Review of the 2004 Audi A6

  • Solid performance and an elegant cabin design make the A6 a worthy competitor in the luxury sedan class, but BMW's 5 Series is more athletic and Mercedes carries more brand cachet, so it can't be called a class leader just yet.

  • Safety
  • Pros

    Heavenly cabin furnishings, varied menu of engines, all-wheel-drive utility.

  • Cons

    Nonlinear steering, limited availability of manual transmission.

  • What's New for 2004

Purchased used with 62k miles

Vehicle: 2004 Audi A6 3.0 Avant quattro AWD 4dr Wagon (3.0L 6cyl 5A)

Bought this off the lot with 62k miles on it. This will be my daily driver. Purchased for it's all weather capability and european refinement. For a 10 year old car this one is in fairly good shape. Some gremlins do plague the car, phantom sunroof, power steering pump went in the first 20 days and driver side rear window does not work. But this is part and parcel for a 10 year old car. It is also a heavy drinker. 18 around town and 22-24 highway on premium gas. Beyond these nuances the car is capable, comfortable, solid on the road and for the money drives better than most newer cars and has more cargo space than most SUVs.

Great car

by on
Vehicle: 2004 Audi A6 3.0 Fwd 4dr Sedan (3.0L 6cyl CVT)

This is my 2nd Audi and with one exception, it's been my favorite. Did have to replace transmission "computer" chip outside of warranty and they don't come cheap. On the other hand the car has provided wonderful service, It's stylish, comfortable, quiet, reliable and gets exceptional milage - 22 to 24 in town and 30 to 32 on the road at 70 mph. I am, however, a geezer driver - as my children tell me - so I don't flog either the engine or brakes.

Phenomenal car

Vehicle: 2004 Audi A6 2.7T S-Line quattro AWD 4dr Sedan (2.7L 6cyl Turbo 5A)

Bought the '04 S-line in Sept '09 with 55k miles on it. Mint condition for 15k. Could not be happier! added APR chip to get HP to 310 and it really makes a difference. Used to have 3 series BMW and this blows it away. Build quality is so much better. best vehicle i've ever driven in foul weather (snow, rain). Very safe feeling in all situations. One thing i learned is Dealers will kill you on repairs. got to find an indy tech. watch out for the cam adjuster seal leak' DLR scam. they claim its $1200 in labor. only takes them 2 hrs! find an independent mechanic or get warranty. wonderful car. had not problems at 72k miles yet.
