Why is my Audi A2 engine running rough?

I've noticed that my Audi A2's engine has been running rough lately. What could be causing this issue and how can I fix it?

The rough running engine could be due to a number of reasons like dirty fuel injectors, a faulty spark plug, or a clogged air filter. You should get your car checked by a professional mechanic to determine the exact cause and get it fixed.

It's possible that your Audi A2's engine is running rough because of a misfire. This could be caused by a faulty ignition coil or a faulty fuel injector. Make sure to get it diagnosed and repaired as soon as possible to avoid further damage to the engine.
