The A6 is Audi's executive sedan, covered from the 1994 C4 through the C5, C6, C7 and C8 generations. Engines range from four-cylinder TFSI and V6 TDI units to the supercharged and turbo 3.0-liter V6.


The 2007 Audi A6 belongs to the A6 C6 generation, built for model years 2005–2011. Most procedures are shared with the other years of this generation, but engines, options and wiring changed from year to year, so the manual is made for the 2007 model year.
Check the model year on your VIN: on a 2007 vehicle the 10th character of the 17-digit VIN is “7”. Vehicles built for North America always carry the model year in that position; on some European or Australian vehicles it may be left unused, so in that case go by the registration papers or the build plate.
At about 19 years old, a 2007 vehicle is in the age range where wiring, rubber hoses, seals and corrosion repairs take most of the work, and where original factory information is hardest to find.
Same generation: 2005 Audi A6, 2006 Audi A6, 2008 Audi A6, 2009 Audi A6, 2010 Audi A6, 2011 Audi A6.
