Maintenance
|
Service Intervals
|
Oil Change Interval:
|
Typically 7,500 to 10,000 miles (12,000 to 15,000 km) or 12 months, whichever comes first. Consult manual for exact Audi recommendations.
|
Timing Belt Interval:
|
Crucial interval, typically 40,000 to 60,000 miles (60,000 to 90,000 km). Failure can cause catastrophic engine damage. Manual will specify exact interval and procedure.
|
Fluid Specifications
|
Engine Oil Type:
|
Fully Synthetic 5W-40 or 10W-40 (API SG/SH or ACEA A2/A3). Manual will list precise specification.
|
Coolant Type:
