The BMW E39, produced from 1995 to 2003, is often hailed as one of the best BMW 5 Series ever made. But nostalgia can be deceiving. While celebrated for its blend of performance, comfort, and classic styling, the true test of a car lies in its long-term reliability. So, does the E39 live up to the hype years down the line? Let's dive deep into the realities of owning and maintaining an E39 in the modern era.

The Allure of the E39: Why Do People Still Love Them?

Before we delve into the potential pitfalls, let's acknowledge why the E39 remains so desirable. Its appeal goes beyond mere aesthetics.

  • Timeless Design: The E39's elegant lines and balanced proportions haven't aged a day. It avoids the overly aggressive styling of some modern BMWs, presenting a clean and sophisticated look.
  • Driver-Focused Experience: The E39 offers a driving experience that's becoming increasingly rare. Hydraulic steering provides excellent feedback, and the chassis strikes a perfect balance between comfort and handling. It feels connected to the road in a way that many modern cars simply don't.
  • Variety of Engine Options: From the fuel-efficient inline-sixes to the powerful V8s, the E39 offered a wide range of engine choices to suit different needs and preferences. This versatility contributes to its enduring popularity.
  • Relatively Simple Technology: Compared to newer cars, the E39 has fewer electronic gadgets and complex systems. This can be a blessing in disguise, as it reduces the potential for electronic gremlins and makes DIY repairs more feasible.

The Harsh Reality: Common E39 Problems to Watch Out For

Now for the less glamorous side of E39 ownership. These are older cars, and age inevitably takes its toll. Here are some of the most common issues you're likely to encounter:

  • Cooling System Overhaul: The E39's cooling system is notorious for being a weak point. Expect to replace the water pump, thermostat, radiator, expansion tank, and hoses at some point. Preventive maintenance is key here – don't wait for something to fail. A complete cooling system refresh every 75,000-100,000 miles is a good idea.
  • Suspension Component Wear: Bushings, ball joints, and control arms are all susceptible to wear and tear, especially on cars with higher mileage. This can lead to vague handling, clunking noises, and uneven tire wear.
  • VANOS Issues (Variable Valve Timing): VANOS problems are more common on the inline-six engines. Symptoms include rough idling, loss of power, and poor fuel economy. Rebuilding the VANOS unit can restore performance.
  • Rust: While the E39 is generally well-built, rust can still be a problem, particularly in areas with harsh winters or salty roads. Check around the wheel wells, rocker panels, and undercarriage for any signs of corrosion.
  • Electrical Gremlins: Like many older European cars, the E39 can suffer from electrical issues. These can range from faulty sensors to problems with the instrument cluster or central locking system.
  • Oil Leaks: Valve cover gaskets, oil pan gaskets, and rear main seals are common sources of oil leaks on the E39. Keeping an eye on your oil level and addressing leaks promptly can prevent more serious engine damage.
  • Pixel Loss in Instrument Cluster: A common issue is pixel loss on the instrument cluster display. While not detrimental to the car's function, it can be annoying and affect readability. Repair services are available to address this.

Engine-Specific Considerations: What to Expect

The engine under the hood significantly impacts the overall reliability of an E39. Here's a breakdown of the most common engine options:

  • M52/M54 Inline-Six (525i, 528i, 530i): These engines are generally reliable, but the VANOS system is a potential weak point. Cooling system issues are also common. The M54 (found in later models) is slightly more prone to oil consumption.
  • M62 V8 (540i): The M62 is a powerful engine, but it can be more expensive to maintain than the inline-sixes. Timing chain guides are a known issue, and they can fail catastrophically if not addressed. Oil leaks are also common.
  • S62 V8 (M5): The S62 is a high-performance engine that requires meticulous maintenance. It's more complex and expensive to repair than the other engines. VANOS issues, rod bearing failure, and oil leaks are all potential concerns.

The Cost of Ownership: Are You Prepared?

Owning an E39 isn't cheap, especially if you want to keep it in good condition. Here's a realistic look at the potential costs:

  • Purchase Price: E39 prices vary widely depending on condition, mileage, and model. Expect to pay anywhere from $5,000 to $20,000+ for a well-maintained example.
  • Maintenance and Repairs: Budget for regular maintenance, including oil changes, fluid flushes, and inspections. Be prepared for unexpected repairs, as older cars are more likely to experience breakdowns.
  • Parts Availability: Parts for the E39 are generally readily available, but some parts can be expensive, especially for the M5.
  • DIY vs. Professional Repairs: If you're mechanically inclined, you can save money by doing some repairs yourself. However, some jobs are best left to professionals.
  • Insurance: Insurance costs will vary depending on your location, driving record, and the specific model you own.

It's crucial to have a financial cushion to cover unexpected repairs. Setting aside a dedicated fund for E39 maintenance is a smart move.

Finding a Good E39: What to Look For

If you're considering buying an E39, thorough inspection is essential. Here's what to look for:

  • Service History: A complete and detailed service history is a must. This will give you valuable insights into how the car has been maintained.
  • Pre-Purchase Inspection (PPI): Have a qualified mechanic perform a PPI before you buy the car. This will help you identify any potential problems.
  • Rust: Carefully inspect the car for rust, especially around the wheel wells, rocker panels, and undercarriage.
  • Engine Condition: Listen for any unusual noises from the engine. Check for oil leaks and signs of overheating.
  • Transmission Condition: Test the transmission to ensure it shifts smoothly and doesn't slip.
  • Suspension Condition: Check for worn suspension components and listen for any clunking noises.
  • Electrical System: Test all the electrical components, including the lights, windows, locks, and radio.
  • Interior Condition: Inspect the interior for wear and tear. Check the seats, carpets, and dashboard.
  • Test Drive: Take the car for a thorough test drive to assess its overall performance and handling.

Don't be afraid to walk away from a car that has too many red flags. There are plenty of E39s out there, so be patient and find one that's in good condition.

Tips for Keeping Your E39 Reliable: Proactive Maintenance

The key to long-term E39 reliability is proactive maintenance. Here are some tips:

  • Follow the Manufacturer's Recommended Maintenance Schedule: Adhere to the recommended maintenance intervals for oil changes, fluid flushes, and other services.
  • Address Problems Promptly: Don't ignore warning signs or small problems. Addressing them promptly can prevent them from escalating into more serious and expensive issues.
  • Use Quality Parts: Use genuine BMW parts or high-quality aftermarket parts. Avoid cheap, inferior parts that are likely to fail prematurely.
  • Keep the Car Clean: Regular washing and waxing can help protect the paint and prevent rust.
  • Store the Car Properly: If you're not driving the car regularly, store it in a dry, covered location to protect it from the elements.
  • Join an E39 Forum: Connect with other E39 owners and learn from their experiences. Online forums are a great resource for information and advice.
