Why is my Audi A2 engine shaking while idling?

I have noticed that when I stop at a red light or in traffic, my Audi A2 engine starts shaking and I can feel it in the steering wheel. What could be causing this issue and how can I fix it?

This could be due to several reasons. One possibility is that there is a problem with the fuel injectors or spark plugs, which can cause misfires in the engine. Another possibility is that there is a vacuum leak in the engine, which can also cause shaking while idling.

I would recommend taking your car to a mechanic to have it checked out. They will be able to diagnose the issue and make any necessary repairs. In the meantime, you can try using a fuel system cleaner to see if that helps improve the smoothness of your engine.
