Carburetor:
Less common in later models, but present in some early variants.
Oil Change Interval:
Typically every 5,000-7,500 miles (8,000-12,000 km) or 6-12 months, depending on driving conditions and oil used. Consult manual for specific recommendations.
Timing Belt Replacement:
Crucial for many petrol engines. Interval typically around 40,000-60,000 miles (60,000-100,000 km) or 4-5 years. Failure can cause catastrophic engine damage.
Engine Oil:
API SG or SH, viscosity typically 10W-40 or 5W-40 synthetic. Specific recommendations vary by engine and climate. Consult manual for exact specification (e.g., VW 500.00).
Coolant:
Ethylene glycol-based antifreeze. Typically a 50/50 mix with distilled water. Specific Audi or VW coolant specifications should be followed.
Transmission Fluid:
Manual: GL-4 or GL-5 gear oil (specific viscosity depends on temperature). Automatic: ATF Dexron II or equivalent (check transmission type).
Fuel Injection System:
