The rattling noise at idle in your Audi A1's engine could be due to a worn timing belt tensioner. It is important to get this fixed as soon as possible to prevent further damage to your engine.

Another possible cause for the rattling noise at idle in your Audi A1's engine could be a loose exhaust heat shield. This is a relatively easy fix and can be done by tightening the bolts or replacing the heat shield if necessary.

Your Audi A1 may have low engine oil levels, causing the rattling noise at idle. Make sure to check your oil levels and top up if necessary. If the noise persists, it could indicate a bigger issue and you should take your car to a mechanic.
