What are common issues with the Audi A1's engine reliability?

I've been considering purchasing a used Audi A1 but I've heard mixed things about their engine reliability. Can anyone share some insight into common issues with the A1's engine and how to address them?

Some possible issues with the Audi A1's engine could include faulty sensor readings, worn out timing belts, and leaky fuel injectors. To prevent these issues, make sure to regularly schedule maintenance and check for any warning signs. Remember that preventative maintenance is always less costly than dealing with a major issue.
