What owners say about this generation

Overview

Audi A6 (2012-2018)

Overall Sentiment

Owners of the 2012-2018 A6 are generally positive, praising the 3.0T supercharged engine as one of Audi's most reliable and the ZF 8-speed transmission as stout and well-programmed. The car is described as comfortable, solid, and a great value for its depreciation. However, owners consistently warn that high-mileage examples (over 100k-140k miles) require a thorough pre-purchase inspection with a VAG-compatible scan tool, as generic OBD2 scanners miss stored codes. The 2.0T engine is viewed less favorably, with mentions of oil burning issues, and the 2.0 TDI is considered reliable but underpowered for the car's weight, with expensive AdBlue system concerns. The motorized MMI screen is a known annoyance, and Bluetooth music streaming is absent until 2014.

Positioning vs Competitors

Owners cross-shopping Japanese sedans note that the Audi A6 offers a more refined interior, better driving precision, and a more effortless feel from the supercharged V6, but they acknowledge that Japanese competitors will cost less to own and maintain over the long term. The A6 is seen as a more premium and engaging choice, but not as a budget-friendly high-mileage option.

Best Version According to Owners

The 3.0T supercharged engine (available throughout the generation) is widely considered the best and most reliable powertrain for this generation. Within the 3.0T, the CTUA engine variant is recommended over the earlier CGXB, as the CTUA has revised materials and fewer oil-burning and PCV system issues. The 8-speed ZF automatic transmission is strongly preferred over the 7-speed.

Recommended Configurations

Owners recommend the 2012-2018 A6 with the 3.0T engine and the 8-speed automatic transmission. For the 3.0T, the CTUA engine (found in later model years) is preferred. The 2.0T is not recommended due to oil burning issues, and the 2.0 TDI is only recommended if the buyer is prepared for potential AdBlue system failures. The Prestige trim is noted as desirable for its technology and sound system.

General Recommendations

This generation is best suited for buyers who can afford proper maintenance and repairs, especially on high-mileage examples. Owners strongly advise getting a pre-purchase inspection (PPI) from an independent Audi specialist and using a VCDS or OBDeleven scan tool to check for hidden codes, as a generic OBD2 scanner will not catch all errors. A seller who refuses a scan or PPI is a major red flag. For high-mileage cars (over 100k miles), budget for common repairs such as water pump, PCV valve, motor mounts, and control arms. Preventive maintenance, including frequent oil changes (every 5,000-6,000 miles) and transmission fluid changes every 50,000-100,000 miles, is key to longevity. The 2012 model year is the first of the C7 generation and may have some early-production quirks, but is still considered solid if well-maintained.

Reported Issues

Motorized MMI screen failure — Recurrent: The screen mechanism can break, and the screen may not retract or extend properly.

Water pump leaks — Very frequent: A common failure on the 3.0T, often addressed as preventive maintenance.

PCV valve failure — Recurrent: Known to fail on the 3.0T, especially on earlier CGXB engines.

Motor mount failure — Recurrent: Engine mounts can leak and fail, causing vibration at idle.

Control arm/suspension wear — Recurrent: Control arms and suspension components are common wear items at higher mileage.

No Bluetooth music streaming (pre-2014) — Recurrent: A notable annoyance; requires adapters or aftermarket solutions like Tune2Air.

AdBlue system failures (2.0 TDI) — Recurrent: Sensors, tank, and pump are a single unit; failure can be very expensive and parts may have long wait times.

DPF and EGR clogging (2.0 TDI) — Recurrent: Common on Euro5 and later diesels, especially with short trips.

Air suspension leaks (Allroad) — Recurrent: Rear struts can leak at the top seal around 200,000-220,000 km; compressor may fail if driven with a leaking strut.

Timing chain tensioners (3.0T) — Isolated: Mentioned as a maintenance item, but not a widespread failure.

Intake manifold failure — Isolated: Mentioned as a potential issue on high-mileage 3.0T engines.

Secondary air injection failure — Isolated: Mentioned as a possible issue.

Remarks

Owners emphasize that the 3.0T supercharged engine is a "known quantity" and that preventive maintenance is the key to high mileage (many report 200,000+ miles with proper care). The 2012-2018 generation is considered more reliable than the subsequent C8 generation, which has reported rocker arm and piston skirt issues. A VCDS or OBDeleven scan is considered essential before purchase, as it can reveal stored codes, timing chain stretch, and DSG/clutch health that a generic scanner cannot.
