What causes the engine to misfire on an Audi A4?

I've been noticing that my Audi A4 has been misfiring lately. What could be causing this issue and what steps should I take to address it?

One of the common causes of engine misfires in an Audi A4 is a faulty ignition coil. I would recommend checking and possibly replacing the ignition coils.

Another potential cause is dirty or clogged fuel injectors. Try using a fuel injector cleaner or have them professionally cleaned.

A low battery voltage can also lead to engine misfires. Make sure your battery is in good condition and has enough charge.
