Engine Options:
Likely covers the 2.0L inline-5 (5-cylinder) naturally aspirated engines (e.g., NG, NF, PS codes) and potentially the 2.3L (e.g., NG) or 2.2L turbocharged inline-5 (e.g., G, JT codes) found in the Coupe and Quattro variants of this generation.
Typical Power Output:
Varies by specific engine variant, but typically ranged from 115 hp for naturally aspirated to over 160 hp for turbocharged models.
Fuel Delivery:
Bosch KE-Jetronic (CIS-E) or Digifant electronic fuel injection depending on model and year.
Transmission Type Standard:
Manual transmission (5-speed) was common.
Transmission Type Optional:
Automatic transmission (3-speed or 4-speed) was available on some models.
Drivetrain Options:
Front-wheel drive (FWD) and permanent all-wheel drive (Quattro) were offered.
Safety Era Standards:
Designed to late 1980s safety standards, likely featuring crumple zones, safety-belt pretensioners (on later models), and reinforced door beams. ABS was an optional feature on some later models.
Active Safety:
Four-wheel disc brakes, power-assisted steering, ABS (optional).
Passive Safety:
Seat belts, reinforced body structure, padded interior surfaces.
Audio System:
Factory AM/FM cassette stereo systems were common, with optional CD players available on later models. Speaker configurations varied.
ABS Availability:
Anti-lock Braking System (ABS) was an option, particularly on higher-spec or Quattro models.
Connectivity Features:
Limited connectivity by modern standards. Primarily focused on on-board diagnostics via OBD-I port for engine management.
Oil Change Interval:
Typically every 7,500 to 10,000 miles (12,000 to 16,000 km) or 6-12 months, using appropriate synthetic or semi-synthetic oil.
Timing Belt Replacement:
Critical interval, usually around 60,000 miles (96,000 km) or 5 years. Failure can cause catastrophic engine damage.
Engine Oil Type:
API SG/SH rated, SAE 10W-40 or 15W-40, or as specified by Audi for specific engine codes.
Coolant Type:
Ethylene glycol-based antifreeze, typically G11 (blue) specification, mixed 50/50 with distilled water.
Brake Fluid Type:
DOT 3 or DOT 4 brake fluid.
Transmission Fluid Manual:
API GL-4 or GL-5 gear oil, SAE 75W-90 or 80W-90.
Transmission Fluid Automatic:
Dexron III or equivalent ATF (Automatic Transmission Fluid).
Common Problems:
Fuel distributor diaphragm leaks (CIS-E), worn distributor seals, ignition module failure, cooling fan relay issues, wheel bearing noise, suspension component wear (ball joints, bushings), fuel pump failure, rust in common Audi areas (wheel arches, sills).
Audi Heritage:
Audi has a long history of engineering innovation, particularly in quattro all-wheel-drive systems and inline-5 cylinder engines.
Coupe Evolution:
The Audi Coupe (Typ 89) was part of Audi's 80/90 series platform, known for its sophisticated engineering and sporty styling. It represented Audi's effort to compete in the premium sporty coupe market of the era.
Production Period:
The Typ 89 generation of the Audi Coupe was produced from 1988 to 1991.
