What are some common maintenance issues with the Audi A7?

I have been thinking about purchasing an Audi A7, but I want to know what are some common maintenance issues I should be aware of before making the purchase?

One common issue with the Audi A7 is with the oil cooler. Make sure to regularly check the oil cooler for any leaks or cracks, as this could lead to engine damage if not addressed.

Another issue to keep an eye out for is with the air suspension system. It is prone to leaks and can be an expensive repair, so be sure to have it regularly inspected and serviced.

Be aware of any electrical issues with the A7, such as malfunctioning sensors or issues with the infotainment system. It's always best to have any issues diagnosed and repaired by a certified mechanic.
