Why is the engine of the Audi A1 making a rattling noise?

Every time I start my Audi A1, there's a noticeable rattling noise coming from the engine. I've checked the oil levels and everything seems to be fine. What could be causing this issue?

The rattling noise you hear could be due to a loose heat shield on the exhaust system. It's a known issue in some Audi models, including the A1. I would recommend taking your car to a mechanic to have this checked and fixed.

It's possible that there's a problem with the timing chain tensioner. I would suggest getting this checked as soon as possible to avoid any potential damage to your engine. It's a common issue in Audi A1 cars that have over 80,000 miles on them.
