Why does the Audi A8 make a loud noise when I start the engine?

I recently purchased a brand new Audi A8 and noticed that when I start the engine, it makes a loud noise that lasts for a few seconds. Is this normal or should I be concerned?

Yes, it is normal for the Audi A8 to make a loud noise when starting the engine. This is due to the fuel injectors and ignition system operating at full capacity during startup. Nothing to be concerned about!

I had the same concern when I first got my Audi A8. After consulting with the dealer, I learned that the noise is actually the sound of the electric cooling fan kicking on, which is completely normal.

I've owned my Audi A8 for several years now and have never experienced any issues with the engine noise during startup. It's just the sound of a powerful engine coming to life!
