[A8] Air conditioning service for 99 A8

[C1UE at prodigy.net]

Hi guys,

I was wondering what would be recommended in terms of 
preventative maintenance for the air conditioning 
system of my A8?

There is nothing wrong, but I've already plowed money 
into doing all of the engine related things (seals, 
tranmission fluid, 30K tune up/gas filter, 75K 
timing/serpentine) and now am looking at the 
peripheral systems...

Regards,

Calvin
