What are some common engine issues in the Audi A6?

I've been noticing some strange noises coming from my engine in my Audi A6. What are some common issues that could be causing this?

One common issue that could cause strange noises in your Audi A6's engine is a faulty timing belt. It's important to get this checked and replaced if necessary to avoid any potential engine damage.

Another possible issue is a malfunctioning fuel pump. This can cause the engine to sputter or have trouble starting. It's best to get this checked by a mechanic as soon as possible.
