Replace with every oil change.

Air Filter Replacement:

Inspect every 15,000 miles (24,000 km), replace as needed or every 30,000 miles (48,000 km).

Spark Plug Replacement:

Replace every 30,000-60,000 miles (48,000-96,000 km) depending on type (copper vs. platinum). The manual will specify exact intervals and types.

Timing Belt Replacement:

Crucial item for B6 and BP engines. Typically recommended every 60,000 miles (96,000 km) or 4-5 years. Failure can cause severe engine damage (interference engine).

Engine Oil Type:

DOT 3 or DOT 4 brake fluid. Capacities vary, typically less than 1 quart.

Engine Mounts:

Wear and tear can lead to excessive vibration felt in the cabin, particularly when accelerating or decelerating.

Cv Axle Boots:

Torn boots can lead to grease leakage and premature wear of the CV joints, resulting in clicking noises during turns.

Rear Wheel Bearings:

Can develop a humming or grinding noise that increases with vehicle speed, particularly a common issue on the rear.

Cooling System Leaks:

Hoses, radiator, and water pump can develop leaks over time, requiring inspection and replacement.

Corrosion:

As with many vehicles of this era, rust can be an issue in certain climates, particularly around wheel wells, rocker panels, and the subframe.

Ignition System:

Distributor cap, rotor, spark plug wires, and ignition coils can fail over time, leading to misfires or no-start conditions.
