1 8T Engine:
1.8L (1781cc) DOHC 20-valve turbocharged inline-4. Power output typically around 150-170 hp and 165-195 lb-ft of torque depending on specific engine code and tuning.
2 8L V6 Engine:
2.8L (2771cc) DOHC 30-valve naturally aspirated V6. Power output typically around 172-190 hp and 199-210 lb-ft of torque.
2 7L V6 Engine:
2.7L (2671cc) DOHC 30-valve twin-turbocharged V6 (APB engine, often found in S4 models, but the manual covers it). Power output around 250 hp and 258 lb-ft of torque.
Boost Pressure 1 8T:
Typically operates with a turbocharger providing around 10-15 PSI of boost (specifics vary by code).
Fuel Delivery:
Multi-point fuel injection (MPI) for all engines, with sophisticated engine control units (ECUs) for precise fuel and ignition management.
Fuel Type:
Premium Unleaded Gasoline (91 octane or higher recommended).
NHTSA Front Crash Test:
Not directly available for all model years as per modern standards, but known for solid build quality and safety features.
ABS:
Anti-lock Braking System (ABS) was standard.
Traction Control:
Traction Control System (TCS) was often available or standard on Quattro models.
Airbags:
Front airbags for driver and passenger were standard. Side airbags were optional on many models.
โครงสร้างตัวถัง:
Reinforced safety cage construction, designed for occupant protection.
Oil Change Interval:
Typically every 5,000-7,500 miles or 6-12 months, depending on driving conditions and oil used. Consult the manual for specific recommendations.
Timing Belt Replacement:
For 1.8T and 2.8L V6 engines, the timing belt is a critical maintenance item, typically requiring replacement every 75,000-105,000 miles or 5-7 years. The 2.7T (APB) also requires this.
Engine Oil Specification:
Likely SAE 5W-40 or 5W-30 synthetic oil for most engines. Specific API service classification and VW/Audi approvals are detailed in the manual.
Coolant Type:
G12 (pink) or G12+ coolant (ethylene glycol-based) is typically recommended for these models.
Transmission Fluid Manual:
API GL-4 or GL-5 gear oil, specific viscosity (e.g., 75W-90) and type specified in the manual.
Transmission Fluid Automatic:
Audi G 052 162 A1 or equivalent ATF fluid, specific type depending on the transmission model (e.g., 5HP19FL).
Common 1 8T Issues:
PCV system failures (leading to oil leaks and rough running), coil pack failures, oil sludge buildup (if maintenance is neglected), catalytic converter issues.
Common V6 Issues:
Timing belt tensioner failure (critical), coolant flange leaks, oil leaks (e.g., valve cover gaskets, oil pan gasket).
Suspension Issues:
Worn control arm bushings, tie rod ends, and wheel bearings are common wear items due to the vehicle's sporty handling and suspension design.
Audi Reputation:
