What would you recommend doing to keep my diesel Audi A6 Allroad well maintained?

I own a 2011 Audi A6 Allroad 3.0 TDI 240PS 6 speed auto with paddle shifts (98,000 miles). Other than 10,000 mile oil changes, what would you recommend doing to keep this on the road for a few years? It has had full Audi service from new. Is this the troubled gearbox I've read bad reports on? I sold my 2009 Audi A4 2.0 TDI 8 speed at 210,000 miles and am looking for similar again. I cover around 35,000 miles a year.
This will have a proper, reliable torque converter transmission, but the quattro Haldax clutch does require maintenance with regular fluid and filter changes. You might run into trouble due to a build up of ash in the diesel particulate filters, but other readers have successfully had them cleaned out by the Ceramex process at £350 a time. Vital to maintain the tyres so they are all the same type and have similar tread wear. Any significant disparity can confuse the electronics controlling the quattro system.
