What is the reason behind timing chain issues in an Audi A5?

I've noticed that some models of Audi A5 are more prone to timing chain issues than others. Is there a specific reason for this?

The timing chain in an Audi A5 is driven by the crankshaft and therefore it is under a considerable amount of strain. This can lead to wear and tear over time.

One common reason for timing chain issues in the Audi A5 is the use of non-OEM engine oil, which can lead to premature wear and damage.

Another potential cause of timing chain problems in the Audi A5 is a faulty tensioner, which can cause the chain to become loose and skip teeth on the sprocket.
