Vehicle History Report

What Problems Does the 2006 Audi S4 Have?

The 2006 Audi S4, like other B7-generation Audi models, has some frequently reported problems and reliability concerns. The most significant is the timing chain issue. The timing chain tensioners and guides can wear prematurely, leading to chain slap and, in severe cases, engine damage. This is an expensive repair, often costing several thousand dollars.
Another common issue is related to the front suspension control arms. These components can wear out relatively quickly, resulting in clunking noises and poor handling.
Oil leaks are also a common problem, particularly around the valve cover gaskets and the rear main seal.
The cooling system can also be a source of trouble. The radiator, water pump, and thermostat can fail, leading to overheating. Regular maintenance and coolant flushes are crucial.
Electrical issues can also occur, including problems with the central locking system, power windows, and instrument cluster. Diagnostic scans are essential to pinpoint the source of these issues.
While there haven't been widespread recalls specific to the 2006 S4 for these issues, it's essential to check the NHTSA website for any applicable recalls related to safety or emissions. Overall, long-term reliability can be a concern if preventative maintenance is neglected.

How long will the 2006 Audi S4 last?

Given the age of the 2006 Audi S4, most examples will have accumulated significant mileage. With proper maintenance, owners can expect to reach 150,000 to 200,000 miles or more. However, long-term durability depends heavily on consistent and thorough maintenance. Weaknesses over time include the aforementioned timing chain issues, suspension wear, and potential for increased oil leaks. Neglecting these areas can significantly shorten the vehicle's lifespan and lead to costly repairs. Good maintenance records are crucial when considering a used 2006 S4.

What Technology & Safety Features are Included?

The 2006 Audi S4 came with a decent array of technology and safety features for its time. Standard features included a premium audio system (often with a CD player), dual-zone automatic climate control, and xenon headlights. Optional entertainment features included a Bose sound system upgrade and a navigation system with a small screen. Driver-assistance features were limited compared to modern cars but included available rear parking sensors.

Safety features included standard anti-lock brakes (ABS), electronic stability control (ESP), and front and side airbags. The Cabriolet version also featured a rollover protection system.

While not as advanced as current vehicles, the S4's tech was competitive for its era. The navigation system is outdated by today's standards, and smartphone integration is limited. There were no advanced driver-assistance systems like lane departure warning or adaptive cruise control.

Crash test ratings from the IIHS and NHTSA are available. The NHTSA gave the 2006 Audi A4 (the S4 is based on the A4) generally good ratings, with five stars for front and side impact protection for front occupants. The IIHS ratings vary, so it’s best to consult their website for specific results.

Overall, the 2006 Audi S4 prioritized performance and driving experience over cutting-edge technology. It offered a solid set of standard and optional features, but it's important to remember its age when evaluating its technological capabilities.

What Colors Options are Available?

2006 Audi S4 Prices and Market Value

When new, the 2006 Audi S4 had a starting price in the mid-$40,000s, potentially reaching into the mid-$50,000s with options. As of today's used market, prices typically range from around $5,000 to $15,000 or more, depending on condition, mileage, and location. The S4 has depreciated significantly due to its age and potential maintenance costs. Factors affecting resale value include the car's overall condition, service history (especially timing chain maintenance), transmission type (manual transmissions tend to command a premium), and geographical location. Low-mileage, well-maintained examples fetch higher prices.

2006 Audi S4 Cost of Ownership

The 2006 Audi S4 is generally considered a costly vehicle to own long-term. Insurance premiums will likely be moderate, but fuel costs can be high due to the V8 engine's fuel consumption.

How Does the 2006 Audi S4 Compare to Other Convertible?

The 2006 Audi S4 competed with cars like the BMW 335i (E90 generation), Mercedes-Benz C55 AMG (W203), and Infiniti G35. In terms of performance, the S4's V8 offered a unique sound and character compared to the BMW's inline-six. The C55 AMG delivered even more raw power but at the expense of handling finesse. The G35 offered a more affordable alternative with decent performance.

In terms of features, the S4 was competitive but didn't necessarily stand out. The BMW offered more advanced technology options, while the Mercedes focused on luxury appointments. Reliability is where the S4 falters somewhat, as the BMW and Infiniti models tend to be more reliable overall.

Price-wise, the S4 now occupies a similar price point to its rivals on the used market. If reliability is a major concern, the Infiniti G35 or a well-maintained BMW 335i might be better alternatives. The Mercedes C55 AMG is a compelling option for those prioritizing raw power over all else.

Ultimately, the S4 appeals to those who appreciate its unique combination of V8 power, all-wheel drive, and understated styling. However, potential buyers should be prepared for potentially higher maintenance costs compared to some of its rivals.
