Volvo S40 (Second Generation): A Comprehensive Guide

The Volvo S40 (second generation, internally designated the P1 platform) is a compact executive car produced by Volvo from 2004 to 2012. Representing a significant departure from its predecessor, the second-generation S40 offered a blend of Swedish safety, Scandinavian design, and a more engaging driving experience. It competes primarily with the Audi A3 Sedan, BMW 1 Series (sedan version in some markets), and Mercedes-Benz C-Class.

Generations

  • Second Generation (2004-2012, P1 platform):
    • 2004-2007 (Pre-Facelift): Introduced with a range of petrol and diesel engines. Known for its distinctive "floating" center console and emphasis on safety features.
    • 2008-2012 (Facelift): Significant exterior and interior revisions. Included redesigned front and rear fascias, improved materials, and enhanced technology features. Powertrain options remained largely similar, with some revisions for improved efficiency.

Reliability & Common Issues

The second-generation Volvo S40, while generally a reliable vehicle, is subject to certain common issues that prospective buyers should be aware of. Regular maintenance is key to longevity.

  • Engine Issues:
    • Turbocharger Problems (T5 Models): The turbocharger on the T5 engine can be prone to failure, especially if oil changes are neglected. Look for signs of excessive oil consumption or turbo whine. Regularly changing the oil with a high-quality synthetic is crucial.
    • Coil Pack Failures: Ignition coil failures are relatively common, particularly on higher-mileage examples. Misfires or rough idling are typical symptoms. Replacement is generally straightforward.
    • EGR Valve Problems (Diesel Engines): On diesel variants, the Exhaust Gas Recirculation (EGR) valve can become clogged with carbon deposits, leading to reduced performance and engine management light illumination. Regular cleaning or replacement may be necessary.
    • Timing Belt Replacement (Non-Interference Engines): Most petrol S40 engines are non-interference engines. A broken timing belt is a costly affair, though not immediately catastrophic. Scheduled replacement is crucial, especially on older models. Always verify that timing belt service has been performed according to the manufacturer's recommendations.
  • Electrical Issues:
    • Central Electronic Module (CEM) Problems: The CEM, responsible for controlling various electrical functions, can sometimes develop faults. Symptoms may include intermittent electrical issues, such as problems with the windows, lights, or central locking. Diagnosis and repair can be complex and potentially expensive.
    • ABS Sensor Failures: ABS sensor failures are common, triggering the ABS warning light. Diagnosis requires a scan tool to pinpoint the affected sensor.
  • Suspension and Steering:
    • Front Suspension Wear: The front suspension, particularly the lower control arm bushings and ball joints, is prone to wear, leading to clunking noises and reduced handling precision. Inspection and replacement may be required.
    • Power Steering Pump Noise: The power steering pump can become noisy over time, especially when cold. Flushing the power steering fluid and replacing the pump may be necessary.
  • Other Issues:
    • Interior Trim Wear: Some interior trim pieces, particularly the soft-touch materials on the dashboard and door panels, can be prone to scratching and wear.
    • AC Condenser Leaks: The AC condenser can be susceptible to leaks, leading to reduced air conditioning performance. Inspection for leaks and replacement may be necessary.
    • Rust (Specific Regions): While Volvo employed good rust prevention measures, cars operated in areas with heavy road salt usage may experience rust, particularly around the wheel arches and undercarriage. Thoroughly inspect for rust before purchase.

Driving Experience

The Volvo S40 offers a well-rounded driving experience, balancing comfort, safety, and performance. It leans more towards comfort and safety than outright sportiness, but it's still an enjoyable car to drive.

  • Pros:
    • Comfortable Ride: The S40 provides a smooth and comfortable ride, making it well-suited for long journeys.
    • Refined Engines: The petrol and diesel engines offer a good balance of performance and fuel economy. The T5 engine, in particular, provides strong acceleration.
    • High Safety Standards: Volvo is renowned for its commitment to safety, and the S40 is equipped with a comprehensive range of safety features, including multiple airbags, ABS, and stability control.
    • Stylish Interior: The interior design is modern and stylish, with comfortable seats and a user-friendly layout. The "floating" center console is a distinctive feature.
    • Good Fuel Economy: Diesel versions offer excellent fuel economy.
  • Cons:
    • Rear Seat Space: Rear seat space is somewhat limited compared to some competitors.
    • Steering Feel: The steering feel is not as sharp or engaging as some sports sedans.
    • Turning Radius: The turning radius can be larger than expected, making parking in tight spaces somewhat challenging.
    • Potential for Expensive Repairs: As with any European car, repairs can be more expensive than those for domestic or Japanese vehicles.

Buying Advice

When considering a used Volvo S40, keep the following points in mind:

  • Years to Look For: The facelifted models (2008-2012) are generally preferable due to their updated styling, improved interior materials, and enhanced technology features. However, well-maintained pre-facelift models can also be a good value.
  • Years to Potentially Avoid (with Caution): No specific years should be entirely avoided. The key is to find a well-maintained example, regardless of the model year. However, very early models (2004-2005) might exhibit more wear and tear simply due to their age.
  • Engine Choice:
    • T5: For those seeking performance, the T5 engine is a good choice. However, be sure to check for turbocharger issues and ensure regular oil changes have been performed.
    • 2.4i/2.0: These petrol engines offer a good balance of performance and fuel economy.
    • Diesel (D4, D5): Diesel engines provide excellent fuel economy and are well-suited for long-distance driving. Be mindful of potential EGR valve problems and ensure regular maintenance.
  • Pre-Purchase Inspection: A thorough pre-purchase inspection by a qualified mechanic is essential. Pay particular attention to the engine, transmission, suspension, brakes, and electrical system.
  • Maintenance Records: Review the maintenance records carefully to ensure that the car has been properly serviced. Look for evidence of regular oil changes, timing belt replacements, and other scheduled maintenance items.
  • Check for Rust: Inspect the car carefully for rust, especially around the wheel arches, undercarriage, and door sills.
  • Test Drive: Take the car for a thorough test drive to assess its performance, handling, and overall condition. Listen for any unusual noises or vibrations.
  • Negotiate Price: Be prepared to negotiate the price based on the car's condition, mileage, and history. Research comparable vehicles to get a sense of fair market value.
