Routine Service Intervals

According to Audi’s service schedule for the B9 models, many routine tasks should be completed every 10,000 miles (approximately 16,000 kilometres) or 12 months, whichever comes first. This interval covers basic tasks such as:

• Engine Oil and Filter Change: Regular oil changes protect the engine and maintain performance.
• General Inspections: A thorough check of fluids, belts, and other vital components is carried out during each service.

Additional Scheduled Maintenance

While the 10,000-mile/12-month interval covers many routine tasks, there are other maintenance items that should be considered:

• Brake Fluid Replacement: It is recommended to change the brake fluid every two years, regardless of mileage. This helps maintain effective braking performance.
• Spark Plug Check: Spark plugs should be inspected regularly. Replacement is generally advised around 40,000 to 60,000 miles (approximately 64,000 to 96,000 kilometres), although exact timing may vary based on driving conditions and usage.
• Cabin and Air Filters: These filters should be checked during regular services. Replacement intervals can vary, so consult your owner’s manual for specific guidance.
• Tyre Rotation and Alignment: To ensure even wear, tyres should be rotated and the alignment checked at similar intervals to the routine service.

Model-Specific Considerations

The S4 and S5 B9 models share many maintenance needs, though slight differences in usage may arise. For instance, the S5—often chosen for its sporty design—might be driven more aggressively. This can mean that while the service schedule remains the same, components such as brakes and tyres may experience higher wear. It is advisable to monitor these parts more closely if the vehicle is used in a performance-oriented manner.

Transmission and other fluid services are generally performed as required by the vehicle’s condition and driving style. While many modern Audis feature components designed for longer intervals, always refer to the official service documentation for any additional requirements.

Keeping to Schedule

Adhering to the service intervals is important, not only for preserving performance but also for maintaining resale value. Always retain service records and ensure that any work is performed by a qualified technician familiar with Audi standards. Variations in driving conditions and usage mean that some vehicles may need attention sooner than the standard interval.

Final Thoughts

The maintenance schedule for the Audi S4/S5 B9 is straightforward: routine servicing every 10,000 miles (16,000 kilometres) or 12 months forms the core of upkeep, with additional checks such as brake fluid replacement and spark plug inspection complementing the schedule. Always refer to your owner’s manual or official Audi service documentation for details specific to your vehicle and driving conditions. With regular maintenance, these performance models can continue to deliver both reliability and the driving experience expected from an Audi.
