i want to find the location of the aircon refill pipes on audi a8?

Answer 1

Have an A6 myself, and there is one fitting on the right side of the condenser, and one on the back of the compressor. Unfortunately, neither of them are a standard size, and both are on the hi-pressure side of the system. Just another reason Audi's are a real swine to work on. There are a few shops that will have an adapter for this fitting, but have to make some calls, and be very specific.

Answer 2

this is not user serviceable.
