Need my A6's AC sorted urgently – any Audi shops with quick turnaround?

Had the same on my A6 last July, barely cool and then warm. It was the condenser, packed with sand and pitted from stone hits, not the compressor. Called a shop at 8am, offered to wait, and it was done by mid-afternoon, so don't give up on same-day.
