Injection Type:
Fuel injection (Bosch Motronic or similar electronic fuel injection systems) across most variants.
Common Engine Codes:
e.g., ABT (2.0L 8v), ACE (2.0L 16v), AAZ (1.9 TD), ABC (2.6L V6), ACK (2.8L V6) - specific codes are detailed within the manual.
Crash Test Notes:
While formal Euro NCAP ratings were less standardized in 1992, the B4 chassis was known for a robust construction typical of German engineering of the era.
Available Safety Features:
Anti-lock Braking System (ABS), quattro all-wheel drive.
Standard Safety Features:
Front seatbelts, reinforced passenger cell, side impact beams.
Audio System:
Factory fitted radio/cassette players with basic speaker systems. Options for CD changers might have been available. Manual will cover radio code procedures and basic component removal.
Assist Systems:
ABS was the primary driver assistance system. Cruise control was an optional feature on many models.
Connectivity Features:
Minimal by modern standards. Features would include basic external antenna for radio. No integrated Bluetooth or USB connectivity.
HVAC Features:
Manual climate control or optional automatic climate control (Climatronic) on higher trims. Manual covers system operation and maintenance.
Oil Change Interval:
Typically every 10,000-15,000 km (6,000-9,000 miles) or annually, depending on driving conditions and oil used. The manual will specify exact intervals.
Timing Belt Interval:
Crucial maintenance item. For most gasoline engines, this is usually around 80,000-120,000 km (50,000-75,000 miles) or every 5-7 years. Refer to the manual for specific engine recommendations.
Engine Oil Type:
API SG/SH or ACEA A2/A3 specifications. Viscosity grades like 5W-40 or 10W-40 are common. The manual will list precise specifications and capacities for each engine.
Coolant Type:
Ethylene glycol based coolant (e.g., G11 specification, often blue or green). Manual will specify mix ratio and capacity.
Brake Fluid Type:
DOT 3 or DOT 4. Manual will specify type and replacement interval.
Common Wear Items:
Suspension bushings (control arms, sway bars), CV joints (especially on quattro models), coolant flanges (prone to cracking), window regulators, and minor electrical gremlins (e.g., central locking, window motors).
Engine Specific Concerns:
Some early 2.0L engines could be prone to oil consumption; exhaust manifold gaskets can fail. Timing belt tensioner and idler pulley failure is critical and should be replaced with the belt.
OBD System:
OBD-I (On-Board Diagnostics I) system, typically accessed via a proprietary Audi connector, requiring specific scan tools or jumper wire procedures for fault code retrieval. The manual will detail these procedures.
Audi Heritage Highlights:
Long history of engineering innovation, particularly with quattro all-wheel drive and advanced four-cylinder engines.
B4 Generation Context:
The B4 (Type 8C) represented a significant modernization of the Audi 80 lineage, featuring updated styling, improved aerodynamics, and chassis enhancements over its B3 predecessor.
Production Years:
1991-1996 (for the B4 generation).
Assembly Plants:
Mainly Ingolstadt, Germany.
Industry Awards Or Notes:
The Audi 80/90 series, including the B4, was often praised for its sophisticated engineering, comfortable ride, and the performance benefits of its quattro system, contributing to Audi's growing reputation for premium vehicles in the early 1990s.
