Our take, from owner reports
Owners of the 2000-2005 A6 describe a car that is genuinely enjoyable to drive and own when it has been well maintained, but one that demands constant attention and money as it ages.
18 problems reported (2 very frequent, 8 recurrent, 8 isolated) · high confidence
Window cables, ABS modules, seat controls, mirror motors and wiper pump motors failing one after another.
Including cold-start rattle and the high cost of replacement with the engine out.
Insufficient owner data available to declare a consensus. Partial signal: the 1.9 TDI is called "legendary" and "bullet proof," and the 2.4 and 2.8 are also described as bullet proof, while the 3.2 V6 is called one of the better Audi petrol engines and "bullet proof as long as you stick to the service schedule." The 2.7T is divisive: liked by some for its low-end torque but repeatedly called expensive and prone to issues. The 4.2 V8 draws the strongest warnings for timing chain and fuel costs. Manual and quattro variants are preferred over automatics.
Owners compare it most often with the Mercedes E-Class, Lexus (LS430/LS460 and general Lexus models), Subaru, BMW 5 Series wagon and Toyota.

Owners of the 2000-2005 A6 describe a car that is genuinely enjoyable to drive and own when it has been well maintained, but one that demands constant attention and money as it ages. The most common refrain is that the mechanicals: particularly the 1.9 TDI, 2.4, 2.8, 3.0 and 3.2 engines: are solid, while the electrical systems, transmissions and ancillaries are the real weak points. Several owners report playing "whack-a-mole" with sensors, modules and motors, and multiple long-term owners eventually moved on not because the car died but because the electrical faults became too frequent to justify. Sentiment is warmer toward the C5 (roughly 2000-2004) for its mechanical durability and toward the later 3.2 cars for their drivetrains, but almost universally owners warn that a neglected example will "eat you alive."
Owners consistently position the A6 as the more characterful but less sensible choice against Lexus, Toyota and Acura, which are repeatedly recommended when reliability and running costs are the priority. Against the Mercedes E-Class, owners split: some call the E-Class more comfortable and less likely to draw negative assumptions about the driver, while others prefer the A6's design and driving feel. Subaru is suggested as the way to get all-wheel drive without the repair bills. The A6 is framed as a car you buy because you want it, not because it is the financially responsible option: several owners explicitly say that if you cannot work on it yourself or afford surprise repairs, you should buy something else.
Owners advise choosing a manual or quattro over the automatic, with one stating plainly to avoid automatics in anything other than the V8 because the CVT gearboxes are fragile. The 1.9 TDI manual is singled out as the safest bet, and the 2.4 and 2.8 are named as durable. The 3.2 with the ZF6 gearbox is described as super reliable with a fluid change. The 2.7T is only recommended as a weekend or project car, not a daily driver, and only with a full service history. The 4.2 is not recommended for commuting due to fuel consumption and timing chain risk.
This generation suits buyers who can do their own maintenance or have a trusted specialist and a budget for surprises; it is repeatedly described as a poor choice for someone who takes the car to a shop for everything. Prefer a car with a documented long-term owner and extensive service records: one owner noted their car came with five times the purchase price in maintenance records and was the best of four they had owned. Inspect for timing chain rattle on cold start, transmission service history, electrical function of windows, seats, mirrors, ABS and climate controls, sunroof and skylight drains, rust in the wheel wells, and clogged drains in the valley between the windshield and engine. Test drive with cold oil, particularly on automatic cars. Owners warn that a cheap purchase price is meaningless if major work is pending, and that a car sitting for years is not necessarily a bargain.
A recurring theme is that the car's condition depends far more on how it was maintained over its 20-plus year life than on how the current owner treats it. Several owners note the A6 is quiet, relaxed and comfortable on long drives, and that the design still looks modern. One owner reported a 4,500 km European road trip in a 2.4 with no major trouble. Owners also note that adding auxiliary or Bluetooth audio is possible but often costly, and that the orange instrument displays are widely disliked.
