What are the common maintenance issues in the Audi A6?

I am looking to buy an Audi A6, but I want to know what potential maintenance issues I should be aware of.

The most common maintenance issue with the Audi A6 is the timing chain failure. It is important to regularly check and replace the timing chain to avoid engine damage.

Another common issue is oil leaks, which can be caused by a faulty valve cover gasket. It is recommended to have this gasket checked and replaced every 60,000 miles.

Suspension issues, such as worn out shocks and struts, are also common in the Audi A6. Regularly check your suspension components and replace if necessary to ensure a smooth and safe driving experience.
