What is the most common issue with Audi car engines?

I am considering purchasing an Audi car but have heard about some engine troubles with this brand. Can anyone provide insight into the most common issue with Audi engines and how to address it?

The most common issue with Audi car engines is oil leaks, often caused by faulty seals. It's important to regularly check and top off your oil levels and have any leaks repaired by a reputable mechanic.

Another common issue with Audi engines is timing chain and tensioner failure, which can lead to costly repairs if not caught early. Be sure to have your timing chain and tensioner inspected and replaced as needed.
