How can I fix the inconsistent engine revving in my 2019 Audi A3?

I've noticed that the engine revs up and down frequently, especially when accelerating or decelerating. It's becoming quite bothersome and I'm not sure what the cause could be. Any suggestions?

It's possible that your Audi A3 has a faulty Mass Air Flow sensor, which can cause inconsistent engine revving. You may want to take it to a certified mechanic to diagnose and replace if necessary.

Check your spark plugs and ignition coils. Worn out or faulty spark plugs can cause engine misfires which can lead to inconsistent engine revving. It's a relatively easy and affordable fix, so it's worth checking.

Another common culprit for inconsistent engine revving is a clogged air filter. Make sure to regularly replace your air filter to avoid any potential issues with engine performance.
