Our take, from owner reports
Owners of the 2012-2018 A6 (C7 generation) broadly regard it as one of the best used luxury sedan values available, with the supercharged 3.0T engine repeatedly described as bulletproof and the 8-speed ZF transmission as stout.
17 problems reported (1 very frequent, 8 recurrent, 8 isolated) · high confidence
The 3.0T supercharged V6 is the consensus best engine, with the 2017 model year frequently cited as the peak because it was the last year of the supercharged V6 and had major problems worked out. The 3.0 TDI is also praised as possibly the best engine in the A6 for reliability and overall character. The 2.0T has defenders who call it reliable and adequate, but a vocal contingent advises against it.
Owners compare it most often with the BMW 5 Series (G30 540i), BMW X5 M60, Mercedes-Benz C300, Lexus IS and Acura TLX.

Owners of the 2012-2018 A6 (C7 generation) broadly regard it as one of the best used luxury sedan values available, with the supercharged 3.0T engine repeatedly described as bulletproof and the 8-speed ZF transmission as stout. Praise centers on driving feel, power, snow capability, and comfort, while criticism focuses on running costs: water pump and thermostat failures, carbon buildup, oil consumption at high mileage, and expensive repairs when things do break. The 2.0T draws more mixed opinions, with some owners calling it perfectly fine and cheaper to maintain, while others explicitly steer buyers toward the 3.0T for reliability and power. The TDI diesel also has a loyal following for torque and economy, though owners note DPF and EGR clogging is inevitable on post-Euro5 diesels. Later model years (2016-2018) are generally viewed as having had major problems worked out, and the 2017 model is often singled out as the last and best year of the supercharged V6.
Owners position the C7 A6 as one of the best used-car value propositions among mid-sized luxury sedans, with one owner placing it ahead of the G30 540i while noting the BMW is more expensive as a newer generation. Against the C300 and 530i, owners in a three-way comparison leaned toward the A6 for reliability. Several owners say they would recommend Lexus or Acura to someone prioritizing reliability over driving feel, framing the A6 as the choice for those who accept higher maintenance in exchange for a better driving experience. The 3.0T is described as far more engaging than the 2.0T, with one owner calling the move from a 2.0T A4 to a 3.0T A6 a night-and-day difference.
Owners strongly favor the 3.0T supercharged V6 over the 2.0T for reliability, power, and tuneability, with one owner calling a stage 1 ECU/TCU tune mandatory and transformative. The 8-speed ZF automatic is preferred, and one owner advises avoiding the 7-speed if planning DIY service while noting the 8-speed can be rebuilt with minimal DIY skills. For the diesel, owners recommend tuning via Kerma TDI or Malone/Tunezilla for better power delivery and roughly 12% better economy. Prestige trim is described as the top regular trim with four-zone climate, ventilated front seats, and Bose audio, though owners note the trim premium largely disappears in the used market. A CarPlay/Android Auto retrofit is a common recommended addition.
This generation suits buyers who can budget for maintenance, with owners repeatedly citing $1-2k per year in repairs and recommending setting aside $3-5k for surprises. It is a strong choice for DIY-capable owners, as the C7 platform is described as relatively easy to work on for basic maintenance. Buyers should prioritize documented service history, get a pre-purchase inspection at an independent shop that knows European cars, and insist on a scan with VAG-Com or similar rather than a generic OBD2 reader. The 2017 model year is the most frequently recommended, and the 3.0T is preferred over the 2.0T. Owners advise avoiding cars with no maintenance records and caution that a cheap high-mileage example can become a money pit if deferred maintenance has piled up.
Owners frequently note that the 3.0T badge denotes a supercharged engine, not a turbocharged one, which confuses many buyers. The C7 is widely described as one of Audi's most reliable modern platforms, with multiple owners reporting 200k+ miles on original engines and transmissions. Maintenance costs are the dominant theme: owners warn that a $7-10k purchase price is only the entry point, and that independent Audi specialists save substantial money over dealerships. Several owners mention that dealer-documented service helps resale value. The diesel variants are noted as reliable but subject to eventual emissions equipment clogging.
