If you’re a typical user, you don’t need to overthink this: the 2013 Audi A6 Quattro Premium Plus is a capable luxury sedan with strong performance and refined interior quality, but it demands attention to maintenance. How to choose a reliable used A6? Focus on service records, known issue repairs (like PCV valves and water pumps), and verify timing chain tensioner history—especially on the 2.0T model. If you're not prepared for higher-than-average repair costs, this car may frustrate you despite its strengths.
Lately, interest in well-maintained C7-generation Audis has grown as more enter affordable price ranges. Over the past year, forums and market listings show increased buyer activity around high-mileage examples now priced under $10k. That shift makes due diligence even more critical—because lower prices often come with deferred maintenance risks.
About the 2013 Audi A6 Quattro
The 2013 Audi A6 Quattro represents the debut of the C7 platform, marking a significant leap in design, technology, and driving dynamics. Available in front-wheel drive (FWD) or Quattro all-wheel drive, the Premium Plus trim sits above base models with added features like xenon headlights, upgraded upholstery, and enhanced infotainment. Most U.S. models came with either a turbocharged 2.0L four-cylinder (211 hp) or a supercharged 3.0L V6 (310 hp), both mated to an 8-speed automatic transmission from ZF.
This generation introduced aluminum-intensive construction for weight reduction and improved fuel efficiency without sacrificing rigidity. The MMI system offered navigation, Bluetooth, and available touchpad input—a competitive package for its time. While praised for comfort and composure on long drives, the A6 never hid its mechanical complexity beneath the premium finish.
Why the 2013 A6 Is Gaining Popularity
Recently, the 2013 A6 has re-entered buyer consideration due to depreciation trends. Once a $60k+ executive sedan, many now sell between $6,000 and $11,000 depending on condition and mileage. That price drop brings German engineering within reach of drivers who previously considered only mainstream brands.
Enthusiasts appreciate the build quality, quiet cabin, and confident handling. Some owners report exceeding 200,000 miles with disciplined upkeep 1. This longevity potential—combined with strong safety ratings from initial release 2—makes it appealing for those prioritizing real-world durability over brand reputation.
The change isn't about improved reliability—it’s about recalibrated expectations. Buyers today understand these aren’t low-cost vehicles to own, but they value what they get in return: refinement, capability, and presence.
Types and Variants
The 2013 A6 came in several configurations, each with trade-offs.
2.0T FSI / TFSI (211 hp)
- Pros: Better fuel economy (~25 mpg combined), lighter weight, lower purchase price
- Cons: Higher likelihood of timing chain tensioner wear, PCV system failures, and turbocharger issues after 80k miles
If you’re a typical user, you don’t need to overthink this: the 2.0T offers decent performance but requires earlier attention to known weak points than the V6.
3.0T Supercharged (310 hp)
- Pros: Smooth power delivery, robust engine design, fewer major mechanical flaws reported at high mileage
- Cons: Slightly lower fuel economy (~21 mpg combined), higher insurance and repair costs
This engine has earned respect among long-term owners for resilience when maintained properly. One Reddit user with 106k miles expressed confidence in reaching 250k 1.
Transmission: ZF 8-Speed Automatic
- Pros: Smooth shifts, excellent calibration, durable when serviced
- Cons: Requires fluid changes every 60k–80k miles; neglect leads to shuddering or failure
If you’re a typical user, you don’t need to overthink this: transmission problems are rare if service records show regular fluid maintenance.
Key Features and Specifications to Evaluate
When assessing a used 2013 A6, prioritize verifiable mechanical health over cosmetic appeal.
- Engine Type: Confirm whether it’s a 2.0T or 3.0T—and research specific concerns accordingly
- Mileage: High mileage (120k+) isn’t disqualifying if supported by full service history
- Service Records: Look for timing belt/chain work, water pump replacement, transmission fluid changes
- MMI System: Test touchscreen responsiveness, GPS accuracy, and Bluetooth pairing stability
- Suspension: Listen for clunks over bumps—air suspension (if equipped) adds cost and complexity
- Tires & Brakes: Uneven wear may indicate alignment or brake caliper issues
When it’s worth caring about: High-mileage cars without documented maintenance, especially on 2.0T engines where timing chain risk increases post-80k.
When you don’t need to overthink it: Minor scratches or worn leather—these are predictable wear items easily addressed post-purchase.

How to Choose a Reliable Used 2013 A6 Quattro
Follow this checklist to reduce risk and make a confident decision.
Step-by-Step Checklist
- Obtain a CARFAX or AutoCheck report to confirm accident history and title status
- Verify full service records—look specifically for:
- Timing chain or belt service (2.0T needs early inspection)
- Water pump replacement
- Transmission fluid change (every 60k–80k miles)
- AC refrigerant recharges (common leak point)
- Inspect for coolant leaks—common near water pump and thermostat housing
- Test all electronics: windows, sunroof, seat memory, climate control, MMI functions
- Schedule a pre-purchase inspection (PPI) with an independent European specialist
Decision Flow
If you want a luxury sedan with sharp looks and composed driving manners:
→ Prioritize the 3.0T V6 over the 2.0T for better long-term peace of mind
→ Ensure the seller provides complete maintenance documentation
→ Budget $1,500–$3,000 for immediate service needs (fluids, brakes, sensors)
→ Avoid cars with air suspension unless budget allows for eventual replacement
Recommendations by Scenario
- First-time luxury buyer: Consider certified pre-owned (CPO) if available; otherwise, insist on PPI
- High-mileage commuter: Accept 100k+ miles only with full records and recent major services
- Winter driver: Quattro remains a top-tier AWD system—ideal for snow-prone areas
- Budget-conscious: Factor in $1,200–$2,000 annual maintenance average based on RepairPal data 3
Red Flags / What to Avoid
- No service history—or gaps exceeding 15k miles
