Drivetrain Options:
Front-wheel drive (FWD), quattro permanent all-wheel drive
Transmission Fluid Type:
Specific specifications will be detailed within the manual (e.g., G 052 162 A2 for certain manual transmissions, G 052 990 A2 for Tiptronic)
Oil Change Interval:
Typically every 10,000-15,000 km (6,000-10,000 miles) or 12 months, whichever comes first, depending on driving conditions and oil quality. Specifics for synthetic oils will be in manual.
Timing Belt Replacement:
For 1.8L and V6 engines with timing belts (not chains), typically around 90,000-120,000 km (50,000-75,000 miles) or 5-7 years. TDI engines often use timing chains or belt with longer intervals.
