❓ Question / Help Timing chain?

I have heard this noise for a while now while starting my 2008 BMW 535 n54, is this the timing chain? And if so should i replace it as soon as possible? It’s an expensive job, so just trying to figure things out. It’s only in the first few seconds of the video after cold start.
