Audi 80 (B4): A Comprehensive Buyer's Guide
The Audi 80, particularly the B4 generation, represents a sweet spot in Audi's history. It's a compact executive car, blending build quality, refinement, and a touch of understated elegance. Produced between 1991 and 1996 (and continuing in other markets as the Audi A4 B5), the B4 offers a classic Audi experience without the complexity and potential pitfalls of later models. It occupies a space just above the small family car segment, offering more space and luxury.
Generations
- B1 (1972-1978): The original Audi 80, a revolutionary car for its time with lightweight construction and efficient engines. Not the focus of this guide.
- B2 (1978-1986): Notable for the introduction of quattro all-wheel drive, which became a defining feature for Audi. Not the focus of this guide.
- B3 (1986-1991): Improved aerodynamics and safety features. Carried over many mechanical components into the B4. Not the focus of this guide.
-
B4 (1991-1996): The model we are focusing on. This generation saw significant refinements over the B3, including a new body style, upgraded interior, and improved suspension. Crucially, it bridged the gap to the A4. It was also sold as the Audi 90 in some markets, featuring upgraded standard equipment.
- Key Changes: Improved corrosion resistance, revised rear suspension, updated interior design, optional quattro all-wheel drive, and introduction of the Cabriolet version. The B4's styling is more rounded and modern compared to the B3.
Reliability & Common Issues
The Audi 80 B4 is generally considered a reliable car, especially compared to more modern vehicles. However, being an older vehicle, it's crucial to be aware of potential issues:
Engine
- Timing Belt: Critical for all engines (except the 1.9 TDI). Must be changed regularly (every 40,000-60,000 miles or every 5 years). Failure can cause catastrophic engine damage. This should be the first question you ask about any potential purchase.
- Cooling System: Overheating is a common problem, often due to radiator leaks, faulty thermostats, or water pump failures. Inspect for coolant leaks and check the coolant level regularly. Plastic coolant flanges are also known to crack with age.
- Oil Leaks: Valve cover gaskets, rear main seal, and oil pan gaskets are prone to leaking. While minor leaks are typical for a car of this age, excessive leaking should be addressed.
- Engine Management System: Check for fault codes. Issues with sensors (especially the mass airflow sensor) can cause poor running.
- 1.9 TDI (Diesel): Generally robust, but check for turbocharger issues (excessive smoke) and injector problems. Diesel engines are susceptible to fuel pump issues.
Transmission
- Manual Transmissions: Generally reliable, but check for smooth shifting and any unusual noises. Clutch wear is inevitable.
- Automatic Transmissions: Can be less reliable than the manuals, especially if not properly maintained. Look for smooth shifting and listen for any unusual noises or slipping. Fluid changes are essential for longevity.
- Quattro System: If equipped, check for proper operation. Listen for any unusual noises from the rear differential or driveshaft. Regular servicing of the differential is crucial.
Suspension & Brakes
- Suspension Components: Bushings, ball joints, and shock absorbers will likely need replacement at some point. Listen for clunking noises when driving over bumps.
- Brakes: Check for warped rotors, worn brake pads, and leaks in the brake lines. ABS systems, if equipped, can be problematic.
Electrical System
- Central Locking System: Can be prone to failure, especially the vacuum-operated system.
- Window Regulators: Often fail, causing the windows to drop.
- Wiring: Check for brittle or damaged wiring, especially in the engine bay.
Body & Interior
- Rust: While the B4 has improved corrosion resistance compared to earlier models, rust can still be an issue, especially in areas prone to water accumulation (wheel arches, sills, underbody). Thoroughly inspect the car for rust before purchasing.
- Interior: Check for wear and tear on the seats, carpets, and dashboard. Sun damage can cause cracking and fading. The plastic components can become brittle with age.
Driving Experience
The Audi 80 B4 offers a refined and comfortable driving experience. The steering is precise and well-weighted, and the suspension provides a good balance between comfort and handling. The quattro system, when equipped, provides excellent traction and stability in all weather conditions.
Pros:
- Solid build quality
- Comfortable ride
- Precise handling
- Available quattro all-wheel drive
- Understated and timeless styling
Cons:
- Age-related reliability issues
- Potential for rust
- Performance can be underwhelming with smaller engines
- Parts can be difficult and/or expensive to find, depending on the specific part.
Buying Advice
Years to Look For:
- Later Years (1994-1996): Generally benefit from improvements made throughout the production run.
- Cars with Detailed Service History: A well-maintained example is always preferable. Pay close attention to timing belt replacement records.
What to Avoid:
- Cars with Significant Rust: Repairing rust can be expensive and time-consuming.
- Cars with Major Mechanical Issues: Unless you are a skilled mechanic, avoid cars with significant engine or transmission problems.
- Cars with Neglected Maintenance: Look for signs of neglect, such as worn tires, dirty engine bay, and missing service records.
Engine Choices:
- 1.9 TDI: A reliable and fuel-efficient option, offering decent performance for everyday driving.
- 2.0 (8V/16V): A good compromise between performance and economy. The 16V engine offers slightly more power.
- 2.6/2.8 V6: Provides more power and a smoother driving experience, but fuel economy is lower and maintenance costs are higher.
Final Thoughts:
The Audi 80 B4 is a classic car that offers a lot for the money. With careful inspection and a little bit of maintenance, it can be a reliable and enjoyable daily driver or weekend cruiser. Be prepared for age-related repairs and factor in the cost of parts and labor when making your decision. A pre-purchase inspection by a qualified mechanic is highly recommended.
