My A8's ready again, he's pissing on my shoes and socks. I had it fixed last year, I had it fixed in a garage... (waterbox drains clogged).
In the FAQ the topic is already discussed for the V8, I found here a link to the topic for the A8 (again with Paul Waterloo; the guy is really a real A8 god).

Can't really imagine why Audi drivers come to second place in this funny statistics about the frequency of GV per week, because rubber boots don't seem really erotic
