The latest news in Cyclo pads is the Edge system. Anthony did a thread about it a little while ago. Not having tried that yet, I get most of my Cyclo pads from TOL, where they also have Hi-Temp polishes, which work well via Cyclo. So do 1Z polishes and the old, discontinued 3M PI-III RC 05933 and MG 05937.
I wouldn't like to try for 100% perfection on an Audi using only the Cyclo, but if I *had* to do it that way I'd probably use a mix of Hi-Temp Extreme Cut with just a little 1Z Ultra/Extra mixed in. Then I'd follow up with something milder like straight 1z Paint Polish and top with a heavy carnauba.
Or you might try the H-T EC followed by Blackfire/Menzerna finishing polish for SRC, but I haven't tried that progression yet so no first-hand experience.
