Why is my Audi A8's engine chugging?

I recently noticed that my Audi A8's engine has been chugging at low speeds. What could be causing this issue and what steps can I take to fix it?

This could be due to a clogged fuel filter or air intake filter. Try cleaning or replacing these components to see if it improves the engine's performance.

Another possible cause could be a faulty spark plug or ignition coil. Have these components checked and replaced if necessary.

It's also possible that your Audi A8's fuel injector is not working properly. Get it inspected and possibly cleaned or replaced by a mechanic.
