🔧 Maintenance

Oil Change:

Typically every 5,000 - 7,500 miles (8,000 - 12,000 km) or 6-12 months, depending on driving conditions.

Spark Plugs:

Every 20,000 - 30,000 miles (32,000 - 48,000 km), depending on plug type.

Timing Belt:

Crucial for interference engines. Typically every 40,000 - 60,000 miles (64,000 - 96,000 km) or 4-5 years. Replacement is critical to prevent catastrophic engine damage.

Engine Oil:

SAE 10W-40 or 15W-40 API SF or SG rated oil (check manual for exact specification and viscosity based on ambient temperature).

Coolant:

Ethylene glycol based antifreeze mixed with distilled water in a 50/50 ratio. Audi-approved coolant recommended.

Brake Fluid:

DOT 3 or DOT 4 (refer to manual for specific approval).

Fuel System Reliability:

K-Jetronic systems can become sensitive to vacuum leaks and fuel pressure regulator issues, requiring careful diagnosis.
