Coolant Type:
G12 (Glysantin G30 or equivalent purple coolant) recommended, typically a 50/50 mix with distilled water.
Oil Specification:
Refer to manual for specific API classifications and viscosities (e.g., SAE 5W-40 or 10W-40, often with VW 500.00 or 502.00 approval).
Identification:
Manual will detail engine identification codes and their associated specifications (e.g., ABK, ACE for 2.0L; AAH, ACZ for 2.8L).
Type:
5-speed Manual Transmission.
Type:
4-speed Automatic Transmission (e.g., Audi 01N).
Drivetrain:
Available in Front-Wheel Drive (FWD) and Audi's legendary quattro All-Wheel Drive (AWD).
Fluid Specification Manual
Fluid:
Manual gearbox oil specification (e.g., GL-4 or GL-5 rated gear oil, 75W-90 viscosity typically).
Fluid Specification Automatic
Fluid:
Automatic transmission fluid (ATF) specification, likely a Type T-IV or equivalent (e.g., G 052 162 A1/A2).
Crash Test Results:
Refer to manual for specific structural information. Generally, B4 chassis had good crashworthiness for its era, with crumple zones and reinforced safety cage.
ABS:
Anti-lock Braking System (ABS) available on most models.
Traction Control:
Traction Control System (ASR) may be available on some quattro models.
Airbags:
Driver's airbag standard, passenger airbag optional on later models.
Seatbelts:
Pre-tensioned seatbelts in the front.
Oil Change Interval:
Typically 10,000-15,000 km (6,000-9,000 miles) or 12 months, whichever comes first, depending on driving conditions and oil specification used. Consult manual for specific intervals based on engine and oil type.
Service Intervals Filters
Filter Replacement:
Oil filter with every oil change. Air filter and cabin filter typically every 20,000-40,000 km (12,000-25,000 miles).
Service Intervals Timing Belt
Timing Belt Replacement:
Critical: Typically every 60,000-90,000 km (37,000-56,000 miles) or 5-7 years for interference engines. Failure can cause severe engine damage.
