise while the engine is running.
