Why does my Audi A2 engine sputter when accelerating?

I recently noticed that my Audi A2's engine starting sputtering and hesitating when I try to accelerate. It seems to happen more when the car is cold. What could be causing this and how can I fix it?

It's possible that your fuel injectors may be clogged or dirty. Try using a fuel system cleaner to see if it helps. If that doesn't work, it may be time to have a mechanic take a look.

It could also be an issue with your spark plugs or ignition system. Check for any spark plug fouling or wear and tear on your spark plug wires. If necessary, replace them and see if the issue improves.

Another possible culprit could be a dirty air filter. Check and replace if necessary, as a clogged air filter can restrict air flow to the engine and cause sputtering.
