🛡️ Safety Features

Crash Test Data:

Limited publicly available data for this era, but Audi was known for its safety engineering. The B3 platform featured a more rigid chassis and improved safety cell.

ABS:

Optional Anti-lock Braking System (ABS) on higher-spec models.

Airbags:

Driver airbag was optional/standard on some later models of the B3 generation, not standard on all 1990 models.

Seat Belts:

Standard front seat belts, rear seat belts often standard. Pre-tensioners may have been optional.

💡 Technology Features

Audio System:

Factory fitted radio cassette players, often with optional CD changers. Speaker systems varied by trim level.

Climate Control:

Manual or semi-automatic climate control systems were available, with detailed procedures for refrigerant, compressor, and blower motor service.

Cruise Control:

Optional cruise control system available on some models.

Original Connectivity:

Limited to factory radio and speaker systems. No modern connectivity features like Bluetooth or USB were standard.

🔧 Maintenance

Oil Change Interval Km:

Typically every 7,500 - 10,000 km or 6-12 months (depending on oil type and driving conditions).

Timing Belt Replacement Km:

Recommended every 60,000 - 90,000 km or 4-5 years, crucial due to interference engine design on some variants.

Engine Oil Spec:

API SG/SH, ACEA A2/A3, viscosity typically 5W-40, 10W-40, or 15W-40 depending on ambient temperature.

Coolant Spec:

G11 (VAG specification) or equivalent ethylene glycol based coolant with corrosion inhibitors. Mix 50/50 with distilled water.

Brake Fluid Spec:

DOT 4

Transmission Fluid Manual:

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

Transmission Fluid Automatic:

G009300 or equivalent ATF (Automatic Transmission Fluid).

Corrosion:

While the B3 generation featured galvanized bodies, rust can still occur in wheel wells, sills, and around windows over time. The manual will detail inspection points.

Fuel Injection System:

Bosch CIS-E/KE-Jetronic systems can develop issues with air flow meters, fuel distributors, and cold start valves, requiring careful diagnosis covered in the manual.

Suspension Components:

Worn control arm bushings, ball joints, and tie rod ends are common wear items on vehicles of this age.

Electrical Gremlins:

Older wiring can degrade, leading to intermittent issues with lights, gauges, and sensors. Detailed wiring diagrams are essential for troubleshooting.
