2009 Audi A4

Service Overview

Regular maintenance helps preserve the performance, safety, and reliability of a 2009 Audi A4. Service needs should be determined by the vehicle’s mileage, engine and transmission configuration, maintenance history, operating conditions, and current symptoms.

Recommended Inspection Areas

• Engine oil level, oil condition, and oil filter
• Cooling-system fluid level, hoses, water pump, and evidence of leaks
• Brake pads, rotors, brake fluid, and hydraulic components
• Tire pressure, tread depth, alignment, and uneven wear
• Battery condition and charging-system performance
• Belts, seals, suspension components, and steering components
• Engine and transmission fault codes
• Exterior lights, wipers, and windshield-washer system

Before Authorizing Repairs

Ask for a diagnosis that identifies the underlying problem rather than relying only on a warning light or symptom. A written estimate should distinguish required repairs from preventive maintenance and note any items that can be monitored safely.

Because equipment and maintenance requirements vary among 2009 Audi A4 configurations, consult the owner’s manual and the vehicle’s service records for the applicable fluid specifications and service intervals.
