Automatic Transmission Features:
Electronic control, sport/economy modes may be present.
Safety Ratings Era Context:
Information for this era is less standardized than modern tests. Focus would be on passive safety features and structural integrity as per European NCAP or equivalent standards of the time.
Active Safety Features:
Optional Anti-lock Braking System (ABS) on some models.
Passive Safety Features:
Frontal airbags (driver and passenger), reinforced chassis, crumple zones, seatbelt pretensioners.
Infotainment Features:
AM/FM radio, cassette player, optional CD player. Basic climate controls (manual or automatic climate control).
Driver Assistance Features:
Primarily ABS if optioned. Limited advanced driver-assistance systems for the era.
Connectivity Features:
N/A (No integrated Bluetooth or modern connectivity features).
Oil Change Interval:
Typically every 10,000 km (6,200 miles) or 12 months, whichever comes first, using synthetic oil.
Timing Belt Replacement:
Crucial! Every 60,000 - 90,000 km (37,000 - 56,000 miles) or 5 years, whichever comes first. Failure results in catastrophic engine damage.
Engine Oil Specification:
API SG/SH rated, SAE 5W-40 or 10W-40 synthetic oil.
Coolant Specification:
G11 (Glysantin G48 or equivalent) silicate-based coolant, typically a 50/50 mix with distilled water.
Brake Fluid Specification:
DOT 4 or DOT 3, low-viscosity synthetic.
Transmission Fluid Manual:
GL-4 SAE 75W-90 or 80W-90 gear oil.
Transmission Fluid Automatic:
Dexron III (or equivalent ATF specification).
Common Wear Items:
CV boots, suspension bushings, wheel bearings, heater core, fuel distributor diaphragm, O2 sensors.
Electrical Issues:
Corrosion in connectors, failing climate control units, aged wiring insulation.
Engine Maintenance Considerations:
Strict adherence to timing belt replacement is paramount. CIS-E/KE-Jetronic systems can be sensitive to air leaks and require careful adjustment.
Audi Brand Reputation:
Known for engineering excellence, quattro all-wheel drive technology, and sophisticated design.
Audi 90 B3 Context:
The Type 85/89 generation represented Audi's push into the premium compact segment, building on the success of the Audi 80. The '93 model is part of the mid-cycle updates for this generation.
Production Years For B3 Generation:
1986-1991 (for the initial B3), with variants and updates extending into the early 90s for certain markets, and the platform evolving into the B4 generation shortly after.
