Are there any common issues with the Audi A2's engine?

I've been hearing mixed reviews about the durability of the Audi A2's engine. What are some potential problems I should watch out for?

According to several A2 owners, the most common issue is with the engine's timing chain tensioner. It tends to wear out and can cause sudden engine failure.

Another known problem is the air intake valve getting clogged, which can lead to poor performance and even Check Engine lights.

Make sure to regularly check the oil level and quality, as some A2 models have been reported to consume oil at a higher rate than normal.
