Maintenance
|
Service Intervals
|
Oil Change:
|
Typically 7,500 - 10,000 miles (12,000 - 16,000 km) or 12 months, depending on driving conditions and oil used (synthetic oil recommended).
|
Timing Belt:
|
Crucial for 1.8T and naturally aspirated 4-cylinder engines: 60,000 - 100,000 miles (96,000 - 160,000 km) or 5-7 years. Failure can cause severe engine damage. V6 engines use a timing chain.
|
Transmission Fluid Change:
|
Manual: Inspect for leaks; typically no fixed interval but check for clarity. Automatic: 30,000 - 60,000 miles (48,000 - 96,000 km), especially under severe use.
|
Coolant Change:
|
Every 2-3 years or 40,000-60,000 miles (64,000-96,000 km)
|
Fluid Specifications
|
Engine Oil Viscosity:
|
SAE 5W-40 or 5W-30 (VW 502 00 / 505 00 approved) for most gasoline engines. Check specific engine requirements.
|
Coolant Type:
|
G 12 / G 12+ (pink/red) or G 11 (blue/green), always check current fill and manufacturer recommendations for compatibility. VW TL 774-C, D, F.
|
Brake Fluid Type:
|
DOT 4 (VW TL 52161)
|
