Engine Options:
Common engines for 2010 Audi A3 included the 2.0 TFSI (turbocharged gasoline direct injection) and the 2.0 TDI (turbocharged diesel direct injection). The 3.2L V6 may also be available in certain markets.
2.0 Tfsi Horsepower:
Typically around 200 hp (147 kW).
2.0 Tfsi Torque:
Typically around 207 lb-ft (280 Nm).
2.0 Tdi Horsepower:
Typically around 140 hp (103 kW).
2.0 Tdi Torque:
Typically around 236 lb-ft (320 Nm).
Fuel Delivery:
Direct injection (FSI) for gasoline engines, Common Rail direct injection for TDI engines.
Fuel Type:
Premium Unleaded Gasoline (91 octane or higher recommended for TFSI), Diesel Fuel for TDI.
Emission Systems:
Catalytic converter, oxygen sensors, EGR (Exhaust Gas Recirculation) for TDI, particulate filter for TDI (DPF).
Oil Change Interval:
Typically every 10,000 miles (16,000 km) or 1 year, whichever comes first. Flexible service intervals (e.g., up to 18,000 miles or 2 years) may be indicated by the car's onboard computer based on driving style.
Timing Belt Interval:
For models with the 2.0 TFSI engine, timing belt replacement is typically recommended around 100,000 - 120,000 miles (160,000 - 190,000 km). Check specific engine code for exact interval. TDI models use a timing chain.
Brake Fluid Interval:
Recommended every 2 years, regardless of mileage.
Engine Oil Specification:
Audi Approval 502 00 or 504 00, viscosity SAE 0W-30, 5W-30, or 5W-40 (check owner's manual for specific engine requirement).
Coolant Specification:
G12 Plus (G 12+) or G13, a silicate-free, long-life coolant, typically pink or purple.
Power Steering Fluid:
Specific hydraulic fluid required for electro-hydraulic systems, consult manual for part number.
Common Issues:
PCV valve failure (leading to oil leaks and rough idle), ignition coil failures, potential for carbon buildup in direct-injection engines (TFSI), DSG mechatronic issues, oil consumption in some TFSI engines.
