Common Engines 2000S:
Continuation of V6 engines (e.g., 2.4L, 2.8L) and 1.9 TDI diesel variants.
Horsepower Range:
Approximately 75 hp to 174 hp, depending on engine and specific model (e.g., 1.6L to 2.8L V6).
Torque Range:
Approximately 120 Nm to 250 Nm, depending on engine and specific model.
Fuel Delivery Type:
Carburetor (early models) and Electronic Fuel Injection (EFI) across most of the 1990-2006 period. Diesel models utilize various injection pump systems, including common rail for later TDI engines.
Fuel Type:
Unleaded Gasoline (Octane ratings as specified by Audi), Diesel fuel.
Oil Type Recommendation:
Typically API SG, SH, or SJ or ACEA A2/A3 rated synthetic or semi-synthetic oils. Viscosity grades like 5W-30, 5W-40, 10W-40, 10W-30 are common, as per Audi specifications for specific engines and climates. Manual will detail exact specifications and capacities.
Coolant Type:
Ethylene glycol based coolant (G11 or G12 variants typically used). Manual will specify correct type and mixture ratio.
Manual Transmission:
5-speed manual transmissions were standard on many models.
Automatic Transmission:
Optional 4-speed automatic transmissions (e.g., ZF 4HP series) were available on many variants.
Drive Type:
Front-wheel drive (FWD) standard, with Audi's Quattro all-wheel drive (AWD) system available as an option on many models.
Automatic Transmission Fluid:
Specific ATF (e.g., Dexron II, Dexron III, or proprietary Audi specs) required for automatic transmissions. Manual will detail exact type and capacity.
Manual Transmission Fluid:
Gear oil (e.g., GL-4 or GL-5 rated) with specific viscosity grades. Manual will detail exact type and capacity.
Crash Test Results:
Early models from the 1990s would have undergone various national crash test protocols (e.g., Euro NCAP may not have been as comprehensive then). Later models would show improved safety structures. Specific ratings would be detailed in the manual if available from official sources.
ABS:
Anti-lock Braking System (ABS) was an option on many models, standard on higher trims or later production years.
Traction Control:
Traction control systems (ASR) became available on some higher-spec models in later years.
Airbags:
Driver and front passenger airbags became increasingly standard throughout the production run. Side airbags were rare or optional on later models.
Seatbelts:
Three-point inertia-reel seatbelts with pre-tensioners for front occupants, particularly in later models.
Oil And Filter Change:
Typically every 10,000-15,000 km or 12 months, whichever comes first, depending on driving conditions and oil used. Manual will provide exact intervals.
Timing Belt Replacement:
Critical for many engines. Intervals vary by engine type, but common recommendations are between 60,000-100,000 km or 5-7 years. Failure can cause catastrophic engine damage. Manual will specify exact interval and procedure.
Spark Plug Replacement:
Intervals depend on spark plug type (copper, platinum, iridium). Typically 30,000-60,000 km for standard plugs, and potentially longer for premium types. Manual will specify correct type and interval.
Brake Fluid Type:
DOT 4 is a common specification for this era of Audi. Manual will confirm precise DOT rating and change interval.
Power Steering Fluid:
Hydraulic fluid compatible with Audi specifications (often ATF or specific power steering fluid). Manual will specify exact type and capacity.
Common Issue 1:
Corrosion: Particularly on older models, check body panels, subframes, and suspension components for rust.
Common Issue 2:
Suspension Wear: Bushings, ball joints, and tie rod ends can wear over time, leading to poor handling and noise.
Common Issue 3:
Electrical Gremlins: Older wiring harnesses and connectors can degrade, leading to intermittent issues with lights, sensors, or accessories.
Common Issue 4:
Cooling System Leaks: Hoses, radiators, and water pumps are common failure points, especially with age.
Common Issue 5:
Oil Leaks: Valve cover gaskets, oil pan gaskets, and crankshaft seals can develop leaks.
Audi Legacy:
Audi, a German manufacturer, has a long history of producing quality vehicles known for their engineering, technology, and often, Quattro all-wheel drive systems.
Audi 80 Evolution:
The Audi 80 (and its closely related 90 variant) was a series of compact executive cars produced by Audi. It evolved through several generations (B1 to B5), with the 1990-2006 period primarily covering the B3, B4, and the early B5 generations of the Audi 80/A4 lineage. The '90' designation was typically used for higher-spec models, often with more powerful engines (like the 5-cylinder or V6) and more luxurious features.
Transition To A4:
The Audi 80 was effectively replaced by the Audi A4 starting in 1994 (B5 platform), though some markets may have continued with '80' badging for a period. The manual's extended coverage to 2006 implies it might encompass the later B5 A4 platforms that retained some Audi 80 DNA.
Manufacturing Locations:
Primarily Germany (Ingolstadt, Neckarsulm), with potential production in other global facilities.
