Engine Options B3:
The B3 platform supported a range of Audi's inline-4 and V6 engines. Common engines included the 1.6L (EZ, PP), 1.8L (JN, RP, PM, RU, NE, SF, RT), 2.0L (2E, AAD, ACU, ABK), and 2.3L (NG, AAR). Specific engine codes will be detailed within the manual.
Power Output Range:
Horsepower typically ranged from approximately 75 hp (1.6L) to 137 hp (2.3L 20V, though the manual primarily covers 10v models up to 130hp).
Torque Range:
Torque figures varied significantly by engine, with ranges from around 130 Nm to over 180 Nm.
Fuel Delivery:
Primarily fuel injection (K-Jetronic, KE-Jetronic, or Digifant depending on engine and year). Carbureted models may exist in earlier export markets but are less common for this generation's core coverage.
ECM Systems:
Details on various Bosch Motronic or similar engine control units (ECU) will be covered.
Crash Test Results:
Specific official ratings from agencies like Euro NCAP or NHTSA for these specific years are not readily available or may be outdated by modern standards. The manual will detail the vehicle's safety systems as designed.
Braking System:
Front disc brakes, rear drum brakes standard on most models. Higher-performance variants or later models may feature rear discs.
Airbags:
Driver airbag was optional or standard on later models. Passenger airbags were not common for this generation.
Seatbelts:
Front and rear seat belts, with pre-tensioners often available or standard on later production years.
Oil Change Interval:
Typically 10,000-15,000 km (6,000-9,000 miles) or 12 months, depending on driving conditions and specific oil used. Consult manual for exact recommendations.
Timing Belt Replacement:
Crucial for interference engines. Generally recommended every 60,000-90,000 km (37,000-56,000 miles) or 4-5 years. Manual will specify exact interval and part numbers.
Engine Oil Type:
Varies by engine and climate. Common specifications include VW 500 00, 501 01, or 502 00. Viscosities like 5W-40, 10W-40, or 15W-40 were typical. Manual will list precise requirements.
Coolant Type:
G11 (blue/green) coolant or equivalent antifreeze mixed with distilled water. Manual will specify exact type and mixture ratio.
Brake Fluid Type:
DOT 3 or DOT 4 brake fluid. Manual will specify recommended type and replacement interval.
Transmission Fluid Type Manual:
API GL-4 gear oil, typically 75W-90 or 80W-90. Manual will list specific viscosity and capacity.
Transmission Fluid Type Auto:
Dexron II or equivalent ATF. Manual will specify exact type and capacity.
Common Wear Items:
Wear items include suspension components (ball joints, tie rod ends, bushings), CV joints, exhaust systems, fuel pumps, and radiator components. Electrical issues can also arise with age, particularly related to grounds and connectors.
Engine Specific Concerns:
Early fuel injection systems may require periodic cleaning or adjustment. Timing belt failure is critical. Head gasket leaks can occur on higher mileage engines.
Onboard Diagnostics:
OBD-I systems or basic diagnostic codes may be present, detailed in the manual for troubleshooting.
Audi Heritage:
Audi has a long history dating back to the early 20th century, known for engineering and quattro all-wheel drive technology. The Audi 80/90 lineage represents a significant part of Audi's executive compact car segment.
B3 Generation:
The B3 generation (Typ 89) was a significant redesign from the B2, featuring a more aerodynamic and modern exterior design. It introduced the 'Procon-Ten' safety system precursor (a mechanical seatbelt tensioning system) on some models.
Production Period:
1986-1991
