Advice for buyers
What should I look for in a used Audi A8 saloon?
The A8 has had few reported problems so far. Nevertheless, it’s important to check your prospective purchase over thoroughly, as the A8’s a complicated car, and there are a lot of things that theoretically can go wrong.
Make sure that all of the touch-sensitive switches still work, for example, and that goes for the touchscreens too. You’ll also want to check all of the gadgets they control do what they’re supposed to – don’t rush this, as there’s so much to find your way around.

Is a used Audi A8 saloon reliable?
The A8 didn't feature in our most recent What Car? Reliability Survey. However, the A6, its smaller sibling, did, and it finished bottom of the luxury car class. Audi as a manufacturer came 18th out of 30 car makers in the same survey, which suggests the A8 will be average for reliability, if not one of the greats.
