Reliability & Common Issues
The Alfa Romeo 166 is known for its attractive design and driving dynamics, but its reliability record is less stellar. Potential buyers should be aware of the following common issues:
Engine Issues:
- Timing Belt Failure (V6 Engines): A poorly maintained timing belt on the V6 engines can lead to catastrophic engine damage. Regular maintenance is crucial. Replace the belt and water pump according to the manufacturer's schedule (typically every 36,000 miles or 3 years).
- Selénia Oil Dependence (V6 Engines): Alfa Romeo engines are specifically designed for Selénia oil. Using other brands can lead to premature wear.
- Spark Plug Coil Failure (V6 Engines): Coil packs are prone to failure, leading to misfires and rough running. Replacement is usually straightforward.
- MAF Sensor Problems (Petrol Engines): The Mass Airflow (MAF) sensor can become contaminated, resulting in poor performance and fuel economy. Cleaning or replacement may be required.
- EGR Valve Issues (Diesel Engines): The Exhaust Gas Recirculation (EGR) valve can become clogged with carbon deposits, causing performance problems and emissions failures. Regular cleaning or replacement may be necessary.
- Swirl Flap Issues (Diesel Engines): On some diesel engines, the swirl flaps in the intake manifold can fail, potentially causing engine damage. Consider deleting or replacing them if they are known to be problematic.
Transmission Issues:
- Sportronic Automatic Transmission Problems: The Sportronic automatic transmission can suffer from erratic shifting and solenoid failures. Ensure smooth and reliable shifting during a test drive. Fluid changes are critical to its longevity.
- Manual Gearbox Wear: High mileage manual gearboxes may experience synchro wear, especially in the second gear.
Suspension & Steering Issues:
- Front Suspension Wear: The front suspension, particularly the wishbones and ball joints, is prone to wear, leading to knocking noises and poor handling. Listen for noises during a test drive and check for play in the suspension components.
- Rear Suspension Bushings: The rear suspension bushings can also wear, causing similar symptoms.
- Power Steering Pump Failure: Power steering pumps can fail, leading to heavy steering.
Electrical Issues:
- Central Locking Problems: Central locking systems can be unreliable, with doors failing to lock or unlock.
- Window Regulator Failures: Window regulators are prone to failure, causing windows to become stuck.
- Dashboard Display Issues: Some dashboard displays can suffer from pixel loss.
Other Issues:
- Rust: While not as prone to rust as older Alfas, check around the sills, wheel arches, and underbody for any signs of corrosion, especially on pre-facelift models.
- Interior Wear: Check the condition of the leather seats and interior trim for wear and tear.
Driving Experience
The Alfa Romeo 166 offers a rewarding driving experience, characterized by its responsive handling, powerful engines, and comfortable ride. However, it's important to be aware of its pros and cons:
Pros:
- Stylish Design: The 166 is a visually appealing car with a distinctive Italian design.
- Engaging Handling: It offers surprisingly agile and responsive handling for its size.
- Powerful Engines: The V6 petrol and JTDm diesel engines provide ample power and torque.
- Comfortable Ride: The suspension provides a comfortable ride, even on rough roads.
- Driver-Focused Interior: The interior is designed with the driver in mind, with well-placed controls and comfortable seats.
Cons:
- Reliability Issues: As detailed above, the 166 is prone to a number of mechanical and electrical problems.
- Running Costs: Maintenance and repairs can be expensive, especially for the V6 models.
- Fuel Economy: Fuel economy is not a strong point, particularly with the V6 engines.
- Depreciation: The 166 has suffered from significant depreciation, meaning it can lose value quickly.
Buying Advice
If you're considering purchasing an Alfa Romeo 166, here's some advice:
- Year Recommendations: The facelifted models (2003-2007) are generally considered more desirable due to their improved styling, updated interior, and refined mechanicals. The 2.4 JTDm 20v diesel is a good all-around performer.
- Engines to Consider: The 2.4 JTDm diesel engines offer a good balance of performance and fuel economy. The V6 engines are powerful but require more maintenance and have higher running costs.
- What to Avoid: Early pre-facelift models may have more reliability issues. Avoid cars with a poor maintenance history or obvious signs of neglect.
- Inspection Checklist:
- Thoroughly Inspect the Engine: Look for signs of oil leaks, unusual noises, and ensure the timing belt has been recently replaced (with proof).
- Check the Transmission: Ensure smooth shifting with both the manual and Sportronic automatic transmissions.
- Evaluate the Suspension and Steering: Listen for knocking noises and check for play in the suspension components.
- Test All Electrical Systems: Check the central locking, windows, dashboard displays, and other electrical features.
- Inspect for Rust: Look for any signs of corrosion around the sills, wheel arches, and underbody.
- Review Service History: Look for a comprehensive service history that shows regular maintenance and repairs.
- Price Negotiations: Be prepared to negotiate the price based on the car's condition, mileage, and service history. Factor in the potential cost of repairs when making an offer.
The Alfa Romeo 166 can be a rewarding car to own, offering stylish design, engaging driving dynamics, and a comfortable interior. However, it's essential to be aware of its potential reliability issues and to thoroughly inspect any car before purchasing. With careful research and maintenance, you can enjoy the unique experience of owning an Alfa Romeo 166.
