What are the most common maintenance issues in Audi cars?

I recently purchased a used Audi and I want to know what are the common problems and maintenance tasks that I should be aware of?

One of the most common maintenance issues seen in Audi cars is related to the engine oil consumption. It is recommended to check the oil level regularly and top it up as needed.

Another common issue is related to the electrical system, particularly with the battery and alternator. It is important to have the battery tested and replaced if necessary to avoid any unexpected breakdowns.

For Audi cars with a turbocharged engine, it is important to properly cool down the engine before shutting it off to prevent damage to the turbo.
