Why does my Audi A2 1.6 FSI have a misfire issue?

I recently purchased a used Audi A2 1.6 FSI and have been experiencing a misfire in the engine. I changed the spark plugs and coil packs but the issue persists. What could be causing this problem and how can I fix it?

It is possible that the issue lies with the fuel injectors. They may be clogged or malfunctioning, causing inconsistent fuel delivery to the engine. I recommend taking your car to a mechanic for a proper diagnosis and replacement if necessary.

Check the ignition system, particularly the ignition control module. A faulty module can cause a misfire in one or more cylinders. Replace it if needed to resolve the issue.
