Why does my Audi A7 keep losing acceleration during long drives?

I'm a proud owner of an Audi A7 but have been experiencing issues with keeping consistent acceleration on long drives. It's not a frequent problem, but it's happened enough times to be a concern. I haven't noticed any other issues with the car's performance and was wondering if anyone else has experienced this and knows the cause.

This could be a result of a dirty or clogged fuel filter. It's important to regularly replace your fuel filter to ensure proper engine performance. Try replacing it and see if the issue persists.
