The Audi 100 (C4 generation, 1991-1994) retains a special place in the Audi legacy. With its superior build quality and sophisticated design language, it was not just a car but a glimpse into the future of the Audi brand. Today, in New Zealand, the Audi 100 is celebrated as a classic vehicle, appealing to those who appreciate its heritage and the driving pleasures it provides. However, ownership comes with responsibilities, and understanding how to care for this remarkable machine is essential.
Common issues with the Audi 100 include: 1. Electrical problems: Wiring can become brittle and connectors corroded, leading to intermittent faults. Central locking systems and electric window mechanisms are often problematic. 2. Cooling System: Radiators, hoses and water pumps can fail due to age. Overheating can cause significant engine damage, so proactive maintenance is vital. 3. Suspension wear: Bushings, ball joints, and shock absorbers will likely require replacement. Listen for clunking noises over bumps. 4. Quattro system (if equipped): The all-wheel-drive system is robust, but can suffer from worn viscous couplings or differential issues. 5. Fuel system: Fuel pumps and injectors can become clogged or fail after many years of service.
When it comes to WOF inspections, key areas of concern include: 1. Suspension: Check for excessive play in ball joints, worn bushings, and leaking shock absorbers. 2. Brakes: Inspect brake pads, rotors, and hoses for wear and leaks. The handbrake mechanism should also be checked. 3. Lights: Ensure all lights are functioning correctly, including headlights, taillights, brake lights, and indicators. 4. Tyres: Check for correct tread depth and any signs of damage. 5. Rust: Although body is galvanized, check body thoroughly for rust. Any structural rust will cause a failure. 6. Steering: Power steering leaks are very common, so check carefully.
Constructed with a galvanised steel chassis, the Audi 100 provides excellent rust resistance, but as it approaches 30 years of age, proactive maintenance cannot be overlooked. Engine options typically range from inline-four to V6 petrol engines and diesel variants. Additionally, those who opted for the Quattro system revel in its unmatched grip and performance in diverse driving conditions.
As with any classic car, common issues tend to arise. Electrical problems, such as brittle wiring and corroded connectors, are not uncommon, especially with the central locking and electric windows. Regular inspections are advised to catch these early, particularly for the electrical system every 50,000km. The cooling system, integral to engine longevity, requires special attention around the 150,000km mark. Parts such as the water pump, thermostat, and radiator may need to be replaced to prevent overheating.

Furthermore, worn suspension components, including bushings and shock absorbers, often need attention to maintain ride quality. Listen for clunking sounds over bumps, and be prepared to replace these components as they wear.
