Vehicle History Report

What Problems Does the 2001 Audi S4 Have?

The 2001 Audi S4, like other B5-generation models, suffers from several frequently reported problems. The most notorious is oil sludge buildup in the engine, which can lead to turbocharger failure due to oil starvation. Regular oil changes with high-quality synthetic oil are crucial. The timing belt system is also a significant concern. If the timing belt fails, it can cause catastrophic engine damage. Replacing the timing belt, water pump, tensioners, and rollers is essential at specified intervals (typically 75,000 miles).
Electrical issues are also common, ranging from faulty sensors and modules to problems with the instrument cluster display. Suspension components, especially the front control arms, are prone to wear and tear, resulting in clunking noises and poor handling.
Specific recalls may vary depending on the region, but potential recalls could relate to fuel leaks, airbags, or other safety-related components. Owners should check with their local Audi dealer or the NHTSA website for any applicable recalls. Long-term reliability is a major concern, as these cars are now over 20 years old, and deferred maintenance can lead to a cascade of problems.

How long will the 2001 Audi S4 last?

Given their age, 2001 Audi S4 models can easily have over 200,000 miles, but mileage heavily depends on maintenance. Well-maintained examples can last well beyond, while neglected ones may struggle past 150,000 miles. Long-term durability is affected by the previously mentioned oil sludge issue, timing belt maintenance, and suspension wear. Proper preventative maintenance, especially frequent oil changes and timely timing belt replacements, are crucial for extending the car's lifespan. Weaknesses over time include increased likelihood of electrical problems and the need for more frequent replacement of wear items.

What Technology & Safety Features are Included?

The 2001 Audi S4's technology reflects its era. Standard features included a Bose premium sound system with a cassette player and CD player. A navigation system was available as a rare option, providing basic route guidance. Driver-assistance features were limited compared to modern cars, primarily consisting of anti-lock brakes (ABS) and traction control. Safety features included front airbags and side airbags.
Entertainment was primarily focused on the audio system, with limited connectivity options by today's standards. There were no built-in smartphone integration features like Apple CarPlay or Android Auto.
Driver assistance was basic, focusing on improving safety through ABS and traction control. More advanced features like adaptive cruise control, lane departure warning, and blind-spot monitoring were not available.
Crash-test ratings from the NHTSA and IIHS may be available, but could be limited due to the car's age. Generally, the B5 Audi A4 platform (upon which the S4 is based) performed reasonably well in crash tests for its time, offering adequate protection in frontal and side impacts. However, safety standards have evolved significantly since 2001.

What Colors Options are Available?

2001 Audi S4 Prices and Market Value

When new, the 2001 Audi S4 was priced in the $37,000-$40,000 range. Today, used market prices vary widely based on condition, mileage, and modifications. Expect to find them ranging from $5,000 to $15,000 or more for exceptionally clean or heavily modified examples.
Depreciation has been significant due to age and maintenance concerns. Resale value is strongly influenced by the car's mechanical condition, documented maintenance history, and the presence of desirable modifications (or lack thereof, for purists). Low-mileage, well-maintained examples in rare colors or with sought-after options command the highest prices.

2001 Audi S4 Cost of Ownership

The 2001 Audi S4 is not an economical car to own. Insurance costs can be moderate but depend on driving record and coverage. Fuel costs are relatively high due to the turbocharged engine and premium fuel requirement. Maintenance and repair costs are significant, with potential turbocharger, timing belt, and suspension issues. Long-term ownership requires a dedicated owner willing to invest in preventative maintenance and address potential problems promptly. Budget accordingly.

How Does the 2001 Audi S4 Compare to Other Sedan?

The 2001 Audi S4 competed with cars like the BMW 3 Series (E46), Mercedes-Benz C-Class (W203), and Acura TL. In terms of performance, the S4 offered similar power to the BMW 330i and Mercedes C320, but with the added advantage of Quattro all-wheel drive.
In terms of features, the S4 was competitive, offering a premium sound system and leather upholstery. Reliability is where the S4 falls short compared to its rivals, particularly the BMW and Acura. The S4 is known for more frequent and expensive repairs.
Price-wise, the S4 was similar to its German competitors when new. On the used market, it can be more affordable initially, but higher running costs may offset this.
Alternatives to consider include the BMW E46 330i/330xi (better reliability, similar performance) and the Acura TL (more reliable, front-wheel drive). The Subaru WRX (similar performance, but different driving experience) is also an option for those prioritizing performance over luxury. For a balance of performance and reliability, a well-maintained BMW might be a better choice, while the Acura offers superior reliability and lower running costs at the expense of AWD.

Final Verdict: Is the 2001 Audi S4 a Good Sedan?

The 2001 Audi S4 is ideal for enthusiasts who appreciate its performance, understated style, and the benefits of Quattro all-wheel drive, and who are prepared to handle its higher maintenance demands. It's worth buying if you find a well-maintained example with a documented service history, ideally one that has already had the timing belt and turbochargers addressed.
Given that it’s only available used, prioritize condition over mileage. Look for an S4 that has been meticulously cared for and avoid neglected examples. The Avant (wagon) offers added practicality, making it a good choice for those needing more cargo space.
