What are some common engine issues in the Audi A2?

I've been experiencing some strange noises and decreased performance in my Audi A2. I'm wondering if there are any common engine issues that I should look out for.

One common issue with the Audi A2 is a faulty injection pump which can cause strange noises and loss of power. It's important to have this checked by a certified mechanic.

Another common issue is with the timing belt tensioner which can cause engine failure if not replaced in a timely manner. Make sure to have this part checked regularly.
