Why does my Audi A1's engine suddenly lose power?

I noticed that my A1's engine would suddenly lose power while driving at a constant speed. The engine warning light doesn't come on and there are no strange noises or vibrations. What could be causing this issue and how can I fix it?

It's possible that your engine is encountering misfires, which can be caused by a variety of factors such as a faulty spark plug or an issue with the fuel injection system. I suggest taking your A1 to a certified mechanic for a diagnostic test to pinpoint the exact cause of the issue.
