Why does my Audi A8 struggle with acceleration?

I noticed that my Audi A8 seems to struggle with acceleration, especially when I'm trying to merge onto the highway or pass someone. Is there anything that could be causing this issue?

One common cause of this issue could be a clogged air filter. I would recommend having your air filter checked and potentially replaced if it's dirty.

Another possibility could be a malfunctioning fuel injector. It's important to have this checked and repaired by a certified mechanic as soon as possible to avoid further issues.
