Engine Options 1995 A4 B5
Specific Gasoline Engines Covered:
1.6L (ADP), 1.8L 20V (ADR), 2.4L V6 (AGA), 2.8L V6 (AAH/ACK). The 1.8T was introduced later in the B5 generation.
Specific Diesel Engines Covered:
1.9L TDI (AHU/AFN/AVG).
Oil Change Interval:
Typically every 15,000 km (9,300 miles) or 12 months, whichever comes first, with synthetic oil. Refer to manual for exact recommendation based on engine and driving conditions.
Timing Belt Replacement:
Crucial for non-interference engines. Typically every 90,000 km (56,000 miles) or 5 years. Interference engines require replacement to prevent catastrophic damage. Manual will specify for each engine type.
Engine Oil Type:
Depends on engine, but typically fully synthetic 5W-40 or 5W-30 meeting VW 500.00 or 502.00 specifications. Manual provides exact grades and capacities.
Coolant Type:
G12 or G12+ coolant (pink) or equivalent. Audi recommends a specific mix ratio with distilled water. Manual will provide part numbers and specifications.
Brake Fluid Type:
