Common Engine Options 1989 1991:
2.0L (1984cc) I5 (Naturally Aspirated and Turbocharged), 2.3L (2309cc) I5 (Naturally Aspirated and Turbocharged), 2.5L (2461cc) V6 (Naturally Aspirated), 2.6L (2600cc) I5 (Naturally Aspirated - likely for later models/specific markets), 4.2L (4172cc) V8 (Audi V8 - some C4 platform elements shared)
Horsepower Torque Variations:
Horsepower and torque figures varied significantly across engine options and turbocharging, ranging from approximately 100 hp to over 200 hp for naturally aspirated and 200+ hp for turbocharged variants.
Fuel Delivery:
Fuel injection (e.g., Bosch KE-Jetronic, Motronic) depending on engine and year.
Oil Change Interval:
Typically every 5,000-7,500 miles or 6-12 months, depending on driving conditions and oil type used. Check manual for specific recommendations.
Timing Belt Replacement:
For 5-cylinder engines, timing belt replacement is crucial, typically around 60,000-90,000 miles. V6 engines may have different intervals or chain-driven systems.
Engine Oil Type:
Refer to the manual for specific API ratings and viscosity grades (e.g., 5W-30, 10W-40, 5W-40 for synthetic).
Coolant Type:
Typically a G11 or equivalent ethylene glycol-based coolant. Consult manual for exact specification.
Transmission Fluid:
Specific ATF for automatic transmissions (e.g., Dexron-II or III equivalent) and gear oil for manual transmissions. Exact specifications in manual.
Common Wear Items:
Control arm bushings, tie rod ends, fuel pump, coolant flanges (especially on 5-cylinder engines), window regulators, climate control flaps.
Electrical Gremlins:
Age-related issues with wiring insulation, sensor failures, and relay problems can occur.
Turbocharger Issues:
For turbocharged models, proper maintenance is key to longevity; oil starvation or overheating can cause failure.
Audi Philosophy:
Audi's reputation for engineering, quattro all-wheel drive, and understated luxury.
C3 To C4 Transition:
The period 1989-1991 saw a transition from the C3 (Typ 443) platform to the C4 (Typ 4A) platform. The C4 represented a significant modernization and larger chassis.
Audi 100 Role:
The Audi 100 served as Audi's executive car, offering advanced technology and comfort.
Audi 200 Role:
The Audi 200 was positioned above the 100, typically featuring more powerful engines (often turbocharged) and higher levels of standard equipment.
Production Years:
C3 Audi 100/200: 1982-1991 (model years may differ by market). C4 Audi 100/200: 1990-1994.
