Operating Systems:
All Versions of Windows & Mac
Engine Options:
Inline-5 cylinder gasoline engines (e.g., 2.2L, 2.3L) and potentially turbodiesel engines. Specific engine codes would be detailed within the manual.
Power Output Range:
Varies by specific engine and market (typically 110-170 hp for naturally aspirated, higher for turbo models like the 200).
Torque Output Range:
Varies by specific engine and market.
Fuel Delivery:
Likely Bosch K-Jetronic (CIS) mechanical fuel injection for gasoline engines, potentially with turbocharger integration on 200 models. Diesel would have rotary or in-line injection pumps.
Ignition System:
Electronic ignition system with distributor.
Emission Controls:
Catalytic converter (depending on market), air injection system (potentially).
Transmission Types:
5-speed manual transmission and 3-speed automatic transmission (likely ZF).
Drivetrain Options:
Front-wheel drive (FWD) and permanent all-wheel drive (Quattro).
Clutch Type:
Hydraulically actuated single-plate dry clutch for manual transmissions.
Manual Transmission Fluid:
API GL-4, SAE 75W-90 or similar (specific Audi spec would be in manual).
Automatic Transmission Fluid:
Type T-III or similar Dexron-compatible ATF (specific Audi spec would be in manual).
Crash Test Results:
No standardized crash ratings as we know them today were widely published for vehicles of this era. However, the C3 platform was known for its robust construction.
Braking System:
Front ventilated discs, rear solid discs. Optional Anti-lock Braking System (ABS) on later models or specific trims of the 1983 model year.
Seatbelts:
Front and rear seatbelts. Pre-tensioners were not standard.
Chassis Design:
Unibody construction with integrated safety cage.
Oil Change Interval:
Typically every 5,000-7,500 miles (8,000-12,000 km) or 6-12 months, depending on driving conditions and oil type.
Timing Belt Interval:
Approximately 60,000 miles (100,000 km) for inline-5 engines (crucial to check and replace if interval is due).
Engine Oil Grade:
API SF/SG, SAE 10W-40 or 15W-50, depending on climate. Synthetic oils recommended for better protection.
Coolant Type:
Ethylene glycol based, typically a 50/50 mix with distilled water. Specific Audi coolant type (e.g., G11) would be specified.
Brake Fluid:
DOT 3 or DOT 4 (check reservoir cap or manual for exact specification).
Common Wear Items:
Suspension bushings, CV joints (especially on Quattro models), fuel distributors (K-Jetronic), aging rubber hoses and seals, O2 sensors (if equipped), exhaust system components.
Electrical Faults:
Corrosion in wiring harnesses, failing relays, dashboard instrument cluster issues, and headlight switch problems can occur due to age.
Audi Philosophy:
Known for advanced engineering, quattro all-wheel drive, and sophisticated design.
C3 Generation:
The C3 generation (introduced in late 1982 for the 1983 model year) was a significant redesign, featuring a highly aerodynamic exterior (drag coefficient as low as 0.30) and pioneering features like the Procon-10 safety system (though it might have been optional or introduced later).
Manufacturing Location:
Germany (Ingolstadt)
Aerodynamic Design:
The C3 generation was highly lauded for its advanced aerodynamic design, contributing to fuel efficiency and reduced wind noise, which was a significant achievement for its time.
Procon 10 System:
While possibly introduced in 1984 or later, the Procon-10 safety system (a mechanical system that tensioned seatbelts in a collision) was a pioneering safety technology from Audi around this period.
