Years: built 2005 to 2015. Facelift in spring 2009.
Most common: timing chain wear on the 3.0 V6 TDI, air suspension faults, and shift faults in the 8-speed automatic.
Reliability: 3/5, because the timing chain and air suspension can be costly, and several faults are known.
DIY: 1/5, because chain, suspension and gearbox work needs a workshop with diagnostic software. The checks below need no tools unless marked "needs a scanner".
Prefer: a car without air suspension, and a 3.0 TDI with proof of timing chain work.
Avoid: a 3.0 TDI with a rattle on cold start, a car with air suspension that sags overnight, and any car with shift jerks.

3.6 FSI VR6 (BHK, 2006-2010): timing chain stretch is reported.
4.2 FSI V8 (BAR): no fault confirmed in the sources read.

3.0 TDI V6 (BUG, CJG, CJM, CRC): timing chain and fuel injector wear, see Known issues. Brake servo campaign 08/2014, see Recalls.
4.2 TDI V8 (BTR, CCF): no fault confirmed in the sources read.
6.0 V12 TDI (CCG): no fault confirmed in the sources read.
6-speed automatic (to 2010): no fault confirmed in the sources read.
8-speed automatic (from 2010): shift faults, see Known issues.
Quattro all-wheel drive with Torsen centre differential: no fault confirmed in the sources read.

Start the engine cold and listen for a rattle in the first seconds. A rattle means a stretched chain or a worn tensioner. Ask for proof of chain work.
If the car has air suspension, check that the body keeps its height after the car has stood overnight. A sagging car means a fault in the bellows or the compressor.
On a test drive, check for smooth shifts from 4th to 5th and back down. Jerks or kicks are a warning. Ask whether a software update was done.
On a cold start, listen for knocking, and look for smoke from the exhaust. Diesel in the engine oil is a serious warning. Ask for injector records.
Look for water traces in the footwell and the boot, and for cracked paint at the glue seams of the roof and windscreen. Ask whether the roof drains were cleaned.
Test the keyless entry from both front doors, with the key and with the handle. Dead antennas are a known fault.
Run the wipers on a test drive. Both arms should sweep fully and not stop or jerk. A seized wiper linkage is a known fault.
Check every recall campaign by VIN, including the 3.0 TDI brake servo (2014) and the 3.0 TFSI fuel rail (2015). Ask for the dealer's record of each repair.
