Why does my Audi A8 engine make a knocking noise on startup?

I've noticed that my Audi A8 makes a loud knocking noise when I start the engine, but it goes away after a few seconds. Is this normal or should I be worried about potential engine issues?

This could be caused by a few different factors, so it's best to bring your Audi A8 to a trusted mechanic for an inspection. They will be able to pinpoint the exact cause of the noise and advise you on any necessary repairs.

If the knocking noise only lasts a few seconds and then goes away, it's likely just normal engine noise as the car warms up. However, to be safe, it's always a good idea to have a professional take a look if you have any concerns.

I experienced the same issue with my Audi A8 and it turned out to be a problem with the timing chain tensioner. I would recommend getting it checked out and fixed as soon as possible to avoid any potential damage to the engine.
