Audi 100 E (1985–1987)

The Audi 100 (C3), produced from 1985 to 1987, marked a significant innovation in Audi's quest for excellence in aerodynamics and construction. While these classics may not be as common in New Zealand as their European counterparts, they exemplify the rich tapestry of German automotive design. Owners appreciate the uncomplicated mechanics, making it an excellent choice for enthusiasts looking to enjoy a classic driving experience with a touch of sophistication.

Parts for the Audi 100 E

Known issues

Common issues on these older Audi 100 models include rust (especially around wheel arches, sills, and the fuel filler), worn suspension components (bushings, ball joints), and issues with the Bosch fuel injection systems. The automatic transmissions, if fitted, can also be prone to problems with age, so check for smooth shifting. Pay close attention to the condition of rubber seals and hoses, as these will likely be brittle and prone to leaks. Also, ensure the cooling system is in good order to avoid overheating, which can be catastrophic for these engines.

WOF tips

When inspecting an Audi 100 for a WOF, pay careful attention to rust in the areas mentioned above. Check all lights are functioning correctly (headlights, taillights, indicators). Suspension components need to be in good condition with no excessive play. Brake lines and hoses must be free of leaks and in good condition. Ensure the tyres meet the minimum tread depth requirements, and the windscreen is free from cracks that could obstruct the driver's vision. Exhaust systems must be leak-free and meet noise emission standards.

About the Audi 100 E

During its production run, the Audi 100 was offered in several variants, including sedans and Avants (wagons). Engine choices featured inline four-cylinder and five-cylinder petrol and diesel options, providing a smooth and comfortable ride ideal for cruising rather than racing. The Quattro all-wheel-drive system was a game-changer for select models, enhancing grip and stability on New Zealand roads. It's important for owners to be mindful of potential issues over time. Common problems include wear in suspension components, such as bushings and ball joints, often requiring replacement to maintain comfort and safety during your drive.

Regular maintenance is crucial, particularly with the cooling system—around the 150,000km mark, components like the water pump, thermostat, and radiator hoses should be inspected to prevent overheating issues, which can lead to serious engine damage. Changing the brake pads and rotors periodically is also recommended to ensure optimal stopping power, especially given the age of the vehicle.
