🛡️ Safety Features

Safety Ratings Era:

While specific crash test data for the 1992 model may vary by region (e.g., Euro NCAP was nascent), Audi prioritized safety with features like a robust unibody construction, side-impact beams, and safety-optimized crumple zones.

Active Safety Features:

Anti-lock Braking System (ABS) often optional or standard on higher trims, power-assisted steering.

Passive Safety Features:

Front airbags (driver and passenger often optional on earlier models, becoming more standard), three-point seatbelts with pre-tensioners, safety-padded interior, energy-absorbing steering column.

💡 Technology Features

Infotainment Systems:

Factory-fitted radio/cassette players, often with optional CD changers. Speaker systems varied by trim level. Basic analog instrumentation.

Driver Assistance Features:

ABS was an option. No electronic stability control or advanced driver-assistance systems (ADAS) were available on this model. Power steering was standard.

Connectivity Features:

No integrated Bluetooth or smartphone connectivity. Aftermarket solutions were the only way to add such features.

🔧 Maintenance

Oil Change Interval:

Typically every 15,000 km or 12 months, whichever comes first (subject to driving conditions; consult manual for specifics).

Timing Belt Replacement:

Crucial for 4-cylinder engines. Interval generally around 60,000-90,000 km or 4-5 years. For 5-cylinder engines, it was often a timing chain or belt with longer intervals, but verification is key. Consult manual for specific engine code intervals.

Engine Oil Specification:

API SG/SH or ACEA A2/A3. Viscosity typically 5W-40, 10W-40, or 15W-40 depending on climate and manufacturer recommendation. Consult manual for exact specification.

Coolant Specification:

G11 (blue/green) or G12 (pink/red) ethylene glycol-based antifreeze, mixed 50/50 with distilled water.

Brake Fluid Specification:

DOT 3 or DOT 4.

Transmission Fluid Manual:

API GL-4 or GL-5 gear oil, SAE 75W-90 or 80W-90.

Transmission Fluid Automatic:

G009300 or equivalent ATF fluid (e.g., Dexron II/III).

Power Steering Fluid:

G002000 or equivalent Pentosin CHF 11S/202.

Clutch Fluid Specification:

DOT 3 or DOT 4 brake fluid (for hydraulic clutch systems).

Common Issues:

Degradation of plastic/rubber components (hoses, seals, intake manifold gaskets), ABS sensor failures, window regulator mechanisms, ignition coil failure, suspension wear (bushings, ball joints), fuel pump issues, heater core leaks, rust (particularly around wheel arches, sills, and door bottoms).

Timing Belt Risk:

Interference engine design for most 4-cylinder variants; failure of the timing belt can cause catastrophic engine damage. Strict adherence to replacement intervals is critical.

Interior Wear:

Worn driver's seat bolsters, sagging headliner, and faded dashboard materials are common due to age and UV exposure.

Fuel System Issues:

Clogged fuel injectors, failing fuel pumps, and leaking fuel lines can occur.
