The 2003 Audi A6 is a mid-size luxury sedan and wagon, part of the C5 generation (1998-2004). Key trims included the 2.7T, offering a potent twin-turbo V6, and the 3.0, providing a smoother, naturally aspirated option. Pricing ranged from the mid $30,000s when new. The A6 was popular for its sophisticated design, comfortable ride, and available quattro all-wheel drive, giving it a premium feel and all-weather capability.
The Good
The 2003 Audi A6 offers a blend of performance with its available turbocharged V6, and a comfortable, quiet ride. Its stylish design and available quattro all-wheel drive provide emotional appeal. Practical buyers appreciate the spacious interior, solid build quality, and the potential for good value on the used market. While not the most efficient, it offered decent fuel economy for its class.
The Bad
The 2003 Audi A6 can be prone to certain issues. Watch for timing belt failures (especially on the 2.7T), electrical problems, and suspension wear. Oil leaks are common, and the multi-link front suspension can require costly repairs. The infotainment system is also dated. Thorough inspection before purchase is crucial.

What Problems Does the 2003 Audi A6 Have?
The 2003 Audi A6, like many European cars of its era, has some frequently reported problems. One of the most significant concerns is the timing belt, especially on the 2.7T engine. Failure to replace it on schedule can lead to catastrophic engine damage. Oil leaks, particularly from valve cover gaskets and the rear main seal, are also common.
Electrical gremlins can manifest in various ways, from malfunctioning sensors to issues with the central locking system. The multi-link front suspension is known for wearing out bushings and control arms, leading to expensive repairs. The automatic transmission can also experience problems, particularly with harsh shifting. The climate control system's display screens can fade or fail.
While specific recalls for the 2003 model year might be found through a VIN search on the NHTSA website, common A6 recalls often involved airbag issues or fuel system components. Long-term reliability can be a concern due to the complexity of the car's systems and the use of potentially less durable materials in certain components. Maintaining meticulous records and addressing issues promptly can help mitigate these concerns.

Maintaining meticulous records and addressing issues promptly can help mitigate these concerns.
How long will the 2003 Audi A6 last?
A well-maintained 2003 Audi A6 can realistically reach 200,000 miles or more. However, longevity heavily depends on consistent maintenance. Average mileage at this age is likely between 150,000 and 250,000 miles. Poor maintenance accelerates wear and tear, leading to premature failures of components like the transmission, suspension, and engine. Regular oil changes, timely timing belt replacements (if applicable), and addressing minor issues promptly are critical for maximizing its lifespan. Long-term weaknesses include the aforementioned suspension wear, electrical issues, and potential for corrosion in colder climates.
What Technology & Safety Features are Included?
The 2003 Audi A6 offered decent tech for its time, though it lags behind modern standards. Standard features included a premium sound system (often Bose), automatic climate control, and power accessories. Entertainment was primarily through a CD player and AM/FM radio. Optional features included a navigation system (which now appears quite dated), a sunroof, and heated seats.
Driver-assistance features were limited compared to today's vehicles, with antilock brakes (ABS) and traction control being the primary systems. Stability control (ESP) was available on some trims. Safety features included front and side airbags.
Crash-test ratings from the NHTSA and IIHS should be consulted for specific data. Generally, the A6 performed well in crash tests for its era, providing good occupant protection. Keep in mind that safety technology has advanced significantly since 2003, so a newer vehicle will inherently offer superior safety in a collision. Remember to verify safety ratings from reputable sources like IIHS and NHTSA.
The Audi Navigation system, while available as an option, now seems extremely dated by modern standards.

2003 Audi A6 Prices and Market Value
When new, the 2003 Audi A6 ranged from the mid $30,000s to the low $40,000s, depending on the trim and options. On the used market, prices typically range from $3,000 to $7,000, depending on condition, mileage, and location. Depreciation has been significant due to the car's age and higher maintenance costs associated with older European vehicles. Factors affecting resale value include: overall condition, documented maintenance history, low mileage, and desirable options like quattro and the 2.7T engine (although this can also be a liability due to potential maintenance). The S6 commands a higher price but has specialized maintenance.
2003 Audi A6 Cost of Ownership
The 2003 Audi A6 is generally considered costly to own due to potentially high maintenance and repair bills. Insurance costs may be moderate, depending on your driving record and location. Fuel economy is average for its class, but not exceptional. Maintenance, particularly for the 2.7T engine and quattro system, can be expensive. Parts may be more costly than those for domestic vehicles. Long-term ownership requires diligent maintenance and the willingness to address potential issues promptly to avoid escalating costs.

How Does the 2003 Audi A6 Compare to Other Sedan?
The 2003 Audi A6 competed with the BMW 5 Series, Mercedes-Benz E-Class, and Acura TL. In terms of performance, the A6 2.7T offered competitive acceleration, while the BMW 5 Series often had a sportier driving feel. The Mercedes-Benz E-Class generally prioritized comfort. Feature-wise, all three offered similar levels of luxury, although the A6's infotainment was becoming dated by 2003.
Reliability is where the A6 often lagged behind. The BMW and Mercedes-Benz could be expensive to maintain, but the A6's potential for timing belt issues and electrical gremlins made it a riskier proposition. The Acura TL, while not as luxurious, offered significantly better reliability and lower ownership costs. Price-wise, used A6 models are typically less expensive than comparable BMW or Mercedes-Benz models, reflecting their perceived reliability.
Alternatives to consider include the Acura TL for better reliability, the Lexus ES300 for a smoother, more comfortable ride with excellent reliability, or a newer, more reliable mid-size sedan, even if it's not a luxury brand. If you prioritize performance above all else, a well-maintained BMW 5 Series might be a worthwhile alternative, but be prepared for potential maintenance costs.

Final Verdict: Is the 2003 Audi A6 a Good Sedan?
The 2003 Audi A6 is ideal for someone who appreciates European styling and a comfortable ride and is willing to accept potentially higher maintenance costs. It's worth buying *used* if you find one in excellent condition with a documented maintenance history, preferably with the timing belt recently replaced (if applicable). The 3.0 V6 may be a safer bet than the 2.7T due to potential turbo and timing belt issues. Avoid examples with obvious neglect or warning signs. A pre-purchase inspection by a qualified mechanic is essential. Be prepared for ongoing maintenance costs and consider it a project car, not a primary source of reliable transportation, especially if you're on a tight budget.
