Engine Variant 1:
2.0L Inline-5 Cylinder (e.g., Audi 100 2.0E)
Engine Variant 2:
2.3L Inline-5 Cylinder (e.g., Audi 100 2.3E)
Engine Variant 3:
2.2L Inline-5 Cylinder Turbocharged (e.g., Audi 200 20V Turbo quattro)
Horsepower Range:
Approximately 115 hp (2.0L) to over 220 hp (2.2L Turbocharged).
Torque Range:
Varies by engine; Turbocharged models offered significantly higher torque figures.
Injection Type:
Bosch CIS (Continuous Injection System) or CIS-E (Electronic) fuel injection, and Motronic for turbocharged models.
Fuel Type:
Unleaded gasoline (Octane rating as per manufacturer's recommendation).
Safety Features Era:
While formal crash test ratings (like NHTSA's STAR system) were less standardized in 1990, Audi emphasized passive safety with features like safety-cell construction, energy-absorbing bumpers, and advanced seat belt systems. ABS was often an option.
Braking System:
Anti-lock Braking System (ABS) was available on most models as an option.
Body Structure:
Reinforced safety cage, crumple zones, side-impact protection beams.
Restraints:
Three-point seat belts with pre-tensioners (depending on market/spec), driver's side airbag (increasingly common in this era).
Oil Change Interval:
Typically every 7,500 to 10,000 miles (12,000 to 16,000 km) or annually, depending on driving conditions. Consult the specific manual for precise intervals.
Timing Belt Replacement:
Crucial service. For most 5-cylinder engines, replacement is typically recommended every 60,000 to 90,000 miles (96,000 to 144,000 km) or 5-7 years. Failure can cause severe engine damage.
Engine Oil:
API SF/SG or ACEA A1/A2, viscosity grade typically 5W-40 or 10W-40, though specific recommendations vary by engine and climate. Check manual for precise spec.
Coolant:
Ethylene glycol based antifreeze, typically a 50/50 mix with distilled water. Specific Audi G11 specification is common for this era.
Brake Fluid:

Transmission Fluid Manual:
API GL-4 or GL-5 gear oil, viscosity typically 75W-90 or 80W-90.
Transmission Fluid Automatic:
ATF Dexron III (or equivalent specified by Audi).
Common Issues:
Timing belt failure (if not replaced on schedule), vacuum hose deterioration leading to idle/performance issues, fuel distributor leaks (CIS systems), electrical gremlins, water pump failure, ABS sensor issues, and potential rust in certain areas (wheel arches, sills).
Heritage:
Audi, a member of the Volkswagen Group, has a long history of engineering innovation, particularly in quattro all-wheel drive technology and forward-thinking design.
C3 Generation:
The C3 (Type 44) platform, launched in 1982, was a significant departure for Audi, featuring advanced aerodynamics, galvanized bodies for corrosion resistance, and the introduction of the influential quattro all-wheel-drive system across a wider range of models.
100 Vs 200:
The 100 served as the mainstream executive model, while the 200 was positioned as the more luxurious and performance-oriented variant, often featuring turbocharging and higher trim levels.
Production Years:
The C3 generation was produced from 1982 to 1991. The 1990 model year falls within the later, refined years of this generation.
