Audi 80 (B3): A Comprehensive Guide

The Audi 80, particularly the B3 generation, represents a significant chapter in Audi's history. Produced from 1986 to 1991 (and continuing as the Audi 90 with some upgrades), the B3 was a compact executive car that solidified Audi's reputation for quality engineering and innovative design. It belonged to the mid-size sedan segment, competing with cars like the BMW E30 and Mercedes-Benz W201 (190E).

Generations

  • Audi 80 B3 (1986-1991): This generation is the focus of this guide. Key features included its fully galvanized body (a huge selling point), advanced aerodynamics for its time, and a range of fuel-efficient and reliable engines. The 'Procon-ten' safety system was also introduced. A notable variant was the Audi 90, which featured higher-spec engines and trim.

Reliability & Common Issues

The Audi 80 B3 generally enjoys a good reputation for reliability, particularly its rust resistance due to the full galvanization. However, like any car of its age, certain issues are prevalent:

Engine Issues:

  • Fuel Injection Problems (Especially KE-Jetronic): The KE-Jetronic mechanical fuel injection system, used on many B3 models, can be complex and prone to issues. Problems include difficulty starting, rough idling, and poor fuel economy. Diagnosis requires specialized knowledge and tools. Replacement parts can be expensive and sometimes difficult to source. Swapping to a more modern fuel injection system is a possible, although costly, solution.
  • Cooling System Leaks: Check the radiator, hoses, water pump, and thermostat housing for leaks. Overheating can severely damage the engine. Regular coolant flushes and proactive replacement of aged components are crucial.
  • Oil Leaks: Common leak points include the valve cover gasket, oil pan gasket, and crankshaft seals. While not always critical, oil leaks should be addressed to prevent further issues and potential environmental concerns.
  • Timing Belt Replacement (If Applicable): Certain engines, like the 2.0L four-cylinder, use a timing belt. Adhering strictly to the recommended replacement intervals is essential to prevent catastrophic engine damage. Consider replacing the water pump at the same time.

Transmission Issues:

  • Automatic Transmission Problems (If Applicable): The automatic transmissions used in the B3 can suffer from wear and tear over time. Symptoms include slipping gears, harsh shifting, and failure to engage. Fluid changes at shorter intervals than recommended can help extend their lifespan. Rebuilds can be expensive.
  • Manual Transmission Wear: Check for smooth gear engagement and excessive noise. Clutch wear is also a factor to consider, especially in higher mileage examples.

Suspension & Steering:

  • Worn Suspension Components: Expect to replace bushings, ball joints, and shock absorbers due to age and mileage. This can affect handling and ride quality.
  • Power Steering Issues: Check for leaks and unusual noises from the power steering pump. The power steering rack can also develop leaks over time.

Electrical Issues:

  • Wiring Harness Deterioration: The insulation on older wiring can become brittle and crack, leading to shorts and electrical problems. Pay close attention to any electrical malfunctions and inspect wiring harnesses for damage.
  • Central Locking System Problems: The central locking system can be prone to malfunctions, particularly due to corroded contacts or faulty actuators.

Body & Interior:

  • Despite Galvanization, Check for Rust: While the B3 is generally resistant to rust, inspect areas prone to damage such as the wheel arches, sills, and around the fuel filler cap, especially on cars that have been poorly maintained or repaired.
  • Interior Wear and Tear: Expect wear on the upholstery, carpets, and dashboard. Check for cracks and damage to the trim pieces.

Driving Experience

The Audi 80 B3 offers a unique driving experience that combines German engineering with a focus on comfort and refinement. It's not a sports car, but it provides a solid and composed feel on the road.

Pros:

  • Solid Build Quality: The B3 feels well-built and durable, even by today's standards.
  • Comfortable Ride: The suspension is tuned for comfort, making it a pleasant car for long journeys.
  • Fuel Efficiency (Depending on Engine): The smaller displacement engines can offer decent fuel economy.
  • Distinctive Styling: The B3 has a clean and timeless design that still looks good today.
  • Relatively Simple Mechanics: Compared to modern cars, the B3 is relatively straightforward to work on, making it appealing to DIY mechanics.

Cons:

  • Performance: The base models can feel underpowered, especially with the automatic transmission.
  • Age: The car's age means that finding parts can sometimes be challenging, and some components may be nearing the end of their lifespan.
  • KE-Jetronic Issues: The aforementioned KE-Jetronic fuel injection system can be a source of frustration.
  • Availability: Finding a well-maintained example can require patience.

Buying Advice

If you're considering buying an Audi 80 B3, here's some advice:

What Years to Look For:

  • Later Production Years (1989-1991): These models often benefit from minor improvements and refinements over earlier versions.
  • Audi 90 Models: The Audi 90 offers a more powerful engine and generally higher trim levels.

What to Avoid:

  • Cars with Extensive Rust: While galvanized, significant rust indicates poor maintenance or accident damage. Avoid these unless you're prepared for extensive bodywork.
  • Models with Major Mechanical Issues: Engines with excessive smoke, unusual noises, or difficulty starting should be avoided unless you're prepared for a major overhaul.
  • Cars with Poor Maintenance Records: A well-documented service history is crucial. Look for evidence of regular oil changes, timing belt replacements (if applicable), and other preventative maintenance.

Pre-Purchase Inspection:

  • Thoroughly Inspect the Engine: Check for leaks, unusual noises, and smooth running. Pay close attention to the condition of the fuel injection system.
  • Check the Transmission: Test the transmission for smooth shifting and proper engagement.
  • Inspect the Suspension: Look for worn bushings, leaks from the shock absorbers, and signs of damage.
  • Examine the Bodywork: Carefully inspect for rust, dents, and signs of accident repair.
  • Test All Electrical Systems: Ensure that all lights, gauges, and accessories are working correctly.
  • Get a Pre-Purchase Inspection: If possible, have a qualified mechanic inspect the car before you buy it.

The Audi 80 B3 can be a rewarding classic car to own. With careful selection and proper maintenance, it can provide years of reliable service and a unique driving experience. Just be prepared for the challenges that come with owning an older vehicle.
